Abstract
A method and system for positioning a detachment zone and an implant, such as a vaso-occlusive coil or a stent, attached thereto in a body. A catheter is inserted within a vascular cavity in the body. The implant is attached to a distal end of a delivery member using a temporary connection, such as an electrolytic, mechanical, hydraulic, heat-sensitive or Radio Frequency (RF) sensitive connection, with an insulation member between the wire and the implant. The delivery member, temporary connection and implant are advanced through the catheter. An electrical condition, such as current, voltage and impedance, related to the position of the temporary connection in the catheter is monitored with an electrical measurement device or sensor. The electrical condition changes when the temporary connection reaches or exits a predetermined location, for example, the distal end of the catheter and contacts a conductive component of the body, such as blood in an aneurysm.
