Vaso-occlusive member assembly with multiple detaching points

An assembly for use in the formation of a vascular occlusion comprising:

• a proximal section comprising a core wire having a proximal end and a distal end, a first electrically insulative joint attached to the distal end of said core wire, and a first vaso-occlusive member attached to said first electrically insulative joint,
• one or more distal sections, each comprising an electrically conductive joint attached to a distal electrolytically disintegratible link, an additional electrically insulative joint located distally on said electrically disintegratible link, and an additional distal vaso-occlusive member, and
• a catheter having a proximal end and a distal end and having an electrode configured for electrical contact with one of said vaso-occlusive members,
• whereby upon application of electrical current to a distal section, one of said electrolytically disintegratible links disintegrates, releasing a portion of said assembly.
