Abstract

This is an implant for placement in the human body and a wire coupled to the implant for placing that implant. In the illustrated embodiment, it is an implant for use in the vasculature of the human body and is used to occlude a cavity in that vasculature as a portion of a treatment regimen. The implant itself is a component of a deployment device in which the implant is detached from the wire using electrolytic disintegration when a current is applied to the wire. The implant is electrically isolated from active participation in the electrolytic disintegration which occurs when a current is applied to the wire. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of a selected portion of the wire to electrolysis to provide for quick erosion and detachment of the implant from the wire. Although the implant itself is preferably a vaso-occlusive device, it may instead be used for any implant which may be installed in this manner.
