Abstract
A vaso-occlusive device delivery assembly includes a pusher assembly having proximal and distal ends, a conductive sacrificial link disposed at the distal end of the pusher assembly, and a vaso-occlusive device secured to the pusher assembly by the sacrificial link. The pusher assembly includes first and second conductors extending between the proximal and distal ends thereof. The sacrificial link is electrically coupled between the first and second conductors, such that the first conductor, sacrificial link and second conductor form an electrical circuit, and, when a disintegration current is applied through the sacrificial link through the first and second conductors, the sacrificial link thermally disintegrates, thereby releasing the attachment member and vaso-occlusive device from the pusher assembly.
