Abstract

This device is an apparatus for endovascular occlusion through the formation of thrombi in arteries, veins, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, the device includes multiple vaso-occlusive members connected by electrolytically disintegratible links. Each link connects to the vaso-occlusive member by electrically insulative and conductive joints on opposite ends of the link. The vaso-occlusive members are delivered through a delivery catheter having on its distal end an electrode for electrical contact with the vaso-occlusive member. Upon application of an electrical current through the electrode to the vaso-occlusive member and its conductive joint to the electrolytically disintegratible link, the link disintegrates, selectively detaching the desired number of vaso-occlusive members into the target thrombus formation site.

Claims

1. An occlusion assembly comprising:

a plurality of hollow, tubular coil segments; and

at least one connector member connecting adjacent coil segments, the connector member being detachable from selected portions of the coil segments by application of non-mechanical energy to the connector member.

2. The occlusion assembly of claim 1, further comprising a plurality of connector members.
