Methods and systems for providing a consistent flow of fluid through lumens of a delivery apparatus are disclosed. As one example, a delivery apparatus can include an outer shaft configured to retain a prosthetic implant in a delivery configuration, an inner shaft disposed within the outer shaft and configured to interface with an end of the prosthetic implant and move axially relative to the outer shaft, and a sleeve shaft disposed within the outer shaft and configured to cover the prosthetic implant in the delivery configuration. In some examples, the inner shaft can include one or more openings defined therein that extend between an inner surface and an outer surface of the inner shaft and that are configured to fluidly couple an inner lumen of the inner shaft with a lumen disposed between the outer surface of the inner shaft and an inner surface of the sleeve shaft.
