Definitions
- the present invention relates generally to medical devices and methods. More particularly, the invention relates to apparatus and methods for independently delivering a plurality of luminal prostheses within a body lumen.
- Stenting has become an increasingly important treatment option for patients with coronary artery disease. Stenting involves the placement of a tubular prosthesis within a diseased coronary artery to expand the arterial lumen and maintain the patency of the artery. Early stent technology suffered from problems with restenosis, the tendency of the coronary artery to become re-occluded following stent placement. In recent years, however, improvements in stent design and the advent of drug-eluting stents have reduced restenosis rates dramatically. As a result, the number of stenting procedures being performed in the United States, Europe, and elsewhere has risen.
- Stents are delivered to the coronary arteries using long, flexible vascular catheters, typically inserted through a femoral artery.
- the stent is simply released from the delivery catheter, and it resiliency expands into engagement with the vessel wall.
- a balloon on the delivery catheter is expanded which expands and deforms the stent to the desired diameter, whereupon the balloon is deflated and removed.
- stent delivery catheters are not capable of customizing the length of the stent in situ to match the size of the lesion to be treated. While lesion size may be measured prior to stenting using angiography or fluoroscopy, such measurements may be inexact. If a stent is introduced that is found to be of inappropriate size, the delivery catheter and stent must be removed from the patient and replaced with a different device of correct size. Moreover, current stent delivery devices cannot treat multiple lesions with a single catheter. If multiple lesions are to be treated, a new catheter and stent must be introduced for each lesion to be treated.
- a balloon or other expandable member may also interfere with stent advancement, especially after the balloon has been inflated and deflated multiple times and, thus, becomes somewhat flaccid and/or deformed.
- stent delivery devices in which the stents directly contact the expandable member may lead to increased risk of balloon or stent damage, increased general wear and tear, difficult stent advancement along the delivery device, and less precise stent placement.
- devices and methods of the present invention provide for delivering prostheses such as stents and grafts into body lumens.
- devices of the invention include a catheter having a stent shuttle for carrying stents in such a way that they do not directly contact an expandable balloon of the catheter.
- Stents or stent segments
- Stents are typically deployed from the catheter by retracting a sheath and/or advancing the stents along the shuttle using a stent pushing device.
- An expandable balloon is then inflated to expand the shuttle, which in turn expands one or more stent segments.
- Such devices and methods may be used to individually deploy single stents, groups of stents, or single or multiple stent segments in a body lumen while avoiding direct contact between the expandable deployment balloon and the stents.
- stents and “stent segments” are used frequently in this application.
- the term “stent” is well known in the art, and some stents are segmented into two or more stent segments. Generally, adjacent stent segments of one stent may be connected, partially connected, breakably connected, or completely separate.
- Methods and apparatus of the present invention are generally used to deliver multiple stents, multiple stent segments or both in a body lumen such as a blood vessel. In various embodiments, for example, multiple stents each having multiple segments, multiple segments of one stent, and or multiple non- segmented stents may be delivered.
- the same embodiment of a device or method maybe used to deliver multiple stents, multiple segments of one stent, multiple segments of multiple stents and/or the like. Therefore, the terms “stents” and “stent segments” may sometimes be used interchangeably throughout the application and such terms should not be interpreted to limit the scope of the invention in any way.
- the sheath may be disposed over the shuttle, while in alternative embodiments the shuttle may be disposed over the sheath.
- the shuttle is disposed over the sheath, and the sheath is disposed over the expandable member.
- the sheath may be disposed over the shuttle, with the shuttle being disposed over the expandable member. In either case, moving the sheath axially toward the proximal end of the catheter shaft will expose (or further expose) at least part of the expandable member, allowing it to expand against the shuttle to cause the shuttle to radially expand, thus causing at least one of the plurality of stent segments to expand.
- the at least one stent segment comprises a first selected number of stent segments.
- a second selected number of stent segments may be deployed in subsequent steps.
- the device may be used not only to deploy one custom length stent but multiple custom length stents in some embodiments.
- the shuttle may be slidably disposed over the sheath and the catheter shaft.
- the stent segments may either be fixed to the shuttle until they are expanded into a deployed position or slidably disposed along the shuttle.
- the device may also include a stent pushing member disposed over the shuttle, proximal to the plurality of stent segments, for advancing the stent segments along the shuttle in a direction from proximal to distal.
