Abstract
Delivery apparatuses including crimp balloons that can be selectively pressurized, compressed, or folded over themselves, to enable torque transfer between a balloon shaft and inflatable balloon of the delivery apparatus are described. A delivery apparatus for a prosthetic device can comprise a first shaft, a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end of the first shaft, an inflatable balloon arranged around the distal end portion of the second shaft, a crimp balloon extending at least partially between the first shaft and inflatable balloon, and a seal disposed between an interior of the crimp balloon and an interior of the inflatable balloon. The seal is configured to fluidly separate the interiors of the crimp balloon and the inflatable balloon in a first state and allow fluid communication from the crimp balloon to the inflatable balloon in a second state.
