    摘要： Disclosed are a braided tube forming device used for assisting in manufacturing of braided tubes, and a use method. In at least one embodiment, the device provides at least one elongated mandrel, and at least one elongated radially contractive primary tube; and the size and structure of the primary tube are set such that the at least one elongated mandrel is removably received in the primary tube. Each of the at least one primary tube provides a plurality of spaced primary tube parts that are arranged circumferentially and configured to cooperate to define the primary tube. During use, after the braided tube is circumferentially formed on the outer surface of the at least one primary, the at least one mandrel is removed form the at least one primary tube, thereby allowing the primary tube parts to move radially in ward toward each, such that the braided tube can be disengaged from the at least one primary tube.

    摘要： A prosthetic mitral valve assembly and method of inserting the same is disclosed. In certain disclosed embodiments, the prosthetic mitral valve assembly includes a stent and valve combination. The stent is designed so that the anchoring portion is positioned above the annulus of the mitral valve and in the left atrium. The stent is radially expandable so that it can expand into position against the walls of the left atrium and accommodate a wide range of anatomies. Contact between the stent and the native tissue in the left atrium reduces paravalvular leakage and prevents migration of the stent once in place.
