Patent ID: 7371251

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 which takes the form of an embolic coil defining a central lumen extending between proximal and distal sections of the coil, a stretch resistant member having first and second ends, said first end of the stretch resistant member is attached to the distal section of the coil and the second end of the stretch resistant member is attached to a retaining ring; an engagement member fixedly attached to 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; 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engagement member such that when the detachment member is pulled proximally the distal end of the detachment member is withdrawn from the aperture of the engagement member to thereby release the embolic device.
