Title
(EN) IN VIVO NON-DEGRADABLE ANTI-ADHESIVE MATERIAL
(FR) MATÉRIAU ANTI-ADHÉSIF NON DÉGRADABLE IN VIVO
(JA) 生体内非分解性癒着阻止材
Abstract
(EN)
The purpose of the present invention is to prevent bonding, that is, adhesion which occurs between a wound area and surrounding tissues thereof, or between two organs that are originally separated from each other. The anti-adhesive material of the present invention is characterized by having at least a portion thereof made of an in vivo non-degradable material, wherein the contact angle of water to the surface of the anti-adhesive material is at most 7°, or at least 90°.
(FR)
Le but de la présente invention est d'empêcher la liaison, c'est-à-dire l'adhérence qui se produit entre une zone de plaie et des tissus environnants de celle-ci, ou entre deux organes qui sont à l'origine séparés l'un de l'autre. Le matériau anti-adhésif de la présente invention est caractérisé en ce qu'au moins une partie de celui-ci est constituée d'un matériau non dégradable in vivo, l'angle de contact de l'eau sur la surface du matériau anti-adhésif étant d'au plus 7°, ou d'au moins 90°.
(JA)
創傷部とその周囲組織との間、或いは本来は分離している臓器間に生じる結合すなわち癒着を阻止すること。本発明の癒着阻止材は、少なくとも一部が生体内非分解性材からなり、表面の水に対する接触角が7度以下、又は90度以上である事を特徴とする。
