Patent ID: 7811305

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 proximal end, a retaining ring being disposed at the proximal end thereof; an elongated 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 member which takes the form of a spring member having a proximal end, a distal end and a central lumen extending therethrough, the proximal end of said spring member being attached to the distal end of the pusher member and positioned such that the elongated engagement member extends through the central lumen of the spring member, the distal end of said spring member engaging said retaining ring of said embolic device; 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engagement member such that when the detachment member is pulled proximally the distal end of the detachment member is withdrawn from the aperture of the engagement member and said kicker member lifts said retaining ring of said embolic device off of said engagement member to thereby release the embolic device from said pusher member.
