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 “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

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.
摘要翻译： 一种经导管瓣膜假体，其包括由具有改变的细胞外基质的组织形成的密封组件。 改变的细胞外基质包括至少一个弱化的连接，使得组织构造成在与流体接触时膨胀或膨胀。 改变的细胞外基质不会降低组织的压缩性，使得经导管瓣膜假体的输送分布不受不利影响。 具有改变的细胞外基质的组织当血液渗入或流入至少一个弱化的连接内时，从压缩状态转换成脉管系统内的扩张状态。 处于膨胀状态的密封部件符合天然瓣膜组织的几何形状，从而防止植入部位的瓣膜溢出。
