Abstract

A method is provided for reducing tricuspid valve regurgitation of a patient. The method includes implanting a first tissue anchor at a first implantation site in cardiac tissue in the vicinity of the tricuspid valve of the patient, and implanting a second tissue anchor at a second implantation site in cardiac tissue of the patient opposite the first implantation site across the tricuspid valve. Using a spool that winds therewithin at least a portion of a longitudinal member that couples the first and the second tissue anchors together, tension is applied between the first and the second tissue anchors to alter the geometry of the tricuspid valve by rotating the spool.

Claims

1. A method of reducing tricuspid valve regurgitation of a patient, the method comprising:

implanting a first tissue anchor in the wall of the atrium above the annulus at an anterior leaflet or at a commissure between an anterior leaflet and a posterior leaflet at;

implanting a second tissue anchor in the wall of the atrium above the annulus at a septal leaflet opposite the anterior leaflet at across the tricuspid valve; and

using a spool that (a) winds therewithin at least a portion of a longitudinal member that couples the first and the second tissue anchors together and (b) is suspended along the longitudinal member hovering over the tricuspid valve away from the first and the second tissue anchors, applying tension between the first and the second tissue anchors to achieve bicuspidization of the tricuspid valve by rotating the spool.

2. The method according to claim 1, wherein the first and the second tissue anchors comprise respective helical tissue anchors.
