INJECTION PORT
TECHNICAL FIELD
[0001] The present invention relates generally to medical implants and appliers and, more particularly, to an injection port for use with a variety of medical implants and appliers. The invention will be disclosed in connection with, but not limited to, surgically implantable injection ports and an applier therefor.
BACKGROUND
TECHNICAL FIELD
[0001] The present invention relates generally to medical implants and appliers and, more particularly, to an injection port for use with a variety of medical implants and appliers. The invention will be disclosed in connection with, but not limited to, surgically implantable injection ports and an applier therefor.
BACKGROUND
[0002] Injection ports are generally placed beneath the skin of a patient and have a variety of uses such as, for example, infusing medication, blood draws, and adjusting gastric bands. Since the early 1980s, adjustable gastric bands have provided an effective alternative to gastric bypass and other irreversible surgical weight loss treatments for the morbidly obese. A gastric band is generally wrapped around an upper portion of a patient's stomach such that a stoma is formed that restricts the passage of food from an upper portion to a lower portion of the stomach. When the gastric band is in place, and when the stoma is of the appropriate size, food held in the upper portion of the stomach provides a feeling of fullness that discourages overeating. However, initial maladjustment of the gastric band, or a change in the stomach over time, may lead to a stoma of inappropriate size that warrants adjusting the gastric band. For example, a patient may suffer vomiting attacks and discomfort if the stoma is too small to reasonably pass food. If the stoma is too large, and fails to slow food moving from the upper portion of the stomach, the gastric band may need to be tightened.
[0003]
Gastric bands are generally adjusted with an inwardly directed inflatable balloon, similar to a blood pressure cuff, into which fluid, such as saline, is injected. Fluid and the like is frequently injected into the inflatable balloon with a fluid injection port that may be used to achieve a desired diameter. Because adjustable gastric bands generally remain in the patient for long periods of time, the fluid injection port is typically installed subcutaneously to avoid infection. Adjusting the amount of fluid in the adjustable gastric band is generally achieved by inserting a Huber needle through the skin into a silicon septum of the injection port. Once the needle is removed, the septum seals against the hole. A
flexible conduit communicates between the injection port and the adjustable gastric band.

[0004]
The silicone septum is generally partially self-healing such that multiple needle sticks may be performed before the septum becomes ineffective. This self-healing feature is generally achieved by applying an axial compressive load to the septum when it is assembled with the injection port. This axial force is generally achieved by sandwiching the septum between two adjacent pieces during assembly such that the septum will be compressively loaded throughout the duration of the procedure. This compressive load is often able to reseal imperfections in the septum caused by needle sticks.

This compressive load is often able to reseal imperfections in the septum caused by needle sticks.
[0005]
Although the septum has the ability to self-heal after a number of needle sticks, this ability may begin to deteriorate as the septum is continually punctured due to, in part, the inability of the axial compressive load to reseal imperfections. Because injection ports are generally implantable, a gastric banding procedure or the like may have to be shortened or interrupted in order to remove and/or replace an injection port where a septum has become less effective or ineffective. Such a procedure may increase the costs to both the patient and the hospital and may pose a health risk to the patient if a surgical procedure is required to remove the injection port. Additionally, a gastric band or the like may be less effective if fluids or the like are able to diffuse or leak out as the septum loses integrity.

[0006]
It would therefore be advantageous to provide a septum that has a longer useful life. It would be further advantageous to provide a septum that effectively reseals after a plurality of needle sticks and may be more easily assembled using conventional assembly mechanisms.

DETAILED DESCRIPTION
100171 In the following description, like reference characters designate like or corresponding parts throughout the several views. Also, in the following description, it is to be understood that terms such as front, back, inside, outside, and the like are words of convenience and are not to be construed as limiting terms. Terminology used in this patent is not meant to be limiting insofar as devices described herein, or portions thereof, may be attached or utilized in other orientations. Referring in more detail to the drawings, an embodiment of the invention will now be described.
