Title
(EN) A COMPOSITE MULTI-LAYERED VASCULAR GRAFT PROSTHESIS
(FR) GREFFE COMPOSITE
Abstract
(EN)
Composite vascular grafts, their methods of construction, and methods of use are disclosed. In some embodiments, the grafts are tubular multilayer composite grafts having a luminal blood-contacting elastin layer and an outer collagen layer to impart mechanical strength to the elastin layer. The elastin and collagen layers may comprise substantially acelluar matrixes isolated from the tissue of an animal. In particular embodiments the blood contacting layer consists essentially of pure elastin, and is substantially free of collagen. An adhesive may be used to secure the collagen and elastin layers to one another. Growth factors may be added to the adhesive of the elastin or collagen layers to promote in growth of cells into the graft.

L'invention concerne des greffes vasculaires composites, leur procédé de construction et leur méthode d'utilisation. Dans certains modes de réalisation, les greffes sont des greffes composites tubulaires multicouches comprenant une couche d'élastine en contact avec le sang et une couche extérieure de collagène destinée à conférer une résistance mécanique à la couche d'élastine. Les couches d'élastine et de collagène peuvent comprendre des matrices acellulaires isolées du tissu d'un animal. Dans des modes de réalisation particuliers, la couche en contact avec le sang est essentiellement composée d'élastine pure, et est sensiblement exempte de collagène. On peut utiliser un adhésif pour fixer les couches de collagène et d'élastine l'une à l'autre. On peut également ajouter des facteurs de croissance à l'adhésif des couches de collagène et d'élastine afin de promouvoir la croissance des cellules de la greffe.
