POWER SUPPLY USING TIME VARYING SIGNAL FOR ELECTROLYTICALLY DETACHING IMPLANTABLE DEVICE

摘要

A medical system comprises an implant assembly including an elongated pusher member, an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member, and an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, the medical system comprising an electrical power supply coupled to the implant assembly, and configured for conveying a time varying signal having net positive electrical energy to the severable joint to detach the implantable device from the pusher member.
