Patent number: 5971976Abstract: A system for maintaining a substantially fixed distance between a localized surface of the heart and the distal end of a surgical device for use in endoscopic surgical procedures. The system comprises a stabilizer for minimizing localized motion of the heart in attached communication with a sensor for sensing localized motion of the heart in a region proximal the stabilizer and a controller in electrical communication with the sensor for processing data indicative of the localized motion of the heart in a region proximal the stabilizer. The processor is in electrical communication with a controller for a robotic arm that holds an instrument for use in an endoscopic surgical procedure, said instrument having a proximal and distal end, and said robotic arm in electrical communication with the controller.Type: GrantFiled: January 28, 1998Date of Patent: October 26, 1999Assignee: Computer Motion, Inc.Inventors: Yulun Wang, Kenneth Grace, Darrin R.
