Abstract:
A system for use in the formation of an occlusion in a mammalian body comprising:a.) a sacrificial link system made up of:i. a core wire having a proximal end and a distal end, said core wire with an axis having a distal, discrete, sacrificial link susceptible to electrolytic disintegration in blood, said core wire not being susceptible to electrolytic disintegration proximally of said link, andii. an 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 blood and joined to said core wire without solder,b.) a power supply for providing electrical current to the core wire, andc.) a catheter sheath for surrounding the core wire and elongate tip portion during introduction to the selected site.
