Abstract

An embolus extractor including elongate shaft having a proximal end and a distal end. The embolus extractor may include primary struts coupled to the distal end of the shaft. The struts may define a proximally disposed mouth. Additional secondary struts may be coupled along the elongate shaft to enhance the thrombus containing ability of the embolus extractor.

Claims

1. An embolus extractor, comprising:

an elongate shaft having a proximal end and a distal end;

a plurality of primary struts, each strut having a proximal end and a distal end coupled to the distal end of the shaft; and

the primary struts having a first position and a second position, wherein in the first position, the distal ends and the proximal ends of the primary struts are spaced at a first distance, and in the second position the distal ends and the proximal ends of the struts are spaced at a second distance, the second distance being less than the first distance.
