Vaso-occlusive member assembly with multiple detaching points
First Claim
1. An assembly for use in the formation of an occlusion comprising:
- an occlusive member having a proximal end, an insulative joint located proximally on said occlusive member, an electrolytically disintegratible link located proximally of said insulative joint, and a conductive joint located proximally on said electrolytically disintegratible link, said joint configured for connection to an additional occlusive member.

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.

15. A method for occluding a body cavity, comprising:
-
disposing an assembly at least partially into said body cavity, said assembly comprising (i) a wire having a first insulative joint attached to a distal end of said wire, a first vaso-occlusive member attached to said first insulative joint, and (ii) at least one section comprising (1) a conductive joint attached to said first vaso-occlusive member, (2) an electrolytically disintegratible link having a proximal end attached to said conductive joint and a distal end attached to an additional insulative joint, and (3) an additional vaso-occlusive member attached to said additional insulative joint, and electrolytically disintegrating said link to leave at least a portion of said assembly within said body cavity. - View Dependent Claims (16, 17, 18, 19, 20)
