Patent ID: 7799052

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 tubular pusher member having a wall and a lumen extending therethrough and having proximal and distal ends and being slidably disposed within the lumen of the deployment catheter, the lumen having a central axis; an embolic device having a retaining ring at the proximal end thereof; an engagement member extending from the distal end of the pusher member and having an aperture extending through the distal end thereof, said engagement member extending through said retaining ring; a kicker tongue formed integrally from the wall of the tubular pusher member as a distal projection and having an aperture through the distal end thereof and exhibits the characteristic of being normally biased parallel to the central axis of the lumen of the pusher member and is deflected in a direction toward the central axis for engagement with said retaining ring of said embolic device so that it contacts said retaining ring to thereby urge said retaining ring of said embolic device to be lifted off of said engagement member; and, an elongated detachment member having a distal end and 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 and through the aperture of the kicker tongue such that when the detachment member is pulled proximally the distal end of the detachment member is withdrawn from the aperture of the engagement member and said kicker tongue, and said kicker tongue lifts said retaining ring on said embolic device off of said engagement member to thereby release the embolic device from said pusher member.
