  • Publication number: 20250231628
    Abstract: A system comprises: an input device to generate commands for controlling a medical device; and an operator-detection sensor to generate sensor data indicating an operator's presence/absence at the input device. Movement of the medical device is controlled based on a comparison of the data with a baseline and a command line. The medical device is not moved when a comparison with a first baseline indicates the operator's absence, and the device is moved when a comparison with a first command line indicates the operator's presence. A triggering event is detected for a calibration procedure, which comprises establishing a second baseline associated with the operator's absence and establishing a second command line associated with the operator's presence. The medical device is not moved when a comparison with the second baseline indicates the operator's absence, and the device is moved when a comparison with the second command line indicates the operator's presence.

  • Publication number: 20240215985
    Abstract: The present disclosure relates to repair devices configured for use in fixing or approximating tissues, such as cardiac valve tissues and particularly the leaflets of a regurgitant mitral valve. The repair device includes a shaft, a pair of proximal elements pivotally coupled to the shaft and extending from the shaft, and a pair of distal elements pivotally coupled to the shaft and extending from the shaft. The proximal and distal elements are configured so that targeted tissue can be grasped therebetween. The distal elements and/or the proximal elements include adjustable arms that can be extended and retracted to adjust the length of the gripping elements to provide more effective grasping of targeted tissues.

  • Patent number: 11934594
    Abstract: Systems and methods for operation of a medical device may include at least two sensors to confirm a command to control a medical instrument is intentionally made by an operator. The systems may include an operator-detection sensor associated with an input device and configured to detect a presence of an operator at the input device. The systems may also include a motion sensor associated with the input device and configured to detect a displacement distance of the input device. A control unit may use a displacement threshold for the input device and may be configured to permit or prevent control signal generation based on feedback from the at least two sensors.
