Patent number: 8601185Abstract: The disclosed system and methods involve controlling the timing and order in which numerous motors and sensors exchange data over a data bus. The method can be used with, for example, motion control, automotive, industrial automation, and medical equipment applications using data buses. As an example of one possible medical equipment application, the method of exchanging data on a bus can be used with a remote catheter guidance system. The disclosed system and methods help optimize data exchange over a bus and avoid collisions by grouping the transmission of sensor readings, by grouping the transmission of motor commands, and by predetermining the order of these groups. Further, the method provides a way of ensuring that incomplete data sets are not exchanged over the bus. The method also provides a way of synchronizing motor actuation based on data transmitted to the data bus.Type: GrantFiled: December 30, 2010Date of Patent: December 3, 2013Assignee: St. Jude Medical, Atrial Fibrillation Divison, Inc.Inventors: Kulbir S.

Publication number: 20120158011Abstract: A robotic catheter control system includes a proximity sensing function configured to generate a proximity signal that is indicative of the proximity of the medical device such as an electrode catheter to a nearest anatomic structure such as a cardiac wall. The control system includes logic that monitors the proximity signal during guided movement of the catheter to ensure that unintended contact with body tissue is detected and avoided. The logic includes a means for defining a plurality of proximity zones, such as a GREEN, YELLOW and RED designated zones, each having associated therewith a respective proximity (distance) criterion, with the RED zone being the nearest to the body tissue and the YELLOW zone being the next nearest to the body tissue. When the logic detects entry of the catheter into the RED zone, the logic terminates the operating power to the actuation units of the control system, to thereby stop movement of the catheter entirely.Type: ApplicationFiled: December 16, 2010Publication date: June 21, 2012Inventors: Kulbir S.
