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.

An exemplary drive apparatus may include a roller assembly and a roller support. The roller assembly may have a first continuous surface, a second continuous surface, an open configuration for receiving an elongate member, and a closed configuration for securing the elongate member in the roller assembly. The roller assembly imparts axial motion to the elongate member along the first continuous surface, which maintains contact with the elongate member during the axial motion. The roller support rotates the roller assembly about the second continuous surface, which maintains contact with the roller support during rotational motion. The roller assembly and roller support to impart axial and rotational motion, respectively, independently of one another.

The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.

For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.

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
Hansen Medical | Date: 2016-12-23

A robotic instrument driver for elongate members includes a first elongate member, and at least one manipulator mechanism configured to manipulate the first elongate member, and at least one articulating drive configured to articulate the first elongate member, positionable on a bed and beside a patient access site. The manipulator and articulating drive are positioned relative to each other a distance less than the insertable length of the first elongate member, stationary in position.

A device may operate a guide wire and be operable by a single operator digit. The device may include an insertion control device for advancing the guide wire in a forward and in a reverse direction and along a longitudinal axis of the guide wire; and a rotary device for rolling a guide wire about the longitudinal axis. A robotic instrument driver may be operatively coupled to the device and configured to control axial movement of the guide wire along the longitudinal axis according to input received from the insertion control device and to control rotational movement of the guide wire according to input received from the rotary device.


Patent
Hansen Medical | Date: 2017-06-07

A medical system includes a first flexible elongate member having a steerable distal section and a lumen, and an elongate member holder having a first component and a second component that is moveable relative to the first component, the first and second components configured to cooperate with each other to grip a second flexible elongate member positioned in the lumen of the first elongate member, wherein the first and second components are configured to cooperate with each other in a first mode of operation to translate the second elongate member along a longitudinal axis of the second elongate member, and to cooperate with each other in a second mode of operation to rotate the second elongate member about the longitudinal axis of the second elongate member.


Patent
Hansen Medical | Date: 2016-11-30

Systems and methods for driving a flexible medical instrument to a target in an anatomical space with robotic assistance are described herein. The flexible instrument may have a tracking sensor embedded therein. An associated robotic control system may be provided, which is configured to register the flexible instrument to an anatomical image using data from the tracking sensor and identify one or more movements suitable for navigating the instrument towards an identified target. In some embodiments, the robotic control system drives or assists in driving the flexible instrument to the target.
