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 retrieval end having one or more compressed states and an expanded state, the retrieval end adopting the expanded state when the retrieval end is deployed into a subject's internal body space, the retrieval end having a mouth through which an object can be passed into an interior space within the retrieval end when the retrieval end is in the expanded state, the mouth being adjustable between an opened state and a closed state; wherein when at least a portion of the retrieval end of the inner sheath is transitioned to a compressed state following capture of the object, the retrieval end exerts an inward force that at least partially collapses or compresses the object.
