Endovascular electrolytically detachable guidewire tip for the electroformation of thrombus in arteries, veins, aneurysms, vascular malformations and arteriovenous fistulas

A guidewire for use in formation of an occlusion within a vascular cavity used in combination with a microcatheter comprising:

• a core wire, said core wire having a distal portion susceptible to electrolytic distintegration in blood;
• and
• an elongate tip portion extending said core wire for a predetermined lineal extent adapted to form said occlusion in said vascular cavity and coupled to said distal portion of said core wire tip portion for endovascular insertion within a vascular cavity, said elongate tip portion not being susceptible to electrolytic disintegration in blood,
• whereby endovascular occlusion of said vascular cavity can be performed.

• wherein said elongate tip portion is a long and substantially pliable segment and is comprised of a mental not susceptible to electrolytic disintegration within blood, and
• wherein said long and pliable segment is prebiased to form a helix when extended from said microcatheter,
• whereby endovascular occlusion of said vascular cavity can be performed.
