A medical device for placing an embolic device (23) at a predetermined site within a vessel of the body including a delivery catheter (12) and a flexible pusher member (16) having a lumen therethrough and being slidably disposed within the lumen of the catheter (12). A stretch resistant embolic device (23) is retained within the delivery catheter (12) by a mechanical interlocking mechanism which includes an engagement member (18) which is slidably disposed within the pusher member (16) and extends through a retaining ring (28) at the proximal end of the embolic device (23). A detachment member (30) extends through an aperture (22) at the distal end of the engagement member (18) thereby locking the embolic device (23) onto the engagement member (18). When the embolic device (23) is advanced to the predetermined site within the vessel, the detachment member (30) is withdrawn from the aperture (22) to thereby release the embolic device (23) at the treatment site. |
