Abstract

The present invention is directed to a stent assembly for use in temporarily securing a surgical component during a surgical procedure. The stent assembly includes a catheter assembly having at least one primary passageway extending there through. The stent assembly further includes a securing assembly for exerting a force against the surgical component for temporarily securing the surgical component during the surgical procedure. The securing assembly includes a portion that extends through the at least one primary passageway. The catheter assembly may include a secondary passageway. The secondary passageway is adapted to receive a guide device therein. The securing assembly has a retracted position and an extended position. The securing assembly exerts a force against the surgical component while the securing means is in the extended position. The securing assembly may contain a coating which increases the gripping force of the securing assembly.

Claims

1. A stent assembly for use in temporarily securing a surgical component during a surgical procedure, said stent assembly comprising:

a catheter assembly having at least one primary passageway extending there through; and

securing means for exerting a force against the surgical component for temporarily securing the surgical component during the surgical procedure, wherein said securing means includes a portion that extends through said at least one primary passageway.

2. The stent assembly according to claim 1, wherein said catheter assembly includes a secondary passageway, wherein said secondary passageway is adapted to receive a guide device therein.

3. The stent assembly according to claim 1, wherein said securing means has a retracted position and an extended position.

4. The stent assembly according to claim 1, wherein said stent assembly may be advanced through a vessel in order to selectively position said stent assembly.

5. The stent assembly according to claim 4, wherein said stent assembly is advanced through the vessel in order to selectively position said stent assembly while said securing means is in said retracted position.

6. The stent assembly according to claim 4, wherein said stent assembly is inserted into the vessel via an axillary incision, a brachial incision, or a femoral or a common iliac arteriotomy.

7. The stent assembly according to claim 3, wherein said securing means exerts a force against said surgical component while said securing means is in said extended position.

8. The stent assembly according to claim 1, wherein said stent assembly is used in the repair of an aneurysm.

9. The stent assembly according to claim 1, wherein said stent assembly is used to hold a surgical component against a vessel wall, wherein the surgical component may be fastened to the vessel wall to avoid leakage.

10. The stent assembly according to claim 1, wherein said securing means for exerting a force against said surgical component during said surgical procedure further comprises a coating which increases the gripping force of said securing means.

11. A stent assembly for use in temporarily securing a surgical component during a surgical procedure, said stent assembly comprising:

a catheter assembly having a first primary passageway and a second primary passageway extending there through; and

securing means for exerting a force against the surgical component for temporarily securing the surgical component during the surgical procedure, wherein said securing means includes a portion that extends through said first primary passageway and said second primary passageway.

12. The stent assembly according to claim 11, wherein said catheter assembly includes a secondary passageway, wherein said secondary passageway is adapted to receive a guide device therein.

13. The stent assembly according to claim 11, wherein said securing means has a retracted position and an extended position.

14. The stent assembly according to claim 11, wherein said stent assembly may be advanced through a vessel in order to selectively position said stent assembly.

15. The stent assembly according to claim 14, wherein said stent assembly is advanced through the vessel in order to selectively position said stent assembly while said securing means is in said retracted position.

16. The stent assembly according to claim 14, wherein said stent assembly is inserted into the vessel via an axillary incision, a brachial incision, or a femoral or a common iliac arteriotomy.

17. The stent assembly according to claim 13, wherein said securing means exerts a force against said surgical component while said securing means is in said extended position.

18. The stent assembly according to claim 11, wherein said first primary pasasgeway and said second primary passageway are located adjacent to one another.

19. The stent assembly according to claim 11, wherein said stent assembly is used to hold a surgical component against a vessel wall, wherein the surgical component may be fastened to the vessel wall to avoid leakage.

20. The stent assembly according to claim 11, wherein said securing means for exerting a force against said surgical component during said surgical procedure further comprises a coating which increases the gripping force of said securing means.
