Abstract:
1. A bioresorbable device for facilitating healing and repair of tissue comprising, in combination and in vitro: a macrostructure made from a polymer providing an internal three-dimensional architecture defining a network of void spaces, said macrostructure comprising a plurality of zones, having at least a first zone and a second zone; a microstructure comprising at least one material for enhancing the attachment of cells to the three-dimensional architecture, said at least one material carried by the macrostructure within the void spaces of the three-dimensional architecture, said microstructure having the same architecture as said macrostructure but on a microscopic scale; a hydrophobic barrier being arranged between said first zone and said second zone, said hydrophobic barrier comprising a region of said macrostructure wherein surface properties of said macrostructure are altered without altering the geometry or mechanical characteristics of said macrostructure; and a plurality of cells attached to the three-dimensional architecture of the macrostructure of the device, wherein said plurality of cells are arranged to be transported to a repair site.
