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. The headpiece has a passageway which extends through the headpiece to permit air to be purged from the catheter prior to insertion of the catheter into the vessel.
