Claim 10:
11. A delivery device for a collapsible prosthetic heart valve, the delivery device comprising:
an inner shaft;
an outer shaft; and
a distal sheath disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft, the compartment being sized to receive the prosthetic heart valve, the inner shaft and the distal sheath being movable relative to one another, the outer shaft and the distal sheath sharing a central longitudinal axis;
wherein the outer shaft is joined to the distal sheath via a joint so that the distal sheath is capable of rotation about the central longitudinal axis while the outer shaft remains static relative to the central longitudinal axis,
wherein the distal sheath includes a fin extending radially outward therefrom, the fin being configured to rotate in a single rotational direction upon exposure to blood flowing across the fin from a distal end of the fin toward a proximal end of the fin.
