Forbedret elektrolyttisk adskillbar skjöt for endovasculære emboliske innretninger

摘要

This invention is an apparatus for endovascular occlusion through the formation of thrombi in arteries, veins, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, it deals with an improved sacrificial link (141) between an endovascular device (104) which is introduced to and is intended to remain at the desired thrombus formation site and the device (137) used to introduce the device (104). The discrete sacrificial link (141) is a groove produced by laser scoring through a polymer coating. The invention further includes a method for introduction of the device and its electrolytic separation.
