Claim 0:
1. An endoscopic snare with asymmetric corners comprises:
a tube having a distal end and a proximal end, a wall of the tube defining a lumen;
a length of control wire extending through a portion of the lumen; and
a shaped loop having a distal end of the loop and a proximal end of the loop, the distal end of the loop being shaped to expand as the distal end of the loop exits the distal end of the tube, and the proximal end of the loop being coupled with the length of control wire, the loop having at least two corners arranged such that the at least two corners exit the lumen after the distal end of the loop exits the tube and before the proximal end of the loop exits the tube, the at least two corners being comprised of at least a first corner on a first side of the loop and a second corner on a second side of the loop, the second side being opposite of the first side, and the second corner being closer to the proximal end of the loop than the first corner, such that the first side of the loop and the second side of the loop are asymmetric, and wherein each of the at least two corners comprises a first bend in a first bend angular direction, a second bend in a second bend angular direction, opposite of the first bend angular direction, and a third bend in a third bend angular direction opposite of the second bend angular direction, arranged such that each of the at least two corners extends outwardly from an imaginary line extending from a central longitudinal axis of the tube, when the loop is extended from the tube.
