Devices and Methods for Percutaneous Tricuspid Valve Repair

A method for repairing a tricuspid valve of a patient's heart comprising:

• positioning a locating catheter through a tricuspid valve into the right ventricle;
• slidably disposing a multi-lumen translation catheter within a lumen of the locating catheter, the multi-lumen translation catheter including a first catheter member and a second catheter member;
• positioning a distal end of the first catheter member at a first location;
• expanding the second catheter member of the multi-lumen translation catheter and positioning a distal end of the second catheter member against the tricuspid annulus at a second location;
• advancing first and second wire delivery catheters into the right atrium with distal ends of the first and second wire delivery catheters opposing the distal ends of the first and second catheter member, and contacting the tricuspid annulus inside the right atrium at the first and second locations;
• advancing distal ends of first and second wires the first and second wire delivery catheters, respectively, from the right atrium across the tricuspid annulus to the right ventricle at the first and second locations, respectively;
• tracking the first and second tissue anchor delivery catheters over the first and second wires, crossing the tricuspid annulus with distal ends of the first and second tissue anchor delivery catheters being disposed inside the right ventricle;
• deploying first and second tissue anchors with distal portions of the first and second tissue anchors being positioned against the tricuspid annulus from inside the right ventricle, and proximal portions of the first and second tissue anchors being positioned against the tricuspid annulus from inside the right atrium;
• and plicating tissue of the tricuspid annulus by reducing the distance between the first and second tissue anchors.
