ABSTRACT:
A device for retrieving foreign bodies, such as a vasoocclusive coil or elements, from within vessels such as those of the cardiovascular system includes a tubular member and a flexible wire that extends axially through the tubular member with its distal end extending out the distal end of the tubular member and looped back and affixed to the distal end of the tubular member to form a loop whose size may be adjusted by axial movement of the wire relative to the tubular member and which may be used to ensnare the foreign bodies and remove them from the vessel.
