Abstract

An embolic coil retrieval system for retrieving or repositioning an embolic coil within the vasculature of the human body which is comprised of a very small embolic coil retriever having a jaw member with major and minor teeth which form pockets for grasping an embolic coil when the jaw member is closed.

Claims

1. A method for capturing an embolic coil in a vessel of the body, said method comprising the steps of:

providing an embolic coil retrieval system comprising a sheath, an embolic coil retriever comprising a cylindrical member, a jaw member including a first jaw, a second jaw, and a third jaw attached to said cylindrical member, a plurality of teeth attached to said jaw member, and an actuator wire attached to said cylindrical member;

inserting said embolic coil retrieval system into the vasculature of the human body;

pushing said actuator wire distally through said sheath causing said embolic coil retriever to exit a distal end of said sheath thereby allowing said jaws of said embolic coil retriever to open;

moving said embolic coil retriever distally to align said jaws of said embolic coil retriever with an embolic coil;

pushing said sheath distally causing said jaws of said embolic coil retriever to close around said embolic coil; and

,

removing said embolic coil retrieval system from a vessel of the body.

2. A method for capturing a medical device in a vessel of the body, said method comprising the steps of:

providing a medical device retrieval system comprising a sheath, a medical device retriever comprising a cylindrical member, a jaw member including a first jaw, a second jaw, and a third jaw attached to said cylindrical member, a plurality of teeth attached to said jaw member, and an actuator wire attached to said cylindrical member;

inserting said medical device retrieval system into the vasculature of the human body;

pushing said actuator wire distally through said sheath causing said medical device retriever to exit a distal end of said sheath thereby allowing said jaws of said medical device retriever to open;

moving said medical device retriever distally to align said jaws of said medical device retriever with a medical device;

pushing said sheath distally causing said jaws of said medical device retriever to close around said medical device; and

,

removing said medical device retrieval system from a vessel of the body.
