Exterior stent and its use
View Patent ↗A stent apparatus and its use is provided comprising a substantially tubular member with an inside surface and an outside surface; and a securing element for securing the tubular member to the exterior of a body lumen. The method for implanting the stent to the exterior of a body lumen comprises providing for an exterior stent, inserting the stent around a desired location on the exterior of the lumen, and providing for controlled expansion of the lumen such that it contacts the stent sufficiently to secure it to the lumen.
1. A method of supporting a body lumen comprising the steps of:
a) providing a stent having an interior layer and an exterior layer, said interior layer having a securing means thereon;
b) placing said stent around the exterior of a body lumen;
c) expanding said lumen into contact with said securing means, thereby securing the lumen to the securing means.
2. A method of supporting a body lumen comprising the steps of:
a) providing a stent having an interior layer and an exterior layer, said interior layer having a securing means thereon;
b) placing said stent around the exterior of a body lumen;
c) contacting the interior layer of said stent to said lumen, thereby securing the lumen to the securing means.
3. A method of support as in claim 1 or 2 wherein:
the sent covers less than the total circumference of the lumen.
4. A method of support as in claim 1 or 2 wherein:
the stent comprises a biologically inert material.
5. A method of support as in claim 4 wherein:
the stent further comprises a shape-memory material.
6. A method of support as in claim 1 or 2 wherein:
the stent comprises a biologically active material.
7. A method of support as in claim 1 or 2 wherein:
the stent comprises resorbable material.
8. A method of support as in claim 1 or 2 wherein:
the stent comprises a radioactive element for delivering radiation directly to the lumen.
9. A method as in claim 1 or 2 wherein:
the stent is porous.
10. A method of support as in claim 1 or 2 wherein:
the stent is a single unified member.
11. A method of support as in claim 1 or 2 wherein:
the stent comprises at least two members flexibly joined together.
12. A method of support as in claim 1 or 2 wherein:
the stent is bifurcated.
13. A method of support as in claim 1 or 2 wherein:
the stent is further secured by a barb.
14. A method of support as in claim 1 or 2 wherein:
the stent is secured by a hook.
15. A method of support as in claim 1 or 2 wherein:
the stent is secured by an adhesive.
16. A method of support as in claim 1 or 2 wherein:
the stent comprises a braided material.
17. A method of support as in claim 1 or 2 wherein;
the support is substantially composed of resorbable material.
18. A method of support as in claim 1 or 2 wherein:
the stent is further secured by sutures.
19. A method of support as in claim 1 or 2 further comprising the step of:
locking the stent onto the lumen to prevent it from slipping.
20. A method of support as in claim 1 or 2 further comprising:
applying a reinforcing layer for strengthening the stent.
21. The method of claim 2 wherein said step of contacting the interior layer of said stent to said lumen comprises ratcheting said stent.
22. The method of claim 2 wherein said step of contacting the interior layer of said stent to said lumen further comprises compressing said stent into said lumen.
23. The method of claim 1 wherein said step of expanding said lumen into contact with said securing means further comprises dilating said lumen with a balloon device.
