VENOUS CLOT BASKET

摘要

A system for removing a blood clot from a blood vessel or vein is provided. The system includes a plurality of support members that can be expanded to define a basket. The support members include a mesh portion at their distal ends. The system includes a first wire attached to the proximal end of the basket defined by the support members and a second wire attached to a distal end of the basket. The second wire extends through the middle of the basket when the basket is in the expanded condition. The width of the basket can be adjusted by adjusting the second wire relative to the first wire, and the location of the basket can be adjusted by adjusting the first wire. The basket is delivered distally beyond the blood clot, where it is expanded outward. The blood clot is captured by translating the basket proximally.

主权项

1. A system for removing a blood clot from a blood vessel, the system comprising:
a tube member having a proximal end and a distal end, the tube member having a lumen formed through the proximal and distal ends, the lumen defining a longitudinal axis therealong; a first support member having a proximal end and a distal end, the first support member having a first mesh portion at the distal end thereof; a second support member having a proximal end and a distal end, the second support member having a second mesh portion at the distal end thereof; a first wire extending through the lumen, the first wire being attached to the proximal ends of the first and second support members; a second wire extending through the lumen, the second wire being attached to the distal ends of the first and second support members; wherein the first and second support members define a basket therebetween when the first and second support members are expanded from the second wire; wherein the second wire is configured for adjusting the basket between an expanded state and a compressed state; wherein the first wire is configured for adjusting the longitudinal location of the basket; and wherein the second wire extends within the basket defined by the expanded first and second support members when the basket is in the expanded state.
