Patent ID: 8628540

Claim:
A snare device for capturing an object, comprising: a wire of memory shaped material shaped to define at least a first loop in a first plane and a second loop in a second plane so as to define a first region between said first and second loops, said wire being movable relative to a hollow member such that said first and second loops are deployable from and retractable into said hollow member; and a locking wire translatable through at least one of said first and second loops after an object is encircled or enveloped by said first and second loops, so as to capture said object within said first region; wherein: said first region tightens around said object as said first and second loops are retracted into said hollow member; and when said wire of memory shaped material is deployed from said hollow member, the first plane is angled relative to an axis of the hollow member or said locking wire by an angle α ranging from 120° to 170°, and the second plane is angled relative to the first plane by an angle β ranging from 10° to 60°.
