Patent ID: 8801748

Claim:
A medical device for removing an obstruction from a blood vessel, the medical device comprising: a main bundle comprising a group of wires having a first end and a second end; a capturing portion formed by the group of wires and having a translating surface adjacent to a capturing surface, the translating surface having an open proximal end and the capturing surface having a permeable distal end, where the group of wires forming the capturing surface comprise a crossing mesh pattern having a plurality of interference points in the crossing mesh pattern where adjacent wires cross, where the plurality of interference points selectively interfere to limit radial expansion of the capturing surface upon axial compression of the capturing surface; where the capturing portion is formed from the group of wires such that the group of wires diverges from the second end of the main bundle to form the permeable distal end, the group of wires extend back in a proximal direction to form the capturing surface, the translating surface, and open proximal end about the main bundle; and where upon axial compression of the capturing surface the interference points of the crossing mesh engage to limit radial expansion of the capturing surface.
