1. A delivery device for a collapsible prosthetic heart valve, comprising:
a catheter assembly comprising:
an inner shaft around which a compartment is defined, the compartment being adapted to receive the prosthetic heart valve in an assembled condition;
an outer shaft assembled over the inner shaft and adapted to slide relative to the inner shaft along a longitudinal axis thereof;
a distal sheath connected to a distal end of the outer shaft and slidable therewith, the distal sheath being adapted to selectively cover and uncover the compartment and the prosthetic heart valve when the prosthetic heart valve is in the assembled condition; and
an outer tube assembled over the outer shaft; and
an alignment and stabilization device having a collapsed condition and an expanded condition, the alignment and stabilization device having one end connected to the outer shaft proximally of the compartment so that the alignment and stabilization device is slidable in a longitudinal direction relative to the outer shaft,
wherein the outer tube is adapted to slide relative to the outer shaft to selectively cover and uncover the alignment and stabilization device.
