Abstract

Disclosed are systems, methods, and devices for percutaneous retrieval of objects, such as endovascular devices, from an internal body space. The present inventions have vascular, non-vascular (gastrointestinal), and surgical (laproscopic) applications. The inventions include a a wire woven distal end that is formed from wires and includes a substantially cylindrical main body section comprising a leading end, a trailing end, and a middle portion extending between the leading end and the trailing end and defining a longitudinal axis of the main body section, and a flare defining a mouth of the wire woven distal end that projects circumferentially from the leading end of the main body section, wherein when at least a portion of the retrieval end is transitioned to a compressed state following capture of an object, the retrieval end exerts an inward force that at least partially collapses or compresses the object.
