Tissue Anchors and Percutaneous Tricuspid Valve Repair Using A Tissue Anchor

摘要

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.

主权项

1. A method comprising:
locating a first location near a heart valve annulus; deploying a distal portion of a first tissue anchor across the heart valve annulus at the first location; deploying a proximal portion of the first tissue anchor at the first location; locating a second location near the heart valve annulus; deploying a distal portion of a second tissue anchor across the heart valve annulus at the second location; deploying a proximal portion of the second tissue anchor at the second location;
wherein the first tissue anchor and the second tissue anchor are connected with a continuous portion of a flexible tensioning member; and changing the distance between the first and second tissue anchors.
