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.
Claims37
An embolectomy device comprising:
- a core wire element having a distal end and a proximal end and a longitudinal axis, and
- an embolism collector element comprising at least one spirally wound, superelastic alloy ribbon, and
- an actuator comprising a cylindrical member fixedly attached to the embolism collector element,
- wherein said collector element has a first deployment shape adjacent said core wire element when said actuator is in a first deployment position and a second expanded shape when said actuator is in a second deployment position,
- said second expanded shape comprising a trailing conical collector section having a distal end that is fixedly attached to said core wire element.
