Abstract
A device for occluding a space within the body, and particularly,the device usefle as a vaso-occlusive device. In partiular, the device typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member comprises a metallic helically-wound coil; the first polymeric member and second polymeric member are fibrous materials woven into a braid. The device may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The device promotes the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.
Claims16
A vaso-occlusive implant with a size, shape, and configuration of such that it may be introduced and implanted into a mammalian blood vessel, the implant comprising in combination an elongated core member, a fibrous member attached to the elongated core member, the elongated core member having a proximal end and a distal end, the fibrous member comprised of a copolymer comprising a first polymeric material, and a second polymeric material different from the first polymeric material.
A vaso-occlusive device comprising a core member with a size, shape, and configuration of such that it may be introduced and implanted into a mammalian blood vessel, comprising a core member and a biodegradable fibrous material of a type promoting production of neo-capillaries in said blood vessel.
