CA 2464661

A tissue graft product includes at least one collagen layer comprised of submucosa or renal capsule tissue having slits therein to provide a mesh pattern which in turn establishes a graft structure that is highly deformable. The slits and mesh pattern provide for improved characteristics when utilized as a tissue graft and in particular an external wound care. Preferred devices have multiple submucosa, renal capsule or other collagenous extracellular matrix layers, providing a substantial and lasting scaffold for tissue ingrowth during wound treatment.

L'invention concerne un produit formant greffon de tissu. Ce produit comprend au moins une couche de collagène constituée de tissu de sous-muqueuse ou de capsule rénale qui comporte des fentes pour former un motif maillé qui, à son tour, constitue une structure de greffon très déformable. Les fentes et le motif maillé assurent des caractéristiques améliorées lors de leur utilisation comme greffon de tissu, et en particulier, comme soins pour blessures externes. Les dispositifs préférés présentent de multiples couches de matrice extracellulaire de collagène , de capsule rénale ou de sous-muqueuse ou d'autres couches de matrice extracellulaire de collagène . On obtient ainsi une base durable et importante pour l'interposition du tissu pendant le traitement des blessures.