Referring to FIG. 1, an environmental view of one version of a gastric band assembly 6 is shown having a gastric band 8 connected to an injection port 10 by a delivery portion 13. The gastric band 8 may be placed about the patient's stomach 9 such that the delivery or removal of fluid or the like via the injection port 10 will adjust the size of the stoma created by the gastric band 8. The injection port 10 may be retained within the patient's body, such as by affixing the injection port 10 to the patient's musculature, such that access to the gastric band assembly is achieved by inserting a Huber needle or the like into the patient and into the injection port 10.
[0019] Referring to FIG. 2, an implantable injection port 10 has a port body 11 and a delivery portion 13, where the port body 11 is configured to house a septum 16 therein.
Versions of the septum 16 and port body 11 disclosed herein may be used with any suitable port or delivery means such as those, for example, disclosed in co-pending United States Patent Application Serial Number 10/741,875, filed December 19, 2003, titled "Subcutaneous Self Attaching Injection Port With Integral Moveable Retention Members".
Additionally, this application makes reference to the following United States Patent applications, all of which were filed on December 19, 2003: Application Serial No.
10/741,127 titled "Subcutaneous Injection Port For Applied Fasteners";
Application Serial No. 10/10.741,875 titled "Subcutaneous Self Attaching Injection Port With Integral Moveable Retention Members"; and Application Serial No. 10/741,868 titled "Subcutaneous Self Attaching Injection Port With Integral Fasteners". It will be appreciated that the septum 16 may be used with any implantable medical device for which it is suited, including by way of example only, pace makers, vascular access ports, injection ports, such as those used with gastric bands, and gastric pacing devices.
[00201 Referring to FIG. 3, the port body 11 includes a septum retainer 14, configured as a substantially annular band, that includes a base 17 and a collar 19 operably configured to retain a septum 16 therein. The base 17 and collar 19 of the septum retainer 14, when coupled, may be operably configured to provide radial and axial compression forces to the septum 16. The collar 19 further includes an annular rim 15 through which the septum 16 may protrude when retained within the internal cavity 25 of the septum retainer 14.
In one version, as illustrated in FIG. 3, the septum 16 is a substantially conical disk having a bottom surface 32, a top surface 34, and a tapered surface 40.
The septum 16 may taper from the bottom surface 32 to the top surface 34 where, for example, the diameter of the bottom surface 32 is greater than that of the top surface 34. In one version, by tapering the septum 16, and by configuring the collar 19 with a corresponding taper, the septum 16 may be compressed radially as the collar 19 pushes inward during assembly.
This inward compression may create radial compression that beneficially reseals imperfections within the septum 16 after it is stuck with a needle. In one version, the septum 16 includes a base 36 that is not tapered, where the base may be configured to sit flush with the annular flat 18 of the base 17 for support. The septum 16 may initially be larger than the internal cavity 25 such that it must be compressed when the base 17 and the collar 19 are assembled to fit therein. Axial compression may be created by compressing the septum 16 between the annular rim 15 and the annular flat 18.
[0022] It will be appreciated that the septum 16 may be configured from any suitable biocompatible material such as, for example, silicone. The angle a of the taper, defined by the vectors of the bottom surface 34 and the tapered surface 40, may be from about 100 to about 80 , from about 20 to about 70 , from about 30 to about 60 , from about 55 to about 70 , at about 65 , and/or at any other suitable angle. In one version, the septum 16 may be provided with multiple angle variations such that varying levels of radial and/or axial compression act upon the septum 16. For example, the angle of the taper at the bottom surface of the septum may be 65 and the angle of the taper towards the top surface may be 70 . It is further contemplated that the angle of the taper may gradually change and/or that the angle of the taper include a series of angle changes between which the angle remains constant.
[0023]
Referring to FIGS. 4-5, an alternative version of a port body 111 is shown operably configured to apply multi-directional compression forces, such as an axial and a radial compressive force, to a septum 116. The port body 111 includes a septum retainer 114, where the septum retainer 114 is a substantially annular component that includes a base 117 and a collar 119 operably configured to retain a septum 116 therein.
