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.
L'invention concerne un dispositif permettant d'assurer l'occlusion d'un espace dans le corps, utile en particulier comme dispositif pour l'occlusion vasculaire. Spécifiquement, le dispositif comprend en général une âme métallique ou un noyau, et deux pièces conjointes en matériau polymère (souvent des éléments polymères) n'ayant pas la même capacité de thrombogenèse. Généralement, le noyau comprend une bobine métallique à enroulement hélicoïdal; les premiers et seconds éléments polymères sont des matériaux fibreux tissés sous forme de structure tressée. Le type de dispositif considéré peut être placé à l'endroit voulu, dans le corps d'un mammifère, pour faciliter la formation d'une occlusion. Le dispositif en question contribue à la formation de tissu cicatriciel, de tissu d'un site en voie de cicatrisation, ou de néocapillaires dans les occlusions établies via le dispositif lui-même.
