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.
