Abstract
This is a device for capturing and removing bodies or articles from within a vessel, such vessels as may be found in the vascular system or the genital urinary tract. It includes a core wire which has attached at its distal end a plurality of fibers. The core wire may be introduced through a catheter to a selected site and further advanced and "twirled" to engage the offending foreign body. The retriever and its targeted foreign body are then withdrawn using the catheter.
