Benefits of technology
The patent text describes a method for reducing the circumference of a tricuspid annulus in the heart. The method involves positioning a wire delivery catheter in the right ventricle and advancing wires through the tricuspid valve and into the right atrium. The wires are then captured and extended outside the body. A second tissue anchor delivery catheter is then advanced over the first wire and positioned against the tricuspid annulus in the right ventricle or atrium. The wires are then deployed and the tissue anchors are secured to the tricuspid annulus. The method can be used to treat various heart conditions, such as tricuspid valve regurgitation or patent text describes a method for reducing the circumference of a tricuspid annulus in the heart. The method involves positioning a wire delivery catheter in the right ventricle and advancing wires through the tricuspid valve and into the right atrium.

Problems solved by technology
Tricuspid valve diseases relate to conditions in which the valve between the two right heart chambers (i.e., the right ventricle and the right atrium) doesn't function properly and these diseases often occur with other heart valve problems.

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, placing a wire across the tricuspid annulus at such an identified location, deploying a tissue anchor across such an identified location, deploying two or more tissue anchors and coupling the tissue anchors with a flexible tensioning member, and applying tension to a flexible tensioning member that is coupled with the two or more tissue anchors, plicating tissues between each pair of the two or more tissue anchors, and reducing the circumference of the tricuspid annuls. As a result, a regurgitation jet is reduced or eliminated.
Description
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 14 / 662,203, filed Mar. 18, 2015, the entire contents of which is incorporated by reference herein as if expressly set forth in its respective entirety herein.FIELD[0002]The present teachings generally relate to new tissue anchors and uses thereof in percutaneous valve repair.BACKGROUND[0003]Tricuspid valve diseases relate to conditions in which the valve between the two right heart chambers (i.e., the right ventricle and the right atrium) doesn't function properly and these diseases often occur with other heart valve problems. Examples of tricuspid valve diseases include tricuspid valve regurgitation, tricuspid valve stenosis, tricuspid valve atresia, and the Ebstein's anomaly. In tricuspid valve regurgitation, the tricuspid valve doesn't close properly and blood flows back into the right atrium; in tricuspid valve stenosis, the tricuspid valve is narrowed and red...
