Abstract

Flexible polymeric layered structures are disclosed. A first polymer layer (e.g. biocompatible polyurethane) is moulded over a support (e.g. a frame or another polymer layer) by drying from solution. A porous layer of polymer fibres (e.g. biocompatible polyurethane) is applied over the first polymer layer. A protective barrier layer (e.g. gold) is applied over the porous layer. A further polymer layer is applied over the porous layer, allowing attachment of the further polymer layer to the porous layer by keying. The polymer layers may be reinforced by fibres, e.g. carbon nanotubes. The layered structures are of particular use for heart valve leaflets.
