Medical snare

A snare, comprising:

• an outer sheath defining an outer sheath lumen;
• an elongate member disposed in the outer sheath lumen and having a longitudinal axis and at least one elongate member lumen;
• a capture member disposed and axially movable within the at least one elongate member lumen, the capture member defining a capture loop having a throat region, a first extended portion along a plane that is perpendicular to the longitudinal axis of the elongate member, and a second portion extending from the first portion and along a plane disposed at a non-parallel and non-orthogonal angle to the longitudinal axis of the elongate member;
• and
• a threader member disposed and axially movable within the at least one elongate member lumen, the threader member defining a threader loop.

A snare, comprising:

• an outer sheath defining an outer sheath lumen;
• an elongate member having a longitudinal axis and disposed and axially movable within the outer sheath lumen, the elongate member having an elongate member proximal end, an elongate member distal end, and an elongate member main body extending between the elongate member proximal end and the elongate member distal end and having at least one elongate member lumen extending from the elongate member proximal end to the elongate member distal end;
• a capture member disposed and axially movable within the at least one elongate member lumen, the capture member having a capture member proximal end and a capture member distal end, the capture member distal end defining a capture loop having a throat region, a first portion extending along a plane that is perpendicular to the longitudinal axis of the elongate member, and a second portion extending from the first portion, the second portion including the capture member distal end and extending along a plane disposed at a non-parallel and non-orthogonal angle to the longitudinal axis of the elongate member;
• a threader member disposed and axially movable within the at least one elongate member lumen, the threader member having a threader member proximal end and a threader member distal end, the threader member distal end defining a threader loop, the threader member extending through the capture loop at the first portion;
• and
• a handle attached to the elongate member, the handle including a plunger attached to the threader member.
