Abstract
Abstract This is a device for occluding a space within the body, and particularly, it is useful as a vaso-occlusive device. In particular, it typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member will comprise a metallic helically-wound coil; the first polymeric member and second polymeric member will be fibrous materials woven into a braid. These devices may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The inventive device has been found to promote the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
91 words
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 first fibrous member attached to the elongated core member, and a second fibrous member attached to the elongated core member, the elongated core member having a proximal end and a distal end, the first fibrous member comprised of a first polymeric material, the second fibrous member comprised of a second polymeric material different from the first polymeric material.
Claim 2
Dependent Claim
91 words
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 first fibrous member attached to the elongated core member, and a second fibrous member attached to the elongated core member, the elongated core member having a proximal end and a distal end, the first fibrous member comprised of a first polymeric material, the second fibrous member comprised of a second polymeric material different from the first polymeric material.
Claim 3
Dependent Claim
