    Abstract: Devices and methods for crimping a prosthetic heart valve onto a delivery device are described. In some embodiments, valves are crimped over an inflatable balloon and between proximal and distal shoulders mounted on a shaft inside the balloon. Crimping methods can include multiple compression steps with the valve located in different axial positions relative to the crimping jaws at each different step. In some methods, the valve may extend partially outside of the crimping jaws during certain crimping steps, such that the crimping force is only applied to the part of the valve that is inside the jaws. Exemplary crimping devices can include two or more adjacent sets of jaws that close down to different inner diameters, such that different parts of a valve get compressed to different outer diameters at the same time during a single crimping step.

    Abstract: 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.
