Abstract
A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be 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 may be movable relative to one another. The delivery device may also include a tube member and an outer sleeve overlying the tube member. The tube member may be configured to rotate or twist upon axial movement of the outer sleeve with respect to the tube member, the rotation or twisting of the tube member configured to rotate the prosthetic heart valve when the prosthetic heart valve is received within the compartment in the collapsed condition.
