  • Patent number: 11648679
    Abstract: A robotic device includes one or more actuators to position an end effector in a plurality of degrees of freedom. A navigation system tracks an actual position of the end effector. A controller identifies a condition wherein the actual position of the end effector contacts a virtual constraint. The controller determines that an anticipated movement of the end effector from an actual position to the home position would cause a collision between the end effector and a virtual constraint and computes a target position of the end effector that avoids the collision. The target position is spaced from the actual position and computed with respect to the virtual constraint. The one or more actuators are controlled to move the end effector from the actual position to target position along the virtual constraint.

  • Patent number: 10842533
    Abstract: An electrode array and a delivery assembly are disclosed. The array is wrapped around a flexible core part of the delivery assembly. A sheath, also part of the delivery assembly, is disposed over the array and core. Steering cables extend through the core. Once the delivery assembly-encased array is inserted in the body, the combination is advanced to the tissue over which the array is to be deployed. By pulling on the steering cables the array and assembly are steered into position. Once the array is in position, the sheath is retracted, the array deploys over the target tissue.

  • Patent number: 10813697
    Abstract: Methods of removing tissue from a patient during a surgical procedure, such as for preparing a spine of a patient to receive an implant during a fusion procedure. A working portion of an instrument is moved with actuators relative to a hand-held portion in at least three degrees of freedom including pivoting in pitch and yaw about a pivot. The working portion is translated while the hand-held portion is manually grasped and moved during the surgical procedure. The working portion is rotated with a drive mechanism to remove a volume of the tissue of the patient with a cutting accessory of the working portion. The actuators may move the working portion to substantially maintain the cutting accessory in a desired relationship to a virtual boundary defining the volume of the tissue to be removed. A position of the cutting accessory relative to the virtual boundary may be determined and tracked.

  • Publication number: 20180185632
    Abstract: An electrode array and deployment assembly includes an access cannula comprising an outer structural member formed from material insertable in living tissue and defining a lumen opening at a distal end. An electrode assembly has a frame and at least one electrode disposed on the frame. A deployment cannula has a lumen and a distal end opening. The deployment cannula is disposed in the lumen of the outer structural member and configured to be discharged from the lumen opening and rotated during discharge. The electrode assembly is disposed in the lumen of the deployment cannula for discharge from the distal end opening of the deployment cannula lumen. The electrode assembly is seated in the deployment cannula lumen in a select orientation and is configured to rotate with the deployment cannula so that the rotation of the deployment cannula results in a rotation of the electrode assembly.
