An embolization delivery system and a method of using the system by a physician to deliver an embolization coil into the vasculature of a patient is disclosed. The embolization delivery system includes a delivery tube in the form of a catheter or wire guide that may be reversibly inserted, a delivery catheter placed into the vasculature of a patient, a connector disposed around and permanently coupled to the delivery tube, a detachable embolization coil disposed within a portion of the connector and held in place by compressive forces exerted by the connector, and a release mechanism for detaching the embolization coil. The release mechanism includes a wire with one end being coupled to the catheter, a middle portion being in contact with both the connector and coil, and a second end that may be manipulated in a predetermined manner by the attending physician. The manipulation of the wire splits part of the connector, thereby reducing the compressive forces exerted by the connector onto the embolization coil and allowing the coil to detach from the embolization delivery system.