The base 117 and the collar 119 of the septum retainer 114, when coupled, may be operably configured to apply radial and axial compression forces against the septum 116. The collar 119 further includes an annular rim 115 through which the septum 116 may protrude.
[0024]
In one version, the septum 116 is a substantially annular disk, having a bottom surface 132 and a top surface 134, that is constructed from an elastomeric material such as, for example, silicone. The septum 116 may be configured such that its diameter is greater than that of the internal cavity 125 prior to insertion. The collar 119 may be provided with an angled lead-in 150 that is operably configured to radially squeeze the septum 116 and facilitate its insertion into the internal cavity 125 during assembly. As it is inserted, the septum 116 may be compressed by the angled lead-in 150 until it fits securely within the reduced diameter of the internal cavity 125. The insertion of the elastomeric septum 116 may result in radial compression therein as the elastomeric material tries to expand against the collar 119. The radial compression of the septum 116 may facilitate resealing after one or a plurality of needle sticks.
[0025]
In addition to radial compression, axial compression may be applied by coupling the base 117 with the collar 119 of the septum retainer 114. For example, the septum 116 may be axially compressed between an annular flat 118 on the base 117 and the annular rim 115 of the collar 119 during assembly. The septum 116 may be configured such that, when the base 117 and the collar 119 are coupled, the elastomeric material of the septum 116 is compressed and held, thereby creating axial compression forces therein. For example, the initial height of the septum 116 may be greater than the distance between the base 117 and collar 119 when coupled. In the illustrated version, both axial and radial compression forces may be created simultaneously to improve the resealability of the septum 116.
Providing multiple compression forces may reseal those defects or the like that would remain unsealed should only a unidirectional force be provided.
[0026]
It will be appreciated that the septum 116 may be configured from any suitable biocompatible and/or elastomeric material such as, for example, silicone. It will also be appreciated that the septum 116 may also include a tapered surface. The collar 119 may include any suitable angled lead-in 150 having an angle suitable for facilitating the insertion of the septum 115 into the septum retainer 114. It is further contemplated that, for example, the septum 116 may be pre-compressed prior to insertion where, upon insertion into the collar 119, the pre-compression on the septum 116 could be released such that it presses against the sides of the septum retainer 114.
[0027] Providing compressive force in multiple directions simultaneously, such as in a radial and axial direction, may increase the number of times a septum may be stuck with a needle or the like before becoming less effective or ineffective. Increasing the longevity of the septum may increase the life of the injection port and/or the accompanying medical device. Increasing the longevity of the injection port may increase the efficiency, safety, and/or accuracy of procedures and instruments with which the injection port or the like is used.
[0028]
It will be appreciated that any suitable multi-directional forces may be provided by any suitable means to facilitate improved self-healing of the septum after a needle puncture. For example, multi-directional compression forces may be achieved by coupling the septum and the septum retainer with a simple arbor press adapted to apply axial pressure. The multi-directional compression forces may be achieved by the axial force of the arbor press effecting radial compression forces as the septum and the septum retainer are engaged. Multi-directional forces, such as axial compression forces and radial compression forces, may be achieved simultaneously or in succession. For example, in one version, a septum and a septum retainer may be axially compressed when assembled with an acorn press or the like. Radial compression may then be achieved by providing the septum retainer with an annular band around the circumference thereof that, when adjusted, applies radial pressure to the septum in addition to the compressive axial force created by the acorn press.
[0029]
It will be appreciated that the septum and/or septum retainer may be configured to apply any suitable level of compressive force, unidirectionally or multi-directionally. For example, adjusting the angle of the septum taper, providing a taper with varying angles, adjusting the angle of the septum retainer taper, adjusting the shape or size of the annular flat, altering the size of the septum, altering the shape of the angled lead-in, and/or adding a radial compression band (not shown), may create or modify the multi-directional forces.
The septum retainer, the port body, and/or any other components may be made of any suitable material having sufficient stiffness and strength such as, for example, polyetheretherketon (known as PEEK).
