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 1):
A method, comprising:\n inserting a distal end portion of a delivery apparatus and a prosthetic valve into a body of a patient, the delivery apparatus having a handle, a first shaft having a proximal end portion and a distal end portion, a second shaft extending coaxially through the first shaft and having a proximal portion and a distal end portion, the proximal 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, the prosthetic valve comprising a metallic stent and a flexible valvular structure mounted within the stent, wherein 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 portion of the prosthetic valve retained within the valve cover, wherein the nose piece comprises an abutment member disposed within an interior bore of the nose piece and having an abutment surface engaging the inlet end portion of the prosthetic valve so as to limit axial movement of the prosthetic valve within the bore of the nose piece; advancing the delivery apparatus through the patient's vasculature until the radially compressed prosthetic valve is positioned within the native aortic annulus; retracting the first shaft relative to the second shaft so as to retract the valve cover relative to the outflow end portion of the prosthetic valve; advancing the second shaft distally relative to the first shaft by turning 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.
