Abstract:
An assembly includes a prosthetic heart valve and a delivery apparatus for implanting the prosthetic heart valve within the native aortic valve of a patient. The prosthetic heart valve has a radially compressible and expandable metallic stent and a flexible valvular structure mounted within the stent. The delivery apparatus has a handle, a first shaft having a proximal end portion and a distal end portion, a second shaft extending co-axially through the first shaft and having a proximal end portion and a distal end portion, the proximal end portions of the first and second shafts extending distally from the handle, a valve cover coupled to the distal end portion of the first shaft, and a nose piece coupled to the distal end portion of the second shaft.

Claim (Index 8):
A method, comprising:\n inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the vasculature of a patient, the delivery apparatus comprising a handle, first and second shafts extending from the handle, the second shaft extending coaxially through the first shaft, a valve cover coupled to a distal end portion of the first shaft, and a nose piece coupled to a distal end portion of the second shaft, wherein the prosthetic valve comprises a metallic stent and a flexible valvular structure mounted within the stent and the prosthetic valve is radially crimped around the second shaft with an inlet end portion of the prosthetic valve retained within the nose piece and an outlet end of the prosthetic valve retained within the valve cover; advancing the distal end portion of the delivery apparatus and the prosthetic valve through the patient's vasculature until the prosthetic valve is positioned within the native aortic annulus, wherein a retaining mechanism of the delivery apparatus retains the second shaft and the nose piece from moving relative to the handle during the act of advancing; retracting the first shaft relative to the second shaft so as to retract the valve cover relative to the distal end portion of the prosthetic valve; unlocking the retaining mechanism to permit axial movement of the second shaft relative to the handle; advancing the second shaft distally relative to the first shaft and the handle using an adjustment knob of the delivery apparatus to advance the nose piece distally relative to the inflow end portion of the prosthetic valve; and radially expanding the prosthetic valve within the native aortic annulus.
