Benefits of technology

This patent describes a way to fix a damaged heart valve called a mital valve. It uses two different tools that can be applied separately to the valve's edges. One tool has a suction cup to hold the edge of the valve in place, and it also has something like a screw or staple to attach it securely to the wall of the heart. Then, after releasing the first part of the valve, the other tool comes along and does the same thing to the other side of the valve. Once both parts have been fixed, they pull tightly together which helps improve how well the valve works.

Problems solved by technology

The technical problem addressed in this patent text is the need for new methods to treat heart valve regurgitation in a minimally invasive way. Current surgical techniques are effective but traumatic for patients, and existing minimally invasive procedures have limitations in terms of the strength of the treatment and the anatomy of the heart. Therefore, there is a need for further approaches to treat heart valve regurgitation.

Abstract

Devices and methods for reshaping a mitral valve annulus are provided. One preferred device is configured for deployment in the right atrium and is shaped to apply a force along the atrial septum. The device causes the atrial septum to deform and push the anterior leaflet of the mitral valve in a posterior direction for reducing mitral valve regurgitation. Another preferred device is deployed in the left ventricular outflow tract at a location adjacent the aortic valve. The device is expandable for urging the anterior leaflet toward the posterior leaflet. Another preferred device comprises a tether configured to be attached to opposing regions of the mitral valve annulus.
