    摘要: A method of implanting a prosthetic heart valve includes selecting a prosthetic heart valve. The selected prosthetic heart valve has a nominal diameter that is greater than a native annulus diameter of a native annulus by up to forty percent. The method further comprises compressing the selected prosthetic heart valve to a radially compressed configuration in which the selected prosthetic heart valve has a first diameter that is less than the nominal diameter, positioning the selected prosthetic heart valve within the native annulus, and expanding the selected prosthetic heart valve from the radially compressed configuration to a radially expanded configuration in which the selected prosthetic heart valve has a second diameter which is less than the nominal diameter by up to ten percent and which is greater than the first diameter.

    摘要: A delivery apparatus comprises a handle, a first shaft, and a second shaft. The first shaft extends through and is movable axially relative to the second shaft. The delivery apparatus comprises an inflatable balloon having a proximal end portion coupled to the second shaft and a distal end portion of the balloon coupled to the first shaft. An inflation hub assembly comprises an inflation manifold and a piston, wherein the inflation manifold comprises a main body defining a main lumen and an inflation port defining an inflation port lumen. The piston extends into the main lumen and is slidable relative to the inflation manifold. A proximal end portion of the first shaft is coupled to the piston. The piston is moveable relative to the inflation manifold in proximal and distal directions to produce movement of the first shaft and adjust the length of the balloon.
