AI Technical Summary
Current endovascular thrombectomy devices have a lower success rate in removing chronic thrombus due to its transformation into a tougher fibrin or collagen structure, which is firmly adhered to the vein wall, and venous synechiae can prevent optimal treatment by balloon angioplasty or stenting.
A device comprising an elongate control member with an expandable basket coupled to its distal portion, the basket having a plurality of braided filaments defining an interior cavity and configured to capture and remove chronic thrombus from blood vessel lumens, with legs that position the basket independently of the control member's path to maintain contact with the vessel wall.
The device effectively captures and removes chronic thrombus, even in curved vessels, by maintaining contact with the vessel wall and providing mechanical decoupling between the basket's proximal edge and the control member, thereby enhancing the success rate of thrombectomy procedures.
