Tissue prostheses for repairing, reconstructing and replacing damaged or diseased biological structures and associated tissue
View Patent ↗Non-antigenic, resilient, bioremodelable, biocompatible tissue prostheses that can be engineered into a variety of shapes and used to repair, augment, reconstruct or replace damaged or diseased biological structures and associated tissue.
1. A tissue prosthesis for reconstructing and replacing damaged biological structures and tissue, comprising:
a seamless tubular member comprising a decellularized mammalian tubular structure, said tubular structure having a first length, proximal and distal ends, an outer surface and a lumen that extends therethrough,
said tubular structure further comprising at least one coating, said coating comprising poly(glycerol sebacate) (PGS), said PGS coating being disposed on at least a portion of said tubular structure outer surface,
said coated tubular structure being configured to induce modulated healing when said tubular member is disposed proximate damaged biological tissue, said modulated healing comprising modulation of inflammation of said damaged tissue, host tissue proliferation, bioremodeling of said damaged tissue, and regeneration of new tissue and tissue structures with site-specific structural and functional properties.
2. The tissue prosthesis of claim 1 , wherein said mammalian tubular structure comprises a segment of a mammalian structure selected from the group consisting of mammalian intestine, umbilical artery and vein, ureter, mesenteric vessel and jugular vein.
3. The tissue prosthesis of claim 1 , wherein said mammalian tubular structure comprises a segment of adolescent small intestine.
4. The tissue prosthesis of claim 1 , wherein said tubular structure further comprises at least a first exogenously added biologically active agent.
5. The tissue prosthesis of claim 4 , wherein said first biologically active agent comprises a growth factor selected from the group consisting of transforming growth factor-beta (TGF-β), and basic fibroblast growth factor (bFGF).
6. The tissue prosthesis of claim 5 , wherein said tubular structure further comprises a statin selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin and simvastatin.
7. The tissue prosthesis of claim 1 , wherein said coating comprises an extracellular matrix (ECM) composition comprising an ECM material selected from the group consisting of small intestine submucosa (SIS), urinary bladder submucosa (UBS), stomach submucosa (SS), liver basement membrane (LBM), intact basement membrane, placental extracellular matrix, omentum extracellular matrix, cardiac extracellular matrix, kidney extracellular matrix, pancreas extracellular matrix, lung extracellular matrix, and combinations thereof.
8. The tissue prosthesis of claim 1 , wherein said tubular structure further comprises reinforcement means.
9. The tissue prosthesis of claim 1 , wherein said tubular structure further comprises at least one anchoring mechanism.
