Methods for delivering prosthetic valves to native heart valves
First Claim
1. A method, comprising:
- advancing a self-expandable support structure and a self-expandable prosthetic heart valve into a patient'"'"'s heart using a delivery apparatus and a transapical delivery approach, wherein the support structure and the prosthetic heart valve are in a radially compressed state;
positioning the support structure on or adjacent a surface of an outflow side of the patient'"'"'s native aortic valve using the delivery apparatus;
radially expanding the support structure from the compressed state to a fully expanded state, the support structure having a support-structure interior;
positioning the prosthetic heart valve radially within the support-structure interior and within the patient'"'"'s native aortic valve using the delivery apparatus;
radially expanding the prosthetic heart valve from the compressed state to an expanded state while the prosthetic heart valve is in the support-structure interior and while the support structure is in the fully expanded state; and
releasing the support structure from the delivery apparatus after the prosthetic heart valve is radially expanded.

Abstract
Representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve are disclosed. In one embodiment, for instance, a support structure and an expandable prosthetic valve are delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior) via a delivery system. The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable, prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

11. A method, comprising:
-
advancing an expandable support structure and an expandable prosthetic heart valve into a patient'"'"'s heart using a single delivery apparatus, wherein the support structure and the prosthetic heart valve are in a radially compressed state; positioning the support structure on or adjacent a surface of an outflow side of a native heart valve of the patient using the delivery apparatus; radially expanding the support structure from the compressed state to a fully expanded state, the support structure having a support-structure interior, wherein the support structure is self-expandable; positioning the prosthetic heart valve radially within the support-structure interior and within the patient'"'"'s native heart valve using the delivery apparatus; and radially expanding the prosthetic heart valve from the compressed state to an expanded state while the prosthetic heart valve is in the support-structure interior and while the support structure is in the fully expanded state, wherein the prosthetic heart valve is self-expandable, and wherein the act of radially expanding the prosthetic heart valve causes one or more native leaflets of the native heart valve to be captured between the support structure and the prosthetic heart valve. - View Dependent Claims (12, 13, 14, 15)

16. A method, comprising:
-
advancing a delivery apparatus into a patient'"'"'s heart, wherein an expandable support structure and an expandable prosthetic heart valve are mounted at spaced-apart locations along a distal end portion of the delivery apparatus in a radially compressed state, wherein the support structure and the prosthetic heart valve are self-expandable and are advanced together in the same direction toward the patient'"'"'s heart on the delivery apparatus; positioning the support structure at or adjacent a native heart valve of the patient using the delivery apparatus; radially expanding the support structure from the compressed state to a fully expanded state, wherein the support structure remains coupled to the delivery apparatus after the support structure is expanded; positioning the prosthetic heart valve radially within the support structure and within the patient'"'"'s native heart valve using the delivery apparatus; radially expanding the prosthetic heart valve from the compressed state to an expanded state while the prosthetic heart valve is radially within the support structure and while the support structure is in the fully expanded state; and releasing the support structure from the delivery apparatus after the prosthetic heart valve is radially expanded. - View Dependent Claims (17, 18, 19, 20)
