First Claim
Patent Images
1. A mammalian implant assembly comprising:
- a wire having an axis, a proximal end, and a distal end, a distal portion of the wire comprising a discrete metallic link that is susceptible to electrolytic disintegration in an ionic medium, a section of the wire proximal of said link being insulated so as to not be susceptible to electrolytic disintegration in the ionic medium; and
a detachable implant coupled to the wire by a solder-less attachment at a location that is distal to the discrete metallic link, the implant comprised of a material not susceptible to electrolytic disintegration in an ionic medium.

Abstract
A solderless sacrificial link between a detachable member which is placed at and is intended to remain at a desired site within the mammalian body and the core wire used to introduce the detachable member. The detachable member device may be one used to create emboli in the vascular system or may be of any other type deliverable into the human body and detached into an ionic aqueous environment, either for later removal or permanent placement.
