  • Patent number: 10806535
    Abstract: 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.

  • Publication number: 20200323656
    Abstract: A prosthetic knee (10) for a transfemoral amputee has a monocentric rotational joint (20) that rotatably attaches an upper housing (12) attachable to the amputee's residual limb to a lower housing (16) attachable to a below-the knee prosthesis. A locking mechanism (32) disposed in the lower housing (16) has a piston (34) biased in a locked position releasably engaging the upper housing (12) preventing rotation of the rotational joint (20). An unlocking mechanism (32) having a trigger (48) attached to a posterior side of the lower housing (16) by a pair of spaced-apart trigger links (52) is configured to unlock the locking mechanism (32). A piston rod (62) having a first piston-rod end (64) pivotably attached to one of the trigger links (52) has a second piston-rod end (68) pivotably attached to the piston (34).

  • 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.

  • Publication number: 20160228032
    Abstract: A system and method of tracking a flexible elongate instrument within a patient is disclosed herein. The system is configured to obtain remote localization measurement data of the flexible elongate instrument and obtain elongation measurement data of the flexible elongate instrument. This data is combined and transformed to a coordinate reference frame to produce a localization of the flexible elongate instrument that is more accurate than the remote localization measurements or elongation measurement data alone. The combined localization is then provided to a localization consumer.
