  • 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: 20190070731
    Abstract: A robotic device includes one or more joints to position an end effector in a plurality of degrees of freedom. A navigation system tracks an actual position of the end effector. One or more controllers identify a condition wherein the actual position of the end effector contacts a virtual constraint. An anticipated movement of the end effector is evaluated from the actual position to a home position of the end effector. The one or more controllers detect an anticipated collision between the end effector and the virtual constraint and compute a target position of the end effector that evades the anticipated collision. The target position is spaced from the actual position and also contacts the virtual constraint. The one or more joints are controlled to slide the end effector from the actual position to target position along the virtual constraint.

  • 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.

  • Patent number: 9937338
    Abstract: An electrode array assembly with a frame that is foldable or bendable on which electrodes are disposed. The frame includes laterally spaced apart bridges. Tabs extend laterally outwardly from the bridges Electrodes are disposed on the tabs. Beams, also part of the frame, extend between the laterally adjacent bridges. The frame can be folded around the beams so as to cause the laterally spaced bridges to at least partially overlap. When the beams are so bent, the electrode array can be disposed in an access cannula that has a diameter less than the width of the unfolded array.

  • Patent number: 9707043
    Abstract: An instrument for treating tissue during a medical procedure includes a hand-held portion and a working portion. The hand-held portion is manually supported and moved by a user and the working portion is movably coupled to the hand-held portion. A tracking device is attached to the hand-held portion for tracking the instrument. The tracking device is in communication with a control system, which is used to keep the working portion within or outside of a boundary. A plurality of actuators are operatively coupled to the working portion. The control system instructs the actuators to move the working portion relative to the hand-held portion during the medical procedure in order to maintain a desired relationship between the working portion and the boundary.

  • Patent number: 9345552
    Abstract: A method of performing a minimally invasive procedure on a hip joint of a patient to relieve a femoral acetabular impingement. An access device is placed through skin of the patient to provide minimally invasive access to a target volume of material that creates the femoral acetabular impingement. A cutting accessory is placed into the access device to remove material and relieve the femoral acetabular impingement. A tracking and control system establishes a virtual boundary that defines the target volume of material that creates the femoral acetabular impingement, tracks a position of the cutting accessory relative to the virtual boundary, and controls movement of the cutting accessory so that cutting is substantially maintained within the virtual boundary.
