Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a delivery apparatus can include a first shaft configured to rotate around a central longitudinal axis of the delivery apparatus to rotationally align a prosthetic valve mounted on the delivery apparatus with native anatomy, a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end portion of the first shaft, an inflatable balloon coupled to the distal end portion of the first shaft, and a distal shoulder mounted on the distal end portion of the second shaft and arranged within a distal end portion of the balloon. The distal shoulder comprises a base portion and a flared portion that extends radially outward from the base portion, and a radiopaque marker is disposed on the flared portion.

Methods and systems for aligning a commissure of a prosthetic heart valve with a commissure of a native valve

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.
