  • Publication number: 20210077195
    Abstract: The present disclosure provides a system and method for controlling an articulating member including a tool. The system may include a dual camera system that captures near-infrared (NIR) images and point cloud images of a tissue or other substance that includes NIR markers. The system may generate a three-dimensional (3D) path based on identified positions of the NIR markers, may filter the generated path, and may generate a 3D trajectory for controlling the articulated arm of a robot having a tool to create an incision along the filtered path. In a shared control mode, an operator may generate manually control commands for the robot to guide the tool along such a path, while automated control commands are generated in parallel. One or more allocation functions may be calculated based on calculated manual and automated error models, and shared control signals may be generated based on the allocation functions.

  • Patent number: 10925474
    Abstract: The present disclosure is a device and method associated with the delivery of medical devices in the pericardial space using a minimally invasive approach with direct visualization. More specifically, the device can be used to deliver permanent pacing, defibrillation and cardiac resynchronization leads, as well as leadless pacemakers for cardiac rhythm management to the epicardial surface of the heart. A subxiphoid procedure is proposed as a minimally invasive alternative to thoracotomy, while the delivery tool incorporates a camera for direct visualization of the procedure. The tool also incorporates a steerable catheter to provide selective control of the placement and orientation of the medical device in the pericardial space.
