Abstract

Medical systems and related methods are disclosed. In some embodiments, the medical systems include an inner tubular member defining an aperture and an outer tubular member at least partially surrounding the inner tubular member. The inner and outer tubular members can be arranged such that an implantable medical endoprosthesis can be disposed therebetween.

Claims

1. A system, comprising:

an outer tubular member defining a lumen;

an inner tubular member slidably disposed within the lumen of the outer tubular member;

an elongate slot formed in the inner tubular member;

a non-tubular support member disposed in the lumen of the outer tubular member;

a self-expanding stent disposed between the outer tubular member and the inner tubular member;

wherein the elongate slot has a length greater than or equal to the length of the self-expanding stent;

a rack member coupled to the outer tubular member;

a handle coupled to the outer tubular member, the handle including an actuation member capable of engaging the rack member; and

wherein the outer tubular member is configured to move relative to the inner tubular member and the support member.

2. The system of claim 1, wherein in the rack member includes a sidewall, and wherein the sidewall includes a longitudinal slit.

3. The system of claim 1, wherein the actuation member includes a wheel configured to engage the rack.

4. The system of claim 1, wherein the inner tubular member includes at least one flexible portion.

5. The system of claim 4, wherein the at least one flexible portion includes a cut portion.

6. The system of claim 5, wherein the cut portion includes a plurality of cuts, wherein the plurality of cuts are independent of one another, and wherein the plurality of cuts extend substantially around the inner tubular member.

7. The system of claim 6, wherein at least one of the plurality of cuts further comprise an interrupted spiral, a continuous spiral or both.

8. The system of claim 4, wherein the inner tubular member further comprises a first flexible portion and a second flexible portion, wherein the first flexible portion includes a continuous spiral and second flexible portion includes an interrupted spiral.

9. The system of claim 8, wherein the flexibility of the interrupted spiral is different from the flexibility of the continuous spiral.

10. The system of claim 1, wherein support member is longitudinally fixed relative to the outer member.

11. The system of claim 1, wherein the support member retracts away from the self-expanding stent during deployment of the self-expanding stent.

12. A system comprising:

a self-expanding stent covering member;

an inner member disposed within the covering member, wherein the inner member includes a distal region;

wherein the inner member has an elongate slot formed therein;

a self-expanding stent disposed along the distal region;

wherein the elongate slot has a length greater than or equal to the length of the self-expanding stent;

a non-tubular support member disposed within the inner member;

a port, wherein the port is disposed between the covering member and the inner member, wherein the port is positioned proximal to a distal end of the inner member;

a rack member coupled to the covering member, the rack member fixed to the support member;

a handle coupled to the covering member, the handle including an actuation member capable of engaging the rack member;

wherein the covering member and the support member are configured to move relative to the port.

13. The system of claim 12, wherein the elongate slot is positioned distal to the port.

14. The system of claim 13, wherein the inner member includes at least one flexible portion and wherein the at least one flexible portion includes a cut portion.

15. The system of claim 14, wherein the at least one flexible portion is positioned distal, proximal or both distal and proximal the slot.

16. The system of claim 15, wherein the slot is a longitudinally extending slot.
