Title (EN) VASCULAR CAST-BASED SCAFFOLDS AND METHODS OF MAKING THE SAME
(FR) ÉCHAFAUDAGES VASCULAIRES À BASE DE COULÉE ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) The present application relates to biomimetic three-dimensional (3D) scaffolds, constructs and methods of making the same. The three-dimensional scaffold can include a sacrificial internal cast and a durable external scaffold material, wherein the durable external scaffold material comprises a biocompatible material which completely surrounds the sacrificial internal cast and wherein the sacrificial internal cast be removed to yield a branching 3D network of hollow, vessel-like tubes that substantially mimics a native tissue or organ.
(FR) La présente invention concerne des échafaudages tridimensionnels (3D) biomimétiques, des constructions et des procédés de fabrication de ceux-ci. L’échafaudage tridimensionnel peut comprendre un moulage interne sacrificiel et un matériau d’échafaudage externe durable, le matériau d’échafaudage externe durable comprenant un matériau biocompatible qui entoure complètement le moulage interne sacrificiel et le moulage interne sacrificiel étant enlevé pour obtenir un réseau ramifié 3D de tubes creux, de type vaisseau qui imite sensiblement un tissu ou organe natif.
