Abstract

An endovascular conduit device and method for use during cardiac lead extraction and other vascular procedures is presented. The endovascular conduit device includes an outer-sheath, a conduit member, a lumen member, and an inflation member to control the flow of fluid within the conduit member. The endovascular conduit device may be positioned intravascularly as cardiac lead extraction or other procedures are performed. If necessary, as in the case of a vascular tear, the endovascular conduit device further includes expandable members that are activated to allow blood to be forced into the channel of the conduit member. Blood may then be contained and directed safely to bypass the area of vessel injury. In doing so, a catastrophic circulatory collapse or shock is prevented.

Claims

1. An endovascular conduit device comprising:

an outer-sheath having proximal and distal portions;

a conduit member partially disposed within the distal portion of the outer-sheath, the conduit member having a proximal portion and at least two distal portions, and further comprising at least one expandable member disposed within the proximal portion and the distal portions;

a lumen member disposed within the conduit member, the lumen member extending proximally from the proximal portion of the outer-sheath through the distal portions of the conduit member; and

an inflation member disposed within one distal portion of the conduit member, the inflation member for use to control the flow of fluid within the conduit member.

2. The device of claim 1, wherein the conduit member is comprised of a flexible material to allow for the inflation and deflation of the at least one expandable member.

3. The device of claim 1, wherein the conduit member is formed comprised of non-thrombogenic materials.

4. The device of claim 1, wherein the lumen member includes an inflation hub to facilitate the inflation and deflation of the at least one expandable member to create a seal and contain fluid within the conduit member.

5. The device of claim 4, wherein the at least one expandable member allows for the maneuverability of at least one medical instrument outside an exterior portion of the lumen member without compromising the seal.

6. The device of claim 4, wherein the inflation hub is disposed to the proximal portion of the lumen member.

7. The device of claim 1, wherein the proximal portion of the outer-sheath includes a control valve to prevent the leakage of air and fluid from entering the conduit member.

8. The device of claim 1, wherein the conduit member includes at least one guide-wire member.

9. The device of claim 8, wherein the at least one guide-wire member extends proximally from the proximal portion of the lumen member through the distal portions of the conduit member.

10. The device of claim 1, wherein the expandable member is arranged around the conduit member in a spiral manner.

11. An endovascular conduit device comprising:

an outer-sheath having proximal and distal portions;

a conduit member partially disposed within the distal portion of the outer-sheath, the conduit member having a proximal portion and at least two distal portions, and further comprising at least one expandable member spirally disposed within the proximal portion and the distal portions; and

a lumen member disposed within the conduit member, the lumen member extending proximally from the proximal portion of the outer-sheath through the distal portions of the conduit member.

12. The device of claim 11, wherein the conduit member is comprised of a flexible material to allow for the inflation and deflation of the at least one expandable member.

13. The device of claim 11, wherein the conduit member is comprised of non-thrombogenic materials.

14. The device of claim 11, wherein the lumen member includes an inflation hub to facilitate the inflation and deflation of the at least one expandable member to create a seal and contain fluid within the conduit member.

15. The device of claim 14, wherein the at least one expandable member allows for the maneuverability of at least one medical instrument outside an exterior portion of the lumen member without compromising the seal.

16. The device of claim 14, wherein the inflation hub is disposed to the proximal portion of the lumen member.

17. The device of claim 11, wherein the proximal portion of the outer-sheath includes a control valve to prevent the leakage of air and fluid from entering the conduit member.

18. The device of claim 11, wherein the conduit member includes at least one guide-wire member.

19. The device of claim 18, wherein the at least one guide-wire member extends proximally from the proximal portion of the lumen member through the distal portions of the conduit member.

20. A method for utilizing an endovascular conduit device comprising the steps of:

inserting a conduit member having a proximal portion and at least two distal portions, and further comprising at least one expandable member disposed within the proximal portion and the distal portions, into an outer-sheath having proximal and distal portions;

advancing at least one guide-wire member into the proximal portion of a lumen member disposed within the conduit member through the distal portions of the conduit member;

introducing an inflation means into the at least one expandable member through an inflation hub disposed to the proximal portion of the lumen member to create a seal and contain fluid within the conduit member; and

actuating an inflation member disposed within one distal portion of the lumen member to control the flow of the fluid within the conduit member.

21. The method of claim 20, further comprising the steps of inserting the proximal portion of the lumen member into a subclavian vein;

inserting one distal portion into a superior vena cava; and

inserting one distal portion into a right atrium.

22. The method of claim 20, further comprising the steps of inserting the proximal portion of the lumen member into a subclavian vein;

inserting one distal portion into a superior vena cava; and

inserting one distal portion into a pulmonary artery.

23. The method of claim 20, wherein the conduit member is used in a cardiac lead extraction procedure.

24. The method of claim 20, wherein the at least one expandable member allows for the maneuverability of at least one medical instrument outside an exterior portion of the lumen member without compromising the seal.
