    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.

    摘要: A deployment device for deploying a material into a patient, said deployment device having a housing and a placement device including a retracted condition within the housing for holding a material, in a collapsed condition, within the housing and an extended condition from the housing for disposing and releasing the material at a predetermined site in an uncollapsed condition. A method of deploying a material by placing the placement device in an extended condition and affixing the material to the extended placement device, retracting the placement device into the housing with the material in a collapsed condition, extending the placement device, and placing the material at a predetermined site in an uncollapsed condition.
