Patent ID: 7377932

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; an engagement member fixedly attached to the distal end of the pusher member and having an aperture extending through the distal end portion thereof, the distal end portion of said engagement member that defines the aperture extending through said retaining ring; 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engagement member such that when the detachment member is pulled proximally the distal end of the detachment member is withdrawn from the aperture of the engagement member to thereby release the embolic device.
