Soft-ended fibered micro vaso-occlusive devices

摘要

This is a micro-vaso-occlusive device intended generally for occlusion of small arteries located distally in the vasculature. The device is made up of a binder, often radio-opaque, which may be short in length by comparison to the length of the included thrombogenic fibers. The fibers form the other portion of the device. At least one end of the device includes a solid but comparatively soft end typically made of a molten mass of the fibers. The micro device may have multiple binder sections. The fibers may be straight, looped, or tufted.
