Definitions
- This invention relates to a transcutaneous access device. It relates more particularly to a device of this type to facilitate access to the body through the skin by catheters and similar percutaneous devices.
- catheters are used to access a patient's venous system for the administration of intravenous (IV) fluids, antibiotics, and chemotherapy.
- IV intravenous
- Catheters are also implanted in patients who require repeated access to the peritoneum for peritoneal dialysis.
- a catheter has been devised which includes a button-like skirt with a raised neck and a central hole for accommodating a tube.
- the tube has a corrugated segment extending above the button neck which allows the external portion ofthe tube to be flexed so as to absorb shocks.
- the skirt including a portion ofthe neck thereof, is covered with a porous material, such as polyester, velour, to allow for cell infiltration.
- a porous material such as polyester, velour
- the present invention aims to provide a transcutaneous access device for a catheter which should circumvent most ofthe problems caused by relative movement ofthe catheter and the tissue surrounding the catheter.
- Another object ofthe invention is to provide a transcutaneous access device which, when implanted, provides a tight biological seal between the device and adjacent tissue.
- a further object ofthe invention is to provide a device of this type which reduces the risk of infection;
- Yet another object ofthe invention is to provide a transcutaneous access device which is relatively easy to manufacture in quantity.
- the transcutaneous access device of this invention comprises a flat button with an opening therethrough and an integral upstanding tubular neck in registration with that opening. Formed as an integral extension of that neck is a pleated tube or bellows whose free end is terminated by a collar which is arranged to connect mechanically to a conventional access catheter that extends all the way through the lumen formed by the skirt, neck and button ofthe access device.
- the lumen ofthe present device is large enough to provide appreciable clearance between the walls ofthe lumen and the catheter so as to minimize contact between the access device and the catheter.
- FIG. 1 is an isometric view with parts broken away of a transcutaneous access device incorporating the invention
- FIG. 2 is a sectional view with parts in elevation showing the FIG. 1 access device implanted in the body and ready for use.
- my access device comprises a flat, button-like main body or skirt 10 having a central opening 12 and an array of three to five through-holes 14 distributed around opening 12. Extending out from one side of skirt 10 in registration with opening 12 is an integral, tubular neck 16 whose lumen is in registration with opening 12. In the illustrated device, the neck 16 extends out from skirt 10 at an angle; however, the neck could just as well be perpendicular to the skirt 10.
- the device also includes a flexible, tubular sleeve 22 extending from the free end of neck 16.
- sleeve 22 is a pleated accordion-like tube which forms a bellows and which is terminated at its free end by a cylindrical collar 24.
- the sleeve 22 allows the collar 24 to be moved toward and away from neck 16 as well as in all directions about the longitudinal axis of neck 16.
- the skirt 10, neck 16, sleeve 22 and collar 24 define a continuous uniformly sized lumen 25 which extends through the entire device.
- the collar 24 is formed with an internal lip 24a to provide a mechanical connection to an associated access catheter as will be described later.
- the access device including the skirt 10, neck 16, sleeve 22 and collar 24 are preferably formed of a flexible, thermally stable, biocompatible material such as flexible medical grade polyurethane.
- the accordion-like sleeve 22 may be configured by placing a tubular extension of the neck 16 in a heated female mold and applying gas pressure inside the tube to force the tube walls to conform to the mold. The neck may then be secured to the button skirt 10 by welding.
- the device may be molded as a unitary part.
- the entire surface ofthe body or skirt 10 is covered by a porous covering or bed
- Such a covered skirt 10 is available as Part No. 600K61121, from the U.S Catheter and Instrument Company of Glenfalls, New York. The covering encourages cell infiltration and the formation of subcutaneous tissue and collagen.
- the skirt 10 is in the order of 2.5 cm in diameter, the neck 16 is about 0.5 cm long, the sleeve 22 is about 2 to 24 cm long and the diameter ofthe device's lumen 25 is in the order of 0.4 to 0.8 cm.
- skirt 10 may be smaller, e.g., 1 cm in diameter, with the lengths ofthe neck and skirt being 0.5 cm and 0.4 cm, respectively. In that event, the lumen 25 diameter may be in the order of 0.3 to 0.5 cm.
- the access device is implanted so that the skirt 10 is anchored in the subcutaneous tissue 32 and the neck 16 penetrates the dermal layer 34 and epidermal layer 36 of the skin S.
- tissue growth penetrates the through-holes 14 to help anchor the access device.
- the covering 26 provides a porous bed to encourage the growth of tissue and collagen around the body 10 to provide a biological seal with the epidermal cells which migrate or invaginate along neck 16 until they reach the covering 26.
- the access device is designed to be used in conjunction with an access catheter such as the one shown generally at 42 in FIG. 2.
- the illustrated catheter is a vascular access catheter. However, the catheter could just as well be a peritoneal access catheter.
- the catheter 42 includes a tube 44 which has an internal segment 44a which extends from the skin line along neck 16 and through body 10 to a selected infusion site such as the subclavian vein.
- the catheter tube also includes an external segment 44b which extends from the skin line through sleeve 22 and collar 24 to a Y-fitting 46 to which is connected a pair of fluid inlet tubes 48a and 48b so as to allow fluid from two different sources to be flowed to the catheter tube 44.
- the lip 24a ofthe device's collar 24 is arranged to releasably engage over a radial flange 46a usually present at the lower end ofthe catheter fitting 46 to mechanically connect the catheter to the access device at the free end ofthe device's flexible sleeve 22.
- the device's lumen 25 is sized to minimize contact with the catheter tube 44 and so as not to inhibit motion ofthe catheter tube. Therefore, any motion ofthe internal catheter tube segment 44a caused by movements ofthe patient's body is substantially decoupled from the implanted portions ofthe access device, i.e., skirt 10 and neck 16.
- the accordion sleeve 22 is able to flex, extend and contract as needed to accommodate such movement so that essentially no motion is coupled to the implanted portions ofthe access device. Resultantly, a tight biological seal is maintained between the access device and the surrounding tissue.
