This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

Prosthetic heart valves having a conical shaped base valve structure formed from collagenous mammalian tissue. The base valve structure includes a plurality of elongated ribbon members that are positioned proximate each other in a joined relationship, wherein the elongated ribbon members are positioned adjacent each other and form a plurality of fluid flow modulating regions that open when fluid into and through the base valve structure exhibits a positive pressure relative to the exterior pressure, i.e., a positive pressure differential, wherein the fluid is allowed to be transmitted out of the base valve structure, and transition to a closed configuration when the pressure differential between the interior valve pressure and exterior pressure reduces, wherein the fluid is restricted from flowing out of the base valve structure.

A collagen-coated tissue based membrane that is smooth on both sides so as to inhibit cell and tissue adhesion. Also disclosed are methods for making a collagen-coated tissue-based membrane.

A matrix, including epithelial basement membrane, for inducing repair of mammalian tissue defects and in vitro cell propagation derived from epithelial tissues of a warm-blooded vertebrate.

The present invention relates to an injection formulation composition for use as a filler or a drug carrier through a click chemistry reaction. More specifically, the present invention relates to an injection formulation composition comprising: a first liquid comprising a first biopolymer having a first click chemistry functional group introduced thereinto; and a second liquid comprising a second biopolymer having a second click chemistry functional group introduced thereinto, wherein the first click chemistry functional group is chemically linkable with the second click chemistry functional group, to a method for preparing an injection formulation hydrogel using the composition, and to a medical filler, an in-vivo injection type supporter, or a drug carrier using the composition.

A CO.sub.2 processed sheet structure comprising ECM derived from mammalian submucosa tissue, which can be formed into a pouch configured to encase a medical device.

A collagen-coated tissue-based membrane that is smooth on both sides so as to inhibit cell and tissue adhesion. The tissue-based membrane is a serous membrane having a fibrous surface and a smooth surface and the collagen is coated on the fibrous surface. Also provided are methods for making the collagen-coated tissue-based membrane.

Vascular grafts for treating, reconstructing and replacing damaged or diseased cardiovascular vessels that are formed from decellularized extracellular matrix (ECM). The vascular grafts include structural reinforcement means, such as a strand of wound biodegradable polymeric material disposed proximate the outer surface of the graft.

Described are packaged, sterile medical graft products containing controlled levels of a growth factor such as Fibroblast Growth Factor-2 (FGF-2). Also described are methods of manufacturing medical graft products wherein processing, including sterilization, is controlled and monitored to provide medical graft products having modulated, known levels of a extracellular matrix factor, such as a growth factor, e.g. FGF-2. Preferred graft materials are extracellular matrix materials isolated from human or animal donors, particularly submucosa-containing extracellular matrix materials. Further described are ECM compositions that are or are useful for preparing gels, and related methods for preparation and use.

Provided herein is a method for producing decellularized colonic extracellular matrix material. A decellularized colonic extracellular matrix material also is provided, along with uses for the material. Methods of use of the decellularized colonic extracellular matrix material also are provided, including methods of treating a defective, diseased, or damaged tissue or organ in a patient, and/or methods of treating esophageal disease, short bowel syndrome, ulcerative colitis, Crohn's disease, or mucositis in a patient.
