A stent-graft composite intraluminal prosthetic device comprises an elongated radially adjustable tubular stent and a polyolefin stent cover positioned about an exterior surface and/or interior surface thereof. The composite device is formed heat melting a film-like layer of polyolefin material onto a stent placed on a mandrel. The film has opposed longitudinal edges which are joined to form a tubular structure. The stent has a plurality of open spaces extending between opposed interior and exterior surfaces to permit radial adjustability, and the stent and cover are secured together through the open spaces of the stent. When both an exterior stent surface an interior stent surface are to be covered, such layers may be adheringly secured through the spaces by an adhesive, or laminated together through the open spaces of the stent.

La présente invention concerne un dispositif prothétique intraluminal composite de stent à greffer qui comprend un stent tubulaire effilé réglable radialement et une enveloppe de stent en polyoléfine placée autour d'une surface extérieure et/ou intérieure de ce stent. On fabrique ce dispositif composite en faisant fondre à la chaleur une couche de type film d'un matériau en polyoléfine sur un stent placé sur un mandrin. Ce film présente des bords opposés qui sont joints de façon à former une structure tubulaire. Ce stent possède une pluralité d'espaces ouverts situés entre les surfaces intérieures et extérieures opposées afin de permettre un réglage radial, et ce stent et son enveloppe sont fixés ensemble par ces espaces ouverts du stent. Lorsqu'une surface extérieure et une surface intérieure du stent doivent être recouvertes, ces couches peuvent être fixées de façon adhérante à travers les espaces par un adhésif, ou laminées ensemble à travers les espaces ouverts de ce stent.
