Abstract

Disclosed are systems, methods, and devices for percutaneous retrieval of objects, such as endovascular devices, from a subject's internal body space. The present inventions have vascular, non-vascular (gastrointestinal), and surgical (laproscopic) applications. The inventions include the use of 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 so that the object can be enclosed within the interior space after passing through the mouth of the retrieval end.
