Abstract

A medical device for placing a very small embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal tip for retaining a headpiece with an attached embolic coil such that when the catheter is pressurized with a fluid the distal tip of the catheter expands outwardly to release the headpiece and coil at the preselected position.
