Abstract

A vaso-occlusive device delivery assembly includes a pusher assembly having a proximal end, a distal end, and a pusher lumen extending therebetween; a vaso-occlusive device; and a tubular member mechanically connecting the pusher assembly to the vaso-occlusive device, the tubular member having a proximal end, a distal end, a tube lumen extending therebetween, and a detach zone, wherein the proximal end of the tubular member extends into the pusher assembly lumen at the distal end of the pusher assembly. A heat generating member is disposed in the tube lumen, such that, when activated, the heat generating member generates heat that melts or otherwise thermally degrades the tubular member at the detach zone, thereby detaching the vaso-occlusive device from the pusher assembly.
