Abstract

A medical device system includes a catheter, an expandable prosthesis over t he catheter, and a holding material between the catheter and the prosthesis. Th e holding material initially holds the prosthesis over the catheter.

Claims (27)

1. A medical device system, comprising:
a catheter;
an expandable prosthesis over the catheter; and a holding material between the catheter and the prosthesis, the holding material initially holding the prosthesis over the catheter.
2. The system of claim 1, wherein the prosthesis is not completely expanded.
3. The system of claim 1, wherein the catheter comprises a lumen in fluid communication with the holding material.
4. The system of claim 1, further comprising a heatable wire extending between the catheter and the prosthesis.
5. The system of claim 1, wherein the exterior surface of the prosthesis is substantially exposed.
6. The system of claim 1, wherein the prosthesis is capable of exerting a radial, expansion force.
7. The system of claim 1, wherein the prosthesis is self expandable.
8. The system of claim 1, wherein the prosthesis is separable from the catheter.
9. The system of claim 1, wherein the prosthesis comprises a first portion separable from the catheter, and a second portion inseparable from the catheter.
10. The system of claim 9, wherein the prosthesis further comprises a detachable portion between the first and second portions.
11. The system of claim 9, wherein the prosthesis further comprises a structurally weakened portion between the first and second portions.
12. The system of claim 9, wherein the prosthesis further comprises a degradable portion between the first and second portions.
13. The system of claim 1, wherein the prosthesis comprises a wire having two portions with different electrical resistance.
14. The system of claim 1, further comprising two axially movable sleeves initially holding end portions of the prosthesis to the catheter.
15. The system of claim 1, wherein the prosthesis is a stent.
16. The system of claim 1, wherein the prosthesis a stent-graft.
17. The system of claim 1, wherein the holding material is an adhesive.
18. The system of claim 1, free of a constraining device extending over substantially a whole length of the prosthesis.
19. The system of claim 1, free of an inflatable balloon between the catheter and the prosthesis.
20. A method of using a medical device system, the method comprising:
positioning the system at a predetermined site, the system comprising:
a catheter;
an expandable prosthesis over the catheter; and a holding material between the catheter and the prosthesis, the holding material initially holding the prosthesis over the catheter; and releasing the prosthesis from the catheter.
21. The method of claim 20, comprising exposing the holding material to a condition that modifies the hold between the catheter and the prosthesis.
22. The method of claim 21, wherein the condition is selected from a group consisting of a change in temperature, a change in pH, and a change in pressure.
23. The method of claim 20, comprising contacting the holding material with a fluid that releases the hold between the catheter and the prosthesis.
24. The method of claim 23, wherein the fluid is introduced through a lumen in fluid communication with the holding material.
25. The method of claim 20, wherein the prosthesis is released from the catheter adjacent to an aneurysm.
26. The method of claim 20, comprising applying monopolar radiofrequency energy.
27. The method of claim 20, comprising applying bipolar radiofrequency energy.
