AI Technical Summary

Problems solved by technology

Ultrasound imaging methods do a good job of showing tissue sections, but do a poor job of showing the position of interventional tools relative to the imaged tissue
In contrast, fluoroscopy imaging is good at showing tool position but poorly imaging tissue

Embodiment Construction

[0062] As used herein and in the claims, the phrase "annulus" refers to the annular tissue structure surrounding the opening at the base of a heart valve, which supports the leaflets of the valve. For example, the annulus of the mitral valve, tricuspid valve, aortic valve, pulmonary valve, venous valve, and other valve annulus in the body. In the mitral valve, the annulus is usually a saddle-shaped structure that supports the leaflets of the mitral valve.

[0063] As used herein and in the claims, the phrase "peripheral wall" applied to the annulus refers to the surface or portion of the tissue of the annulus, and / or the portion of tissue adjacent to the annulus.

[0064]As used herein and in the claims, "recess" refers to a depression or pit formed in the surface of a template. The recess may comprise flat areas connected at an angle, for example rectilinear, but will more typically have a curved bottom incorporating a pair of generally straight and / or curved walls or legs. ...

Abstract

A system for reshaping an annulus includes an elongate template having a length along a longitudinal axis, and at least one recess in a generally transverse direction along the length. The pre-formed template is positioned against at least one region of an inner peripheral wall of the annulus, and at least one anchor on the template advances into a sidewall of the annulus to reposition at least a section of the region of the inner peripheral wall of the annulus into the recess. In this manner, the circumferential length of the annulus may be shortened and / or remodeled to improve mating of the valve leaflets and / or eliminate or reduce regurgitation of the valve.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional No. 62 / 871,916 (Attorney Docket No. 32016-718.101), filed July 9, 2019, and is the basis of U.S. Patent Application No. 16 / 740,172, filed January 10, 2020 (Attorney Docket No. Docket No. 32016-717.501), the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to medical devices and methods, particularly those in the field of cardiology. More specifically, the present invention relates to systems and methods for accessing heart valves for treatment, repair or replacement. Background technique [0004] Heart valves perform important biological functions, have a wide range of anatomical configurations, including shape, design and size, and are susceptible to a variety of different conditions, such as disease conditions that may result in injury or dysfunction. For example, the mitral valve ...
