1. A prosthetic heart valve delivery system comprising:
a delivery device including:
an inner shaft;
an outer shaft;
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 in a collapsed condition, the inner shaft and the distal sheath being movable relative to one another; and
a guidewire having a proximal section, a distal anchoring section, and an annulus section between the proximal section and the distal anchoring section;
wherein the annulus section of the guidewire has a non-circular cross-sectional shape, the cross-sectional shape being taken along a plane that is transverse to a central longitudinal axis of the annulus section of the guidewire, that matches a non-circular cross-sectional shape of an interior guidewire lumen of the delivery device, the annulus section of the guidewire twisting along a length of the annulus section.
