| Embolization materials are medical devices that are used to intentionally impede blood flow to a region of the body to relieve hemorrhage, block blood vessels feeding specific sites such as tumors and fibroid or to stabilize an aneurysm. In addition to metallic coils, a wide variety of polymer based particulate and fluid based materials have been used for this purpose including biodegradable starches and collagen as well as synthetic polymers including polyvinyl alcohol copolymers, acrylic hydrogels, cyanoacrylates and poly(ethylene vinyl alcohol) copolymers. For embolization of larger vessels the use of polymeric balloons has also been employed. Typically, these embolic agents are introduced through minimally invasive percutaneous procedures performed using imaging technologies such as fluoroscopy. This presentation will overview the evolution and diversity of commercially available polymer based medical devices used in the clinic for embolization procedures. |
