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.

First claim

What is claimed is:

1. A system, comprising:
an inner member having a holding region;
wherein the inner member has an elongate slot formed therein;
an expandable implant disposed along the holding region;
wherein the expandable implant has a first length, wherein the elongate slot has a second length, and wherein the second length is greater than or equal to the first length;
a deployment sheath slidably disposed about the inner member;
a rack coupled to the deployment sheath;
a handle coupled to the rack;
wherein the rack extends within the handle;
wherein a distal portion of the rack is designed to extend distally of the handle; and
wherein a proximal portion of the rack is designed to extend proximally of the handle.

2. The system of claim 1 , wherein the handle includes an actuation member designed to engage the rack and designed to axially shift the deployment sheath relative to the inner member.

3. The system of claim 1 , further comprising a pull grip coupled to the proximal portion of the rack.

4. The system of claim 1 , wherein the rack includes a sidewall having a longitudinal slit.

5. The system of claim 1 , wherein the inner member includes a cut portion.

6. The system of claim 1 , further comprising a support member disposed within the deployment sheath.

7. A delivery system, comprising:
an inner member having a holding region;
an expandable implant disposed along the holding region;
a deployment sheath slidably disposed about the inner member, the deployment sheath including a distal region disposed adjacent to the holding region, a proximal region disposed proximally of the holding region, and a rack region;
a handle coupled to the deployment sheath;
wherein the distal region of the deployment sheath has a first outer diameter, wherein the proximal region of the deployment sheath has a second outer diameter, and wherein the first outer diameter is different from the second outer diameter; and
wherein the rack region is designed to extend within the handle, proximally of the handle, and distally of the handle.

8. The delivery system of claim 7 , wherein the first outer diameter is greater than the second outer diameter.

9. The delivery system of claim 7 , wherein the inner member includes an elongate slot.

10. The delivery system of claim 9 , wherein the expandable implant has a first length, wherein the elongate slot has a second length, and wherein the second length is greater than or equal to the first length.

11. The delivery system of claim 9 , wherein a sleeve is disposed adjacent to the elongate slot.

12. The delivery system of claim 11 , wherein a port is defined at a proximal end of the sleeve.

13. The delivery system of claim 11 , further comprising a support member disposed within the proximal region of the deployment sheath.

14. The delivery system of claim 13 , wherein the support member has a distal end positioned adjacent to the sleeve.

15. The delivery system of claim 13 , wherein the support member is free of a lumen.

16. The delivery system of claim 7 , further comprising a pull grip coupled to a proximal end of the rack region.

17. A stent delivery system, comprising:
an inner member having a stent holding region;
a slot formed in the inner member;
a sleeve coupled to the inner member adjacent to the slot;
a stent disposed along the stent holding region;
wherein the stent has a first length, wherein the slot has a second length, and wherein the second length is greater than or equal to the first length;
a deployment sheath slidably disposed about the inner member, the deployment sheath including a distal region disposed adjacent to the stent holding region, a proximal region disposed proximally of the stent holding region, and a rack region;
a support member disposed within the deployment sheath, the support member having a distal end positioned adjacent to the sleeve;
a handle coupled to the deployment sheath; and

wherein the rack region has a distal end disposed distal of the handle, a central portion disposed within the handle, and a proximal end disposed proximal of the handle.
