Small vasculature clot pinching

Abstract

A clot removal assembly for removing a clot from a vessel that includes a delivery catheter, a clot retrieval device, and a valve assembly is presented herein. In some examples, the clot retrieval device can include a cage structure and a shaft, and the cage structure can be configured to pinch a clot. A portion of the shaft extends through the delivery catheter. In some examples, the valve assembly can include a distal valve, a main body portion, a distal body portion, and a moveable head shell. The distal valve can be configured to engage the proximal region of the delivery catheter. In some examples, the distal body portion can include a plurality of grooves, and the moveable head can be configured to ratchet proximally over the plurality of grooves to thereby maintain tension on the shaft.
