Abstract: The present invention relates to compositions comprising a decellularized tissue. The present invention also provides an engineered three dimensional lung tissue exhibiting characteristics of a natural lung tissue. The engineered tissue is useful for the study of lung developmental biology and pathology as well as drug discovery.

Abstract: Devices and methods for reinforcing a tissue-based heart valve are provided. A reinforced tissue valve can provide structure and rigidity to withstand stresses that occur within the vasculature. In some instances, thickened tissue provides structure or rigidity. In some instances, a biocompatible filler is utilized within folded, rolled, or layered tissue. In some instances, a mesh is included with a reinforced tissue valve for further strength. In some instances, a mesh frame is utilized along the sidewall of a tissue-based heart valve. In some instances, a leaflet assembly is provided within a conduit having thickened tissue at the leaflet commissures.

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: The present invention provides a tissue-engineering vascular graft (TEVG) comprising a biodegradable scaffold, and a plurality of stem cell-derived vascular smooth muscle cells (VSMCs), wherein the plurality of stem cell-derived VSMCs are seeded on the biodegradable synthetic polymer scaffold and are cultured under mechanical and biochemical stimulation.

Abstract: An annuloplasty ring prosthesis comprising a frame having an outer surface; and a cover surrounding the frame. The cover comprises a bioprosthetic tissue that can be regenerative or fixed and non-regenerative. The frame can be bioabsorbable or non-degradable. A ring prosthesis and a method of manufacturing a ring prosthesis is also provided. The ring prosthesis comprising an elongated rod member formed into a substantially ring shape, the elongated rod member being formed substantially from a flat bioprosthetic tissue.

Abstract: The present invention provides compositions and devices that release (a) a nitric oxide (NO) donor and/or NO, and (b) an agent that aggregates and/or trimerizes the Fas receptor, such as but not limited to a Fas-ligand (FasL). In certain embodiments, the invention includes a stent that elutes (a) a NO donor and/or NO, and (b) FasL. In other embodiments, the invention includes methods of treating a condition, such as intimal hyperplasia, in a subject by administering a stent that releases (a) a NO donor and/or NO, and (b) FasL.
