Claim 0:
1. A delivery device for implantation of a prosthetic heart valve within a heart, the prosthetic heart valve being radially expandable from a radially compressed state to a radially expanded state, the delivery device comprising:
a handle;
a catheter comprising a proximal end portion and a distal end portion, wherein the proximal end portion of the catheter is coupled to the handle, and wherein the distal end portion of the catheter is configured to be inserted into a patient's body;
an inflatable balloon positioned adjacent the distal end portion of the catheter;
an inner shaft extending from the handle and comprising a distal portion positioned within the balloon, wherein the inner shaft comprises a first outer diameter;
a mounting member fixedly coupled to the distal portion of the inner shaft and disposed within the balloon, wherein the mounting member comprises a sealed section and an unsealed section, wherein the sealed section is axially longer than the unsealed section and comprises an inner lumen and an at least substantially cylindrical outer surface, wherein the inner lumen at least partially defines a fluid pathway that allows balloon inflation fluid to flow axially through the sealed section to the unsealed section and that restricts the balloon inflation fluid from flowing radially outwardly from the inner lumen to the at least substantially cylindrical outer surface, wherein the sealed section comprises at least substantially cylindrical outer surface extending axially in a straight line in a direction parallel to a longitudinal axis of the mounting member, wherein the at least substantially cylindrical outer surface is configured for receiving the prosthetic heart valve in the radially compressed state and defines a second outer diameter that is greater than the first outer diameter of the inner shaft, and wherein the unsealed section comprises at least one opening extending radially through the mounting member such that the balloon inflation fluid flowing through the fluid pathway can exit the mounting member and flow into the balloon when the prosthetic heart valve is mounted over the balloon and the mounting member in the radially compressed state; and
a distal stop at least partially positioned within the balloon and at least partially axially overlapping both the distal portion of the inner shaft and the mounting member, the distal stop configured to be positioned adjacent a distal end of the prosthetic heart valve when the prosthetic heart valve is mounted over the balloon and the mounting member in the radially compressed state.
