Abstract: Cardiovascular prostheses for treating, reconstructing and replacing damaged or diseased cardiovascular tissue that are formed from acellular extracellular matrix (ECM). The cardiovascular prostheses comprise various compositions, such as ECM based compositions, and structures, such as particulate structures, mesh constructs, encasement structures, coated structures and multi-sheet laminate structures.
Abstract: A prosthetic atrioventricular tissue valve comprising a continuous tubular member formed from a first biocompatible material, the tubular member having proximal and distal ends, and at least one valve leaflet formed therein, the distal end of the tubular member including cardiovascular structure engagement means for connecting the tubular member to a cardiovascular structure, the cardiovascular structure engagement means comprising a plurality of elongated members that extend distally from the distal end of the tubular member.
Abstract: An expandable support member comprising an ECM composition that is configured to engage an interior region of a prosthetic valve and capable of transitioning from a pre-deployment configuration, where the support member is capable of being positioned at an interior valve region of the valve when the valve is disposed at a cardiovascular valve structure, to a post-deployment configuration when the support member absorbs a first bodily fluid and expands, where an outer surface region of the valve is placed in intimate contact with host cardiovascular tissue of the cardiovascular structure at a first position and seals perivalvular leaks present at the first cardiovascular structure position.

Abstract: A bioremodelable encasement structure comprising a pouch formed from at least one sheet of bioremodelable material, the pouch including an internal region that is configured to receive a device therein, the bioremodelable material comprising mesothelial tissue.
Abstract: An expandable member that is configured to engage an interior region of a prosthetic valve and capable of transitioning from a pre-deployment configuration at a pre-deployment temperature, where the expandable member is capable of being positioned in the valve at an interior valve region when the valve is disposed in a cardiovascular structure, to a post-deployment configuration when the expandable member is subjected to cardiovascular tissue temperature, where an outer surface region of the valve proximate the interior valve region is placed in intimate contact with host cardiovascular tissue of the cardiovascular structure at a first position and seals perivalvular leaks present at the first cardiovascular structure position.
Abstract: A multi-sheet extracellular matrix (ECM) structure for tissue regeneration, the ECM structure having joined first and second ECM sheet members and an agent dispersal network disposed between the sheets, the dispersal network being configured to receive and transfer a bioactive agent through the network and, when the ECM structure is attached to tissue, administer the bioactive agent to the tissue.
Abstract: Methods of treating biological tissue with bioremodelable tissue prostheses having a vasculature that is infused with a biomaterial composition.
Abstract: Extracellular matrix (ECM) constructs having a biodegradable support scaffold and an anchoring mechanism, which includes a plurality of biodegradable microneedles that are capable of piercing tissue and anchoring therein. In a preferred embodiment, the support scaffold and anchoring mechanism comprise an ECM material. In some embodiments, the microneedles are also capable of administering a biologically active agent and/or a pharmacological composition to the engaged tissue.
Abstract: A bioremodelable encasement structure comprising a pouch formed from at least one sheet of bioremodelable material, the pouch including an internal region that is configured to receive a device therein, the bioremodelable material comprising mesothelial tissue.
Abstract: A pouch structure formed from extracellular matrix (ECM) derived from small intestine submucosa (SIS) that includes an internal region configured to receive a medical device therein. The pouch structure is configured to modulate inflammation of damaged biological tissue and induce cell and tissue proliferation, bioremodeling of the damaged biological tissue, and regeneration of tissue structures with site-specific structural and functional properties, when implanted in a subject.
