  • Publication number: 20180326181
    Abstract: The present application is related to devices, systems, and methods for controlling active drive systems. In one embodiment, the drive system may include a first surface and a second surface for engaging an elongate member. The first and second surfaces may be attached to a drive mechanism to move the elongate member. The first surface may be slidable relative to the drive mechanism and may have a clearance between the drive mechanism and an end of the first surface during movement of the elongate member in a non-slip condition. A sensor may be associated with the first surface and may be configured to detect movement of the first surface in a slip condition.

  • Patent number: 10123843
    Abstract: An input device includes a plurality of orientation blocks each representing a portion of a catheter assembly and a controller configured to determine an orientation of the plurality of orientation blocks relative to one another. The controller is further configured to output a control signal that causes a tip of a catheter assembly to adopt the orientation determined by the controller. A system includes an actuator configured to manipulate a position and orientation of the catheter assembly. The controller of the input device is configured to output a control signal to the actuator to make a tip of a catheter assembly adopt the orientation determined by the controller. The input device can be virtually represented on a computing device.

  • Patent number: 9827061
    Abstract: A command interpreter is in communication with a wireless controller. The command interpreter is configured to identify a reference location of the wireless controller, identify a second location of the wireless controller, and determine, based on the reference location and the second location, a sequence of instrument commands configured to adjust positioning of the instrument device.

  • Publication number: 20150375399
    Abstract: An exemplary illustration of a user interface for a medical robotics system may include multiple light sources configured to illuminate a gesture within a field of view. The user interface may further include multiple cameras, which have a field of view and are configured to generate a detection signal in response to detecting the gesture within the field of view. The user interface can also have a controller configured to generate a command signal based on the detection signal. The command signal may be configured to actuate an instrument driver, a display device, a C-arm configured or any combination thereof to perform a function mapped to the gesture.

  • Patent number: 9173713
    Abstract: A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter. The present embodiment further contemplates a robotic surgical method for the articulation of a steerable catheter wherein an input device is manipulated to communicate a desired catheter position to a control computer and motor torque commands are outputted to an instrument driver.

  • Publication number: 20140276392
    Abstract: An input device for a robotic catheter system includes an inner member having a generally cylindrical shape and defining an axis, and an outer member coaxially disposed on the inner member and configured to rotate about and move along the axis defined by the inner member to control a position and orientation of at least one of a catheter and a guide wire. Rotating the outer member about the axis causes the catheter, the guide wire, or both, to rotate and wherein moving the outer member along the axis causes the catheter, the guide wire, or both, to advance or retract relative to a patient's body.
