<p>A device for retrieving foreign bodies, such as a vaso-occlusive coil or other articles from within vessels such as those of the cardiovascular system. Two small snare coils (60, 62) are joined at their distal ends (68, 70) to form a loop. The proximal ends of the coils are attached to one or more elongated actuator members (20, 22). The loop size is adjusted by manipulation of one or more of the proximal ends (26, 44) of the elongated actuator members. This retrieval device may be used to ensnare and either reposition or remove foreign bodies within a vessel lumen.</p> |
