FLEXIBLE ACTUATOR MANDREL FOR TISSUE APPOSITION SYSTEMS
First Claim
1. A system for approximating tissue, said system comprising:
- a delivery catheter having a lumen extending therethrough;
an actuator rod disposed at least partially in the lumen, and having a proximal end and a distal end;
a flexible cable at least partially disposed in the lumen, the flexible cable having a proximal end and a distal end, wherein the proximal end of the flexible cable is coupled to the distal end of the actuator rod, and wherein the flexible cable is resiliently biased to return to a substantially linear configuration after being deflected 90°
or more;
a coupler coupled to the distal end of the flexible cable; and
an implantable fixation device releasably attached to the coupler.

Abstract
The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.
