Abstract
A medical device for placing an embolic device, such as an embolic coil at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. An embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes a deflectable engagement member attached to the distal end of the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the pusher member. When the detachment member is withdrawn from the aperture of the engagement member the engagement member deflects to release the embolic device.
