Patent ID: 7371252

Claim:
A vasooclusive embolic device deployment system for use in placing an embolic device at a predetermined site within a vessel comprising: an elongated flexible deployment catheter having a lumen extending therethrough and having proximal and distal ends; an elongated pusher member having a lumen extending therethrough and having proximal and distal ends and being slidably disposed within the lumen of the deployment catheter; an embolic device having a retaining ring at the proximal end thereof; a resilient engagement member extending from the distal end of the pusher member and having an aperture extending through the distal end thereof, said engagement member having a normally biased position which extends in a plane generally parallel to the central axis of the lumen of said pusher member but being deflected out of said plane toward the central axis of the lumen of the pusher member and extending through said retaining ring; a support member extending from the distal end of the pusher member and being generally parallel to the plane of said retaining ring to thereby support said retaining ring during the withdrawal of said engagement member; and, an elongated detachment member extending from a position proximal of the proximal end of the pusher member, through the lumen of the pusher member and through the aperture of the engagement member such that when the detachment member is pulled proximally from the pusher member to the distal end of the detachment member through the aperture of the engagement member such that when the detachment member is pulled proximally from the pusher member to the distal end of the detachment member is withdrawn from the aperture of the engagement member and said engagement member returns to its normally biased position thereby causing said engagement member to withdraw from the retaining ring of said embolic device to thereby release the embolic device.
