1. An embolic coil retrieval system for capturing an embolic coil in a vessel of the body, said embolic coil retrieval system comprising:
- a sheath which takes the form of a flexible elongated tube with a lumen extending therethrough, said sheath has a proximal section and a distal section;
an embolic coil retriever comprising a cylindrical member having a proximal section, a distal section, and a lumen extending therethrough, said embolic coil retriever also comprising a jaw member including a first jaw, a second jaw, and a third jaw, each jaw takes the form of a longitudinal portion of an elongated tubular member, each jaw has a proximal end, a distal end, a first longitudinal edge, and a second longitudinal edge, said proximal ends of said jaws are attached to the distal section of said cylindrical member, two of said jaws are biased outwardly away from a longitudinal axis of said elongated tubular member, said embolic coil retriever further comprising a plurality of teeth each having a base, each tooth takes the form of a generally triangular member, and said base of each tooth is attached to said jaw member; and
, an actuator wire having a proximal end and a distal end, said wire is slideably disposed within the lumen of said sheath, and said distal end of said wire is attached to the proximal section of said cylindrical member.
