Patent ID: 7875038

Claim:
A medical retrieval device comprising: a proximal handle; a sheath extending distally from the handle and including a lumen extending therethrough from a distal end of the sheath to a proximal end of the sheath; only two opposing loops comprised of a single piece of unitary material, the loops having a first position in which the loops are collapsed within the lumen of the sheath and a second position in which the loops are extended from the distal end of the sheath and out of the lumen, the loops being joined at a base and unattached to each other at their distal ends, the loops being moveable between an open position and a closed position with the loops being closer together at their distal ends when in the closed position than when in the open position to allow capture and release of material; and an elongate member having a first portion, an intermediate portion, and a second portion, the intermediate portion disposed between the first portion and second portion, wherein the intermediate portion is configured to pass through the two opposing loops proximate to the base of the two opposing loops.
