摘要： A catheter system allows for percutaneous intervention on the fast-moving structures inside the heart. The device consists of a steerable catheter sheath, an actuated, multi-degree of freedom moving catheter, and a catheter end effector, such as a fixation device. An actuator controls the motion of the catheter guide-wire in the catheter sheath to follow the motion of the target tissue. A control system controls the actuator and compensates for mechanical characteristics of the system including friction and backlash. A 3-D imaging system can be used to view the motion of the target tissue and the catheter end effector and produce 3-D imaging data. The 3-D imaging data can be used by the control system to track the target tissue and accurately position the end effector with respect to the moving target tissue allowing a clinician to repair the target tissue while it is moving. The system can be used to perform mitral valve annuloplasty wherein the actuated catheter compensates for the heart valve motion and an end effector fixation device is used to place fixation items, like anchors or staples, into the heart valve tissue to fix the annulus.
