Abstract

This is a surgical device usually delivered through an intravascular catheter. It is designed to pierce and remove emboli often found in tortuous vasculature. The device includes several sections. The device has a core element. Placed around the distal end of the core wire is a collapsible but self expanding embolism collection assembly. That collector assembly is typically joined to the core wire at its distal end. The collector assembly may have a generally conical distal portion when expanded and may have a proximal section having varied purposes, e.g. for centering the collector assembly in the vascular lumen. The assembly further may have an actuator which permits the collector assembly to expand after deployment.
