Abstract

Described herein are methods and apparatus for approximating targeted tissue by intertwining two or more sutures together. The sutures are attached to the targeted tissue and routed to a twister device. The twister device secures end portions of the sutures and twists them to intertwine the sutures. Controlling the number of twists provides control over the forces applied to the targeted tissue. In conjunction with visualization feedback, real-time adjustments can be made to achieved targeted results, such as elimination of mitral regurgitation when the disclosed methods and apparatus are applied to mitral valve repair.

Claims19

Dependent claims

A method for twisting sutures together to approximate anchor implants attached to targeted tissue, the method comprising:

attaching two or more cords to targeted tissue, each of the two or more cords including a distal anchor implant and a suture extending proximally from the distal anchor implant;
securing proximal end portions of the sutures of the two or more cords to a twister device;
operating the twister device to cause the sutures of the two or more cords to intertwine;
releasing the proximal end portions of the sutures of the two or more cords from the twister device;
and
anchoring the proximal end portions of the sutures of the two or more cords to prevent unwinding of the sutures of the two or more cords.
