Abstract
A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.

A method of positioning a valve prosthesis at a site of a native valve, wherein the native valve is a mitral valve, the method comprising the steps of:
- advancing a delivery system through the native valve and into a chamber of the heart, wherein the delivery system includes a shaft, an anchoring component removably coupled to the shaft, the valve prosthesis disposed on a distal portion of the shaft in a radially collapsed configuration, and a tether component having a first end non-removably coupled to the anchoring component and a second end non-removably coupled to the valve prosthesis, wherein the step of advancing the delivery system through the native valve comprises advancing the delivery system through the mitral valve and into the left ventricle of the heart;
- advancing the delivery system to a right atrium of the heart prior to the step of advancing the delivery system through the native valve;
- advancing the delivery system through an interatrial septum to a left atrium of the heart;
- advancing at least a portion of the anchoring component through the wall of the heart, wherein the step of advancing the anchoring component through the wall of the heart comprises advancing the anchoring component through a wall of the left ventricle;
- positioning the anchoring component against an outer surface of the heart wall;
- releasing the anchoring component from the delivery system;
- and
- deploying the valve prosthesis to a radially expanded configuration at the site of the native valve, wherein the valve prosthesis is deployed at a spaced apart location from the anchoring component and the tether component extends between the valve prosthesis deployed at the site of the native valve and the anchoring component positioned against the outer surface of the heart wall.
A method of positioning a prosthesis at a site of a native valve, the method comprising the steps of:
- advancing a delivery system through the native valve and into a chamber of the heart, wherein the delivery system includes a shaft, an anchoring component removably coupled to the shaft, a prosthesis disposed on a distal portion of the shaft in a radially collapsed configuration, and a tether component having a first end non-removably coupled to the anchoring component and a second end non-removably coupled to the prosthesis, wherein the anchoring component forms a distal tip of the delivery system during the step of advancing the delivery system through the native valve;
- advancing at least a portion of the anchoring component through the wall of the heart;
- positioning the anchoring component against an outer surface of the heart wall;
- releasing the anchoring component from the delivery system;
- and
- deploying the prosthesis to a radially expanded configuration at the site of the native valve, wherein the prosthesis is deployed at a spaced apart location from the anchoring component and the tether component extends between the prosthesis deployed at the site of the native valve and the anchoring component positioned against the outer surface of the heart wall.
