1. An embolus extractor, comprising:
- an elongate shaft having a proximal end and a distal end;
first and second struts, each strut having a proximal end coupled to the shaft and a distal end coupled to the distal end of the shaft, the struts having a first position and a second position;
wherein in the first position, the distal ends and the proximal ends of the 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, and wherein in the second position the proximal ends of the struts form an open, generally circular mouth that is eccentric with respect to the shaft; and
wherein the stuts can rotate about the elongate shaft.

16. An embolus extractor, comprising:
-
an elongate shaft having a proximal end and a distal end; a first strut having a proximal end and a distal end, the proximal end and the distal end of the strut being coupled to the shaft, the strut having a first position and a second position; wherein in the first position, the distal end and the proximal end of the first strut are spaced at a first distance, and in the second position, the distal end and the proximal end of the first strut are spaced at a second distance being less than the first distance, and wherein in the second position, a proximal length of the first strut defines an open, generally circular mouth that is eccentric with respect to the shaft; and a second strut coupled to the shaft, the second strut having a transverse cross sectional area; wherein the first strut has a transverse cross sectional area greater than the cross sectional area of the second strut. - View Dependent Claims (15, 17, 18, 19, 20, 21, 22)

23. An embolus extractor, comprising:
-
an elongate shaft having a proximal end and a distal end; first and second struts, each strut having a proximal end coupled to the shaft and a distal end coupled to the distal end of the shaft, the struts having a first position and a second position; and a sleeve slidably coupling the proximal ends of the struts to the shaft such that the struts can translate at least in part along the elongate shaft; wherein in the first position, the distal ends and the proximal ends of the 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, and wherein in the second position the proximal ends of the struts form an open, generally circular mouth that is eccentric with respect to the shaft. - View Dependent Claims (24)