[0030] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the spirit and scope of the appended claims. Additionally, each element described in relation to the invention may be alternatively described as a means for performing that element's function.
For example, it will become readily apparent to those skilled in the art, given the benefit of the present disclosure, that the above invention has equal applicability to other types of implantable bands. For example, bands are used for the treatment of fecal incontinence. One such band is described in U.S. Patent 6,461,292. Bands can also be used to treat urinary incontinence. One such band is described in U.S. Patent Application 2003/0105385. Bands can also be used to treat heartburn and/or acid reflux.
One such band is described in U.S. Patent 6,470,892. Bands can also be used to treat impotence. One such band is described in U.S. Patent Application Publ. No. 2003/0114729. Further, a hydraulically inflatable therapeutic member may comprise an exteriorly adjustable bladder that actuates by expanding in length and/or outer diameter, such as a penile implant.
Application Serial No. 10/10.741,875 titled "Subcutaneous Self Attaching Injection Port With Integral Moveable Retention Members"; and Application Serial No. 10/741,868 titled "Subcutaneous Self Attaching Injection Port With Integral Fasteners". It will be appreciated that the septum 16 may be used with any implantable medical device for which it is suited, including by way of example only, pace makers, vascular access ports, injection ports, such as those used with gastric bands, and gastric pacing devices.
[00201 Referring to FIG. 3, the port body 11 includes a septum retainer 14, configured as a substantially annular band, that includes a base 17 and a collar 19 operably configured to retain a septum 16 therein. The base 17 and collar 19 of the septum retainer 14, when coupled, may be operably configured to provide radial and axial compression forces to the septum 16. The collar 19 further includes an annular rim 15 through which the septum 16 may protrude when retained within the internal cavity 25 of the septum retainer 14.
In one version, as illustrated in FIG. 3, the septum 16 is a substantially conical disk having a bottom surface 32, a top surface 34, and a tapered surface 40.
The septum 16 may taper from the bottom surface 32 to the top surface 34 where, for example, the diameter of the bottom surface 32 is greater than that of the top surface 34. In one version, by tapering the septum 16, and by configuring the collar 19 with a corresponding taper, the septum 16 may be compressed radially as the collar 19 pushes inward during assembly.
This inward compression may create radial compression that beneficially reseals imperfections within the septum 16 after it is stuck with a needle. In one version, the septum 16 includes a base 36 that is not tapered, where the base may be configured to sit flush with the annular flat 18 of the base 17 for support. The septum 16 may initially be larger than the internal cavity 25 such that it must be compressed when the base 17 and the collar 19 are assembled to fit therein. Axial compression may be created by compressing the septum 16 between the annular rim 15 and the annular flat 18.
[0022] It will be appreciated that the septum 16 may be configured from any suitable biocompatible material such as, for example, silicone. The angle a of the taper, defined by the vectors of the bottom surface 34 and the tapered surface 40, may be from about 100 to about 80 , from about 20 to about 70 , from about 30 to about 60 , from about 55 to about 70 , at about 65 , and/or at any other suitable angle. In one version, the septum 16 may be provided with multiple angle variations such that varying levels of radial and/or axial compression act upon the septum 16. For example, the angle of the taper at the bottom surface of the septum may be 65 and the angle of the taper towards the top surface may be 70 . It is further contemplated that the angle of the taper may gradually change and/or that the angle of the taper include a series of angle changes between which the angle remains constant.

The port body 111 includes a septum retainer 114, where the septum retainer 114 is a substantially annular component that includes a base 117 and a collar 119 operably configured to retain a septum 116 therein.
The base 117 and the collar 119 of the septum retainer 114, when coupled, may be operably configured to apply radial and axial compression forces against the septum 116. The collar 119 further includes an annular rim 115 through which the septum 116 may protrude.
[0024]
In one version, the septum 116 is a substantially annular disk, having a bottom surface 132 and a top surface 134, that is constructed from an elastomeric material such as, for example, silicone. The septum 116 may be configured such that its diameter is greater than that of the internal cavity 125 prior to insertion.