- an abutment may be provided at or near the distal end of the shuttle for preventing the plurality of stent segments from being advanced beyond the distal end of the shuttle.
- the shuttle may be axially movable relative to the catheter shaft, so that the expandable member may be retracted relative to the shuttle to allow for multiple stent segment deployments.
- the shuttle may be fixed in its position relative to the catheter shaft.
- the sheath may further include at least one valve member at or near its distal end (or elsewhere along the sheath) for selectively retaining at least one stent within the sheath.
- Such a valve member is typically disposed on the sheath and is used for controlling the deployment of one or more stent segments, stent segments or other prostheses.
- the valve member may be distinguished from the abutment on the shuttle described above, in that the abutment is typically located on the shuttle and serves to prevent one or more stent segments, stent segments or other prostheses from being pushed off the distal end of the shuttle, such as with a pusher device.
- a method for delivering a plurality of stent segments to a treatment site involves positioning a distal portion of a stent delivery catheter device at the treatment site and moving a sheath of the catheter device proximally relative to an expandable member on the catheter device, thus allowing at least part of the expandable member to expand against an expandable shuttle of the catheter device to deploy at least one of the plurality of stent segments.
- the at least one stent segment comprises a first plurality of stent segments.
- the method may further include moving the sheath farther proximally to further expose the expandable member to allow it to expand against the expandable shuttle to deploy at least a second plurality of stent segments.
- the method may then involve serially moving the sheath farther proximally to deploy third, fourth, fifth pluralities or any number of subsequent stent segments.
- the method may be used to select any number of stent segments to deploy and to deploy that selected number of stent segments.
- a second number of stent segments may then be selected and deployed, and a third number and so on.
- methods of the present invention provide for selection and deployment of custom length stents. Deployed stents may have different lengths, shapes, coatings, stiffness, strut configurations, geometries or the like.

- Figs. 6A-6D demonstrate a method for delivering a plurality of prostheses at a treatment site, according to one embodiment of the invention.
- Stent delivery devices of the present invention generally include a shuttle for carrying multiple stent segments, so that the stent segments need not be placed on, or advanced directly over, an expandable balloon member of the device.
- the shuttle is disposed over, and at least partly expandable by, an expandable member such as a balloon, to expand and deploy the stent segments.
- the shuttle is positioned outside the expandable member and a sheath, such that when the sheath is withdrawn part of the expandable member is exposed to expand against the shuttle, thus expanding and deploying one or more stent segments.
- the shuttle may be positioned inside the sheath such that withdrawing the sheath allows the expandable member and the shuttle to expand to deploy one or more stent segments.
- stent segments may either be fixed on the shuttle or may be slidably disposed along the shuttle.
- the device may further include a stent pushing member for advancing the stent segments distally along the shuttle and/or an abutment for preventing stent segments from being pushed off the distal end of the shuttle.
- Shuttles of the present invention generally enhance stent delivery by providing for delivery of custom length stents while avoiding direct contact between the stent segments and the expandable balloon, thus reducing the risk of damage to the balloon and/or the stent segments and enhancing ease and accuracy of stent placement at a treatment location.
- delivery of custom length stents it is meant that a number of stent segments may be selected and deployed.
- multiple stents each having multiple stent segments may be disposed along a shuttle.
- a user may choose to deploy a selected number of stent segments of a first stent at a first location in a body lumen by withdrawing a sheath to expose the selected number of segments.
- the user may then choose to deploy a selected second number of stent segments, either from the first stent or from a subsequent stent, at a second location, and so on.
- stents of custom length, and possibly of other custom characteristics such as configuration maybe selected and deployed.
- stents and “stent segments” are used frequently in this application.
- the term “stent” is well known in the art, and some stents are segmented into two or more stent segments. Generally, adjacent stent segments of one stent may be connected, partially connected, breakably connected, or completely separate.
- Methods and apparatus of the present invention are generally used to deliver multiple stents, multiple stent segments or both in a body lumen such as a blood vessel. In various embodiments, for example, multiple stents each having multiple segments, multiple segments of one stent, and/or multiple non- segmented stents may be delivered.
- a stent delivery catheter device 20 is shown, with a distal portion in cross-section.
- the catheter device 20 may be similar to a stent deliver catheter described in U.S. Patent Application Serial No. 10/637713, previously incorporated by reference, although it includes the added feature of a shuttle 21 along which multiple stent segments 32 are disposed.
