Abstract: A system configured to control an endoscope probe either in manual mode or in robotic mode. The system comprises: a handle at a proximal end of the probe; a handheld controller attachable to the handle; and a robotic controller in communication with the handle and/or the handheld controller. The handheld controller includes separate controls for the manual and robotic modes. In manual mode, the handheld controller combined with the handle and the probe is used to manually control insertion and actuation of the probe into a first location of a lumen. In robotic mode, the handheld controller is removed from the handle, and the robotic controller controls handle to robotically navigate the probe to a second location within the lumen. Attachment and detachment of handheld controller to the handle is such that only certain controls appropriate to a particular portion of a workflow are accessible to the user.

Abstract: In a robot-assisted steerable medical device, such as a catheter, a magnetic connector hub is configured to establish mechanical and magnetic connection between a drive cable and an actuator, or between multiple modules in a single insert-and-twist motion. The connector hub creates a magnetic breakaway feature for automatically decoupling the actuator from the drive cable, while the catheter remains attached. This prevents damage to the catheter/tool and/or patient when an excessive force is applied, and adds a safety element and helps protect the patient. And when the breakaway occurs the system can be automatically reengaged catheter without damage, so that normal operation can resume. Connection can also be broken at any point in the operation based on threshold forces or emergency situations.

Abstract: A medical system including a medical device having an outer diameter, a display device, and a controller. The controller is configured to acquire data regarding a biological lumen such as an airway structure, acquire an image of the airway structure, generate an overlay representing the outer diameter of the medical device, and display, on the display device, the overlay representing the outer diameter of the medical device on the acquired image of the airway structure. The overlay is scaled relative to a diameter of the airway structure at a focal plane of the airway structure based on the acquired data.

Abstract: One or more devices, systems, methods and storage mediums for performing medical procedure (e.g., needle guidance, ablation, biopsy, etc.) planning and/or performance, and/or for performing registration using at least one mask, are provided. Examples of applications for such devices, systems, methods and storage mediums include imaging, evaluating and diagnosing biological objects, such as, but not limited to, lesions and tumors, and such devices, systems, methods and storage mediums may be used for radiotherapy applications (e.g., to determine whether to place seed(s) for radiotherapy). The devices, systems, methods and storage mediums provide improved registration results by utilizing at least one mask to suppress one or more artifacts or objects (which may or may not include, but is not limited to, at least one medical instrument or tool) in an image including a portion of the medical guidance device and/or to enhance a region or target of interest in the image.

Abstract: Disclosed herein are planning, navigation and simulation systems and methods for minimally invasive image-guided percutaneous intervention in which the planning method and system use patient-specific pre-operative images and instrument-specific parameters to generate a planned insertion path. A system includes a needle guide device that interfaces with a computing device to guide a needle-like probe towards target location within an anatomy of a subject. The computing device includes a processor configured to receive volumetric image data of the anatomy of the subject, and data about parameters of the needle guide device. One or more algorithms executed by the processor provide direct visualization of a parametric contour map superposed on an image of the patient's skin surface. A user can choose an optimal insertion point for the planned insertion path based the parametric contour map.
