Claim 0:
1. A detachment system for delivering an implantable medical device to a target location of a body vessel, the detachment system comprising:
a tubular body and a distal tube disposed on the end of the tubular body, wherein a lumen extends through the tubular body and the distal tube;
a loop wire comprising a first end affixed to the tubular body and comprising a loop opening positioned approximate a distal end of the distal tube;
a pull wire extending through the lumen;
a hook wire extending radially through a sidewall of the distal tube and into the lumen, the hook wire positioned around a pull wire portion of the pull wire and tensioned such that the pull wire portion abuts the distal tube, thereby providing frictional resistance between the pull wire portion and the sidewall of the distal tube;
wherein the loop wire and the pull wire are positioned to secure the implantable medical device to the detachment system, and
wherein the frictional resistance provided by the pull wire portion against the tubular body is effective to inhibit premature detachment of the implantable medical device as the implantable medical device is delivered by the detachment system to the target location of the body vessel.