- stent delivery catheter 20 may suitably include a catheter body 22 comprising a sheath 25 slidably disposed over a shaft 27.
- the expandable member could be any one of a variety of other mechanically, hydraulically, electrically, or otherwise expandable structures known in the mfraluminal catheter arts, such as expandable braids, expandable cages, expandable Mallecott structures, self-expanding structures (including shape memory cages), and the like.

- Stent segments 32 are disposed on shuttle 21, which in turn is disposed on expandable member 24 for expansion therewith, typically being coaxially and slidably received over shaft 27.
- a guidewire tube 34 is slidably positioned through a guidewire tube exit port 35 in sheath 25 proximal to expandable member 24.
- a guidewire 36 is positioned slidably through guidewire tube 34, expandable member 24, and nosecone 28 and extends distally thereof.
- Other designs where a guidewire is received through the entire shaft 27 are also within the present invention.
- a handle or hub 38 is mounted to a proximal end 23 of sheath 25 and includes an actuator 40 slidably mounted thereto for purposes described below.
- An adaptor 42 is mounted to the proximal end of handle 38 and provides a catheter port 44 through which shaft 27 is slidably positioned.
- a flush port 48 is mounted to the side of adaptor 42 through which a fluid such as saline can be introduced into the interior of catheter body 22.
- An annular seal (not shown) in catheter port 44 seals around shaft 27 to prevent fluid from leaking through catheter port 44.
- a clamp such as a threaded collar, can be mounted to catheter port 44 to lock shaft 27 relative to handle 38.
- adaptor 42 is shown separately from handle 38, the structures could be made integral to each other as well.

- Stents 30 or stent segments 32 may be mounted on shuttle 21 in fixed or slidable fashion, in various embodiments, with slidable embodiments often including a stent pushing member for advancing the segments 32. Therefore, Figure 1 depicts only one exemplary embodiment of a stent delivery device and in no way should be interpreted to limit the scope of the invention. [0032] Stent segments 32 are described more fully in U.S. Patent Application Serial No. 10/637713, previously incorporated by reference and Application Serial No. 60/440839, filed January 17, 2003 (Attorney Docket No. 21629-000500), which is incorporated herein by reference.
- each stent segment is about 2-8 mm in length, and up to 10-50 stent segments maybe positioned end-to-end in a line over shuttle 21.
- Stent segments 32 may be in direct contact with each other, but preferably stent segments 32 are spaced apart from each other enough so that each stent segment 32 may be expanded without interfering with any adjacent stent segment(s) 32. Alternatively, separate spacing elements may be disposed between adjacent stent segments 32.
- Such spacing elements may be plastically deformable or self-expanding so as to be deployable with stent segments 32 into the vessel, but alternatively could be configured to remain on shuttle 21 following stent deployment; for example, such spacing elements could comprise elastic rings which elastically expand with balloon member 70 and resiliently return to their unexpanded shape when shuttle 21 is deflated.
- Stent segments 32 are preferably a malleable metal so as to be plastically deformable by expandable member 24 as they are expanded to the desired diameter in the vessel.
- stent segments 32 maybe formed of an elastic or super elastic shape memory material such as Nitinol so as to self-expand upon release into the vessel by retraction of sheath 25.

- Stent segments 32 may have a variety of configurations, mcluding those described in Application Serial No. 60/440839, previously incorporated by reference. Stent segments 32 are preferably completely separate from one another without any interconnections, but alternatively may have couplings between two or more adjacent segments which permit flexion between the segments. As a further alternative, one or more adjacent stent segments 32 may be connected by separable or frangible couplings that are separated prior to or upon deployment, as described in U.S. Application Serial No. 10/306,813, filed November 27, 2002 (Attorney Docket No. 21629-000320), which is incorporated herein by reference.
- delivery catheter 60 may suitably include catheter shaft 27, expandable member 24, sheath 25a and nosecone 28, and may allow for passage of a guidewire 36.
- Stent segments 32 are disposed along a shuttle 21a, and in this embodiment shuttle 21a is disposed over sheath 25a and expandable member 24.
