A thrombus collection device for removing occluded thrombus from a blood vessel

摘要

The thrombus collection device 1 comprises an externally expandable member 2 comprising a plurality of expandable segments 26 and a means for facilitating the recovery of blood flow through the thrombus immediately after deployment of the thrombus collection device 1 at the occlusion site Which has an internal expandable member (3) for the distal end of the elongate shaft (6). The outer member 2 and the inner expandable member 3 include a folded configuration for delivery and an enlarged configuration for thrombus recovery, flow recovery and fragmentation protection. The proximal radiopaque markers 82 are located at the distal end of the struts 20 of the outer member 2 immediately proximal to the two proximal crown 81. This position is advantageous because it represents the beginning of a fully enlarged diameter of the device, which is part of the most desirable device for deployment under the thrombus for optimal gripping of the thrombus.
