摘要： Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and/or one or more retaining portions. The valve seat can include radiopaque markers affixed to a frame or an impermeable member. The radiopaque markers can indicate a deployment location of the valve. The docking stations can be deployed from a catheter including one or more radiopaque markers. Relative positioning of two or more radiopaque markers can provide an indication of the amount of deployment of the docking station.

摘要： Docking stations are configured to retain and position a transcatheter heart valve in a circulatory system. The docking stations can comprise an expandable frame. The docking stations can include an enlarged first end portion having a first outer radial portion with a first major lateral dimension, an enlarged second end portion having a second outer radial portion with a second major lateral dimension, and a narrowed central waist portion having an inner radial portion with a third major lateral dimension smaller than the first and second major lateral dimensions. A retaining portion is at least partially defined by at least one of the first and second end portions, and a valve seat is at least partially defined by the waist portion. The docking station can be configured to adapt a native tricuspid valve to accept a smaller transcatheter heart valve.

摘要： A docking station for a prosthetic implant includes a frame. The frame includes one or more tissue engaging elements, which is some examples are apices of the frame formed by struts of the frame. The frame and/or the apices can be configured to engage native tissue at an implantation location to retain the position of the frame without damaging the native tissue. A docking station can also include a sealing skirt and/or a protective cover coupled to the frame. The sealing skirt can reduce retrograde blood flow through and/or around the frame. The protective cover can reduce damage to the native tissue.