- Shuttle 21a may be composed of any suitable material or combination of materials and may have any suitable length, inner diameter, thickness and the like. Generally, at least part of shuttle 21a will be expandable so that expandable member 24 can expand shuttle 21a to expand and deploy stent segments 32. Shuttle 21 may thus be expandable along its entire length or only along a portion of its length near the distal end. The expandable portion of shuttle 21a may be composed of similar materials to that of the expandable member 24 or alternative materials. In some embodiments, for example, at least part of shuttle 21a may comprise a semi-compliant polymer such as Pebax or Nylon and is configured to resiliently return to its unexpanded shape following expansion.

- the proximal portion has a length of about 100- 125 cm.
- the proximal portion may be constructed of a variety of biocompatible polymers or metals, preferably being stainless steel or Nitinol.
- the distal portion may be a polymer such as PTFE, FEP, polyimide, or Pebax, and is preferably reinforced with a metallic or polymeric braid to resist radial expansion when expandable member 24 is expanded.
- the proximal portion has a smaller transverse dimension than the distal portion to accommodate the added width of a guidewire tube within the vessel lumen, as well as to maximize flexibility and minimize profile.
- the distal portion may have an outer diameter of about 1.0-1.5 mm
- the proximal portion may have an outer diameter of about 0.7-1.0 mm.
- a proximally-facing crescent-shaped opening may be formed between the two tubular members that creates a guidewire tube exit port. Excess space within the crescent- shaped opening may be filled with a filler material such as adhesive.
- shuttle 21 is slidably coupled with catheter 60 to allow it to move axially relative to one or more catheter components.
- Sheath 25a is withdrawn proximally to expose a portion of expandable member 24.
- Expandable member 24 (shown in unexpanded configuration) then expands to contact and expand shuttle 21a which in turn expands and deploys a selected number of stent segments 32.
- stent segments 32 may be expanded and deployed one at a time or in groups to provide custom length stent deployment.
- As sheath 25a is withdrawn farther proximally, more expandable member 24 is exposed, more shuttle 21a is expanded, and additional stent segments 32 are expanded and deployed.
- Catheter 60 may also be retracted relative to shuttle 21 to align expandable member 24 with additional stent segments 32.

- Stent pushing member 82 may be constructed of a variety of biocompatible polymers or metals, preferably being stainless steel or Nitinol.
- annular ridge 86 or other abutment may be included on shuttle 21c to act as a stop to the most distal stent segment 32.
- Such embodiments may also include one or more valves 84 disposed on the inner surface of sheath 25c for allowing a physician to better regulate the number of stent segments 32 that pass through sheath 25c.
- valves are described in copending U.S. Patent Application Serial No. 10/412714, which was previously incorporated by reference.
- Valve 84 also enables the physician to retract stent segments 32 within sheath 25c, thereby creating suitable spacing between segments 32 for deployment without interference between adjacent segments 32.
- a stent delivery catheter 90 includes axially slidable sent segments 32 on a shuttle 21d disposed outside of a sheath 25d.
- a stent pushing member 82 is included in catheter device 90, and shuttle 21d includes a annular ridge 86.
- Sheath 25d is axially slidable over expandable member 24 to selectively expose a desired length of expandable member 24.
- a method for delivering stent segments is shown, though for purposes of clarity no vasculature or other lumen is shown.
- a stent delivery catheter 60 will be advanced through a patient's vasculature or other lumen to a desired location for delivering stent segments 32.
- sheath 25a may be withdrawn or retracted proximally, as shown by the two proximally directed arrows in Figure 6A, to expose at least part of expandable member 24 within shuttle 21 A. Exposed expandable member 24 may then be expanded, as shown in Figures 6B and 6C.
- expandable member 24 contacts and expands an expandable portion of shuttle 21a, which in turn causes one or more stent segments 32 to expand, as shown in Figure 6C.
- stent segments 32 remain expanded and in place, as shown in Figure 6D.
- Shuttle 21a resumes its original shape.
- a physician may then reposition delivery catheter 60 and retract sheath 25a and expandable member 24 further proximally and expand expandable member 24 and shuttle 21a to deploy additional stent segments 32.
- a physician may advanced sheath 25a distally to cover expandable member 24.
- the method may further include advancing stent segments 32 with a stent pushing member, sliding shuttle 21a, and using a valve to control stent advancement, using the catheter embodiment of Fig. 4.
- Various embodiments of the method may be used by adding, subtracting or substituting steps without departing from the scope of the invention.
