Claim:
1. A vaso-occlusive device delivery assembly, comprising: 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, proximal and distal seals attached to, and forming respective seal with, the respective proximal and distal ends of the tubular member, such that the tubular member, proximal seal, and distal seal, collectively form a substantially fluid-tight chamber within the tube lumen, wherein the proximal end of the tubular member extends into the pusher assembly lumen at the distal end of the pusher assembly, and wherein 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.