In addition to radial compression, axial compression may be applied by coupling the base 117 with the collar 119 of the septum retainer 114. For example, the septum 116 may be axially compressed between an annular flat 118 on the base 117 and the annular rim 115 of the collar 119 during assembly. The septum 116 may be configured such that, when the base 117 and the collar 119 are coupled, the elastomeric material of the septum 116 is compressed and held, thereby creating axial compression forces therein. For example, the initial height of the septum 116 may be greater than the distance between the base 117 and collar 119 when coupled. In the illustrated version, both axial and radial compression forces may be created simultaneously to improve the resealability of the septum 116.
Providing multiple compression forces may reseal those defects or the like that would remain unsealed should only a unidirectional force be provided.
[0026]
It will be appreciated that the septum 116 may be configured from any suitable biocompatible and/or elastomeric material such as, for example, silicone. It will also be appreciated that the septum 116 may also include a tapered surface. The collar 119 may include any suitable angled lead-in 150 having an angle suitable for facilitating the insertion of the septum 115 into the septum retainer 114. It is further contemplated that, for example, the septum 116 may be pre-compressed prior to insertion where, upon insertion into the collar 119, the pre-compression on the septum 116 could be released such that it presses against the sides of the septum retainer 114.
[0027] Providing compressive force in multiple directions simultaneously, such as in a radial and axial direction, may increase the number of times a septum may be stuck with a needle or the like before becoming less effective or ineffective. Increasing the longevity of the septum may increase the life of the injection port and/or the accompanying medical device. Increasing the longevity of the injection port may increase the efficiency, safety, and/or accuracy of procedures and instruments with which the injection port or the like is used.
[0028]
It will be appreciated that any suitable multi-directional forces may be provided by any suitable means to facilitate improved self-healing of the septum after a needle puncture. For example, multi-directional compression forces may be achieved by coupling the septum and the septum retainer with a simple arbor press adapted to apply axial pressure. The multi-directional compression forces may be achieved by the axial force of the arbor press effecting radial compression forces as the septum and the septum retainer are engaged. Multi-directional forces, such as axial compression forces and radial compression forces, may be achieved simultaneously or in succession. For example, in one version, a septum and a septum retainer may be axially compressed when assembled with an acorn press or the like. Radial compression may then be achieved by providing the septum retainer with an annular band around the circumference thereof that, when adjusted, applies radial pressure to the septum in addition to the compressive axial force created by the acorn press.
[0029]
It will be appreciated that the septum and/or septum retainer may be configured to apply any suitable level of compressive force, unidirectionally or multi-directionally. For example, adjusting the angle of the septum taper, providing a taper with varying angles, adjusting the angle of the septum retainer taper, adjusting the shape or size of the annular flat, altering the size of the septum, altering the shape of the angled lead-in, and/or adding a radial compression band (not shown), may create or modify the multi-directional forces.
The septum retainer, the port body, and/or any other components may be made of any suitable material having sufficient stiffness and strength such as, for example, polyetheretherketon (known as PEEK).
[0030] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the spirit and scope of the appended claims. Additionally, each element described in relation to the invention may be alternatively described as a means for performing that element's function.
For example, it will become readily apparent to those skilled in the art, given the benefit of the present disclosure, that the above invention has equal applicability to other types of implantable bands. For example, bands are used for the treatment of fecal incontinence. One such band is described in U.S. Patent 6,461,292. Bands can also be used to treat urinary incontinence. One such band is described in U.S. Patent Application 2003/0105385. Bands can also be used to treat heartburn and/or acid reflux.
One such band is described in U.S. Patent 6,470,892. Bands can also be used to treat impotence. One such band is described in U.S. Patent Application Publ. No. 2003/0114729. Further, a hydraulically inflatable therapeutic member may comprise an exteriorly adjustable bladder that actuates by expanding in length and/or outer diameter, such as a penile implant.
