Bioabsorbable metallic alloy coils coated with a polyurethane for treating intracranial aneurysms (ias) and renal artery aneurysms (raas)

Abstract

The invention includes bioabsorbable metallic alloy coils coated with one or more of a biodegradable elastomer, polymer, polyurethane, and/or polyurethane urea, and methods for treating intracranial aneurysms and renal artery aneurysms. According to the invention, a coated, biodegradable vaso-occlusive device includes at least one endovascular coil composed of a magnesium alloy and a coating including at least one of a biodegradable elastomer, polymer, polyurethane, and polyurethane urea, applied to or deposited onto a surface of the magnesium alloy. The vaso-occlusive device is introduced into a patient's body, transported to a targeted site, and implanted at the targeted site to treat the patient having an abnormal blood flow at the targeted site.
