Abstract
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, 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 third shaft surrounding the first shaft. The first shaft is configured to rotate within the third shaft and translate axially relative to the third shaft, and the third shaft includes a distal tip portion including a plurality of internal helical expansion grooves and a plurality of external helical expansion grooves that are configured to allow the distal tip portion to flex radially outward.
