Abstract: An anti-fouling implantable material and a method of making the anti-fouling implantable material are disclosed. The anti-fouling implantable material includes a polymeric reinforcement layer, an intermediate layer comprising a protective polymer membrane, and an outer layer comprising an ionic polymer. The anti-fouling implantable material may have chemical and/or physical properties compatible with body tissue properties. The anti-fouling implantable material may be used for implantable medical devices, such as prosthetic heart valves and vascular grafts, among others.

Abstract: A sealing member for an implantable prosthesis includes a substrate comprising a substrate material, and one or more hydrogel structures disposed on an outwardly facing surface of the substrate. The hydrogel is stimulus responsive, and undergoes a change in volume, stiffness, or both when exposed to the stimulus. The sealing member promotes endothelialization and/or reduces paravalvular leakage.
