    摘要: Methods of compressing a stented prosthetic heart valve are disclosed. The method including inserting a stented prosthetic heart valve having a self-expandable stent frame into a container, initiating a cooling element in the container, transferring heat through a thermal conductor to cool an interior of the container, reducing a temperature of the self-expandable stent frame while located within the container to a critical temperature of not greater than 8° C., and compressing an outer diameter of the stented prosthetic heart valve while the stented prosthetic heart valve is at the critical temperature.

    摘要: A transcatheter valve prosthesis including a sealing component formed from a tissue having an altered extracellular matrix. The altered extracellular matrix includes at least one weakened connection such that the tissue is configured to swell or expand upon contact with a fluid. The altered extracellular matrix does not reduce compressibility of the tissue such that the delivery profile of the transcatheter valve prosthesis is not adversely affected. The tissue having an altered extracellular matrix transforms from a compressed state for delivery within a vasculature to an expanded state in situ when blood infiltrates or flows within the at least one weakened connection. The sealing component in the expanded state conforms to the geometry of the native valve tissue, thereby preventing paravalvular leakage at the implantation site.
