First Claim
Patent Images
1. A sacrificial link assembly having a single electrolytically severable region for use in the formation of an occlusion comprising:
- a core wire having a proximal end and a distal end and an axis between the proximal end and distal end, said core wire having a distal, single, electrolytically severable region wherein said region is a discrete, metallic sacrificial link susceptible to electrolytic disintegration in an ionic medium and having no solder in the vicinity of said sacrificial link, said core wire not being susceptible to electrolytic disintegration proximally of said link, andan elongate tip portion joined to and extending beyond said core wire and adapted to form said occlusion in a selected site within a mammal vasculature and coupled to the distal end of the core wire for endovascular insertion to the selected site, said elongate tip portion not being susceptible to electrolytic disintegration in an ionic medium.

Abstract
This is 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.
