Abstract: A snare tool manipulator system includes an elongated flexible device having a length and including a distally mounted end effector configured to perform a task. The flexible device is operable to manipulate the end effector in order to perform the task. The system also includes an elongated snare tool including a distally mounted snare device configured for grasping the flexible elongated member at a position along its length. The snare tool is operable robotically to manipulate the flexible device which in response manipulates the end effector.

Abstract: A surgical robot system includes a support structure for positioning relative to a patient. The support structure includes a plurality of mounting structures. One or more robotic tool cassettes that are configured to interchangeably connect with any of the mounting structures. Each tool cassette includes a concentric tube manipulator and a transmission for operating the concentric tube manipulator. The support structure also includes a tube collector including a tube assembly associated with each of the mounting structures. The tube assemblies are configured to receive the concentric tube manipulators and guide the manipulators to extend along predetermined trajectories relative to each other.

Abstract: The needle-sized surgical tools used in arthroscopy, otolaryngology, and other surgical fields could become even more valuable to surgeons if endowed with the ability to navigate around sharp corners to manipulate or visualize tissue. A needle-sized bendable joint design that grants this ability. It can be easily interfaced with manual tools or concentric tube robots and is straightforward and inexpensive to manufacture. The bendable joint includes of a nitinol tube with several asymmetric cutouts, actuated by a tendon.

Abstract: A magnetic manipulation device (16) can include a housing (20), a spherical magnetic body (22) contained within the housing (20), and a plurality of sensors to detect the direction of the magnetic dipole of the spherical magnetic body (22). The spherical magnetic body (22) can be rotatable about a sphere axis of rotation which is (24a, 24b, 24c) can be in contact with the spherical magnetic body (22) to rotate the spherical magnetic body (22) about the sphere axis of rotation.

Abstract: A method of manipulating an untethered magnetic device, such as a magnetic capsule endoscope, can include positioning a magnet actuator and an untethered magnetic device proximate one another such that the untethered magnetic device is within a constant magnetic field of the magnet actuator. A position of the untethered magnetic device can be determined relative to the magnet actuator. A desired heading, position, and/or velocity of the untethered magnetic device can be identified. The method can include calculating a magnetic field heading and/or a magnetic force to be applied to the untethered magnetic device to achieve the desired device heading, position, and/or velocity. The magnetic actuator can be moved to apply the calculated magnetic field heading and/or magnetic force to the untethered magnetic device via the magnetic field.

Abstract: Systems and methods utilize a rotating magnetic field to drive a magnetically actuated device where the source of the rotating magnetic field is not constrained to a particular orientation with respect to the device. In one embodiment a rotating permanent magnet is utilized to actuate a magnetically actuated device where the magnet is not constrained to any position relative to the magnetically actuated device, such as the radial or axial position. Accordingly, the rotating permanent magnet may be directed in a manner to avoid collisions or other obstacles in a workspace while still effectively driving the magnetically actuated device.

Abstract: Wireless control of a microrobot can be performed using a magnetic field originating from a localized control magnet source relative to a body into which the microrobot is placed. Torque forces which contribute to rotation (and propulsion) of the microrobot can overcome magnetic forces which produce attraction or repulsion between the microrobot and the control magnet.
