  • Patent number: 11865226
    Abstract: Cardiovascular prostheses for treating, reconstructing and replacing damaged or diseased cardiovascular tissue that include particulate structures that are formed from PGS, cerivastatin and everolimus. The particulate structures are configured to modulate inflammation of damaged cardiovascular tissue in vivo by increasing expression of Kruppel like factor 2 (KLF-2), whereby localized expression of monocyte chemoattractant protein 1 (MCP-1) and C-C chemokine receptor type 2 (CCR2) is inhibited at transcriptional and translational levels as a function of the KLF-2 modulation.

  • Patent number: 10993802
    Abstract: A biocompatible and biodegradable construct having a base expandable member and an integral, internal support structure. The support structure is preferably formed from poly(glycerol sebacate) (PGS) or a magnesium alloy. The base member is preferably formed from acellular extracellular matrix (ECM) derived from small intestine submucosa (SIS) tissue that exhibits a flexible, porous, sponge-like structure adapted to expand upon absorption of a bodily fluid, wherein the construct seals a perivalvular leak when disposed proximate thereto.

  • Patent number: 10857263
    Abstract: A percutaneous transseptal surgical implantation method for replacing a defective atrioventricular (AV) valve with a conical shaped prosthetic valve formed from extracellular matrix (ECM) tissue. When the method is employed to replace a native mitral valve, the method positions the prosthetic tissue valve in the mitral valve region, whereby the valve does not obstruct the outflow tract of the aortic valve and prevents the leaflets of the aortic valve from coapting.

  • Patent number: 10512711
    Abstract: The invention is to articles made from extracellular matrix sheets that encase biodegradable polymeric material. Methods of healing wounds or regenerating tissue at sites of defect by placing said articles in mammals are claimed. The biodegradable polymer can change quality upon contact with a physiological parameter such as temperature or pH that causes, for example, a liquid polymer to gel or harden. The degradation of the polymer can be controlled to suit a tissue regeneration or wound healing time course. Additional components such as proteins, cells and drugs can be added to the biopolymer composition.
