Patent number: 9949753Abstract: Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting device is configured to engage patient formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting device is caused to move further into the engaged tissue and slit the tissue past the point of engagement.

Patent number: 9949762Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.Type: GrantFiled: October 11, 2016Date of Patent: April 24, 2018Assignee: Stryker European Holdings I, LLCInventors: T.

Patent number: 9949797Abstract: A method of implanting a hip joint prosthesis into a patient can include obtaining image data of hip joint anatomy of the patient. Physical activities that the patient desires to participate in subsequent to implanting the hip prosthesis can be determined. A size and an initial placement of the hip joint prosthesis based on the image data can be determined. A desired range of motion of the hip joint prosthesis based on the determined physical activities can be determined. A plan can be created comprising a desired implanted location of the hip joint prosthesis and based on the desired range of motion. The plan can be incorporated onto a guide. The plan can be executed with the guide thereby implanting the hip joint prosthesis into the patient at the desired implanted position.Type: GrantFiled: December 28, 2015Date of Patent: April 24, 2018Assignee: Biomet Manufacturing, LLCInventors: Jason D. Meridew, William Jason Slone, Mark Scrafton, John White, Seth Nash

Patent number: 9949799Abstract: Methods, apparatus, and systems for performing minimally invasive surgery through an aperture of a patient. In accordance with a method, parameters are received from an input device associated with a surgeon, the parameters indicating a desired state of an end effector of a surgical instrument oriented through the aperture. The surgical instrument is included in a mechanical assembly having a first set of joints. Instructions are then computed for controlling the mechanical assembly using the received parameters by computing instructions for controlling a second set joints, the second set of joints including the first set of joints and an additional joint, the additional joint being absent from the mechanical assembly. The mechanical assembly is then driven so as to move the end effector toward the desired state based on the computed instructions.Type: GrantFiled: February 29, 2016Date of Patent: April 24, 2018Assignee: Intuitive Surgical Operations, Inc.Inventors: Pushkar Hingwe, Samuel Kwok Wai Au, Raymond A. Bonneau, Nicola Diolaiti, Arjang M. Hourtash, Amy E. Kerdok, Michael Turner

Patent number: 9949800Abstract: A robotic surgical system is configured with rigid, curved cannulas that extend through the same opening into a patient's body. Surgical instruments with passively flexible shafts extend through the curved cannulas. The cannulas are oriented to direct the instruments towards a surgical site. A teleoperation control system that moves the curved cannulas and their associated instruments in a manner that allows a surgeon to experience intuitive control is disclosed. The flexible shaft instruments are controlled as if extending along a virtual straight line insertion and withdrawal axis. Various port features that support the curved cannulas within the single opening are disclosed. Cannula support fixtures that support the cannulas during insertion into the single opening and mounting to robotic manipulators are disclosed.Type: GrantFiled: February 16, 2016Date of Patent: April 24, 2018Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Giuseppe Maria Prisco, Samuel Au

Patent number: 9949801Abstract: Devices, systems, and methods for reconfiguring a surgical manipulator by moving the manipulator within a null-space of a kinematic Jacobian of the manipulator arm. In one aspect, in response to receiving a reconfiguration command, the system drives a first set of joints and calculates velocities of the plurality of joints to be within a null-space. The joints are driven according to the reconfiguration command and the calculated movement so as to maintain a desired state of the end effector or a remote center about which an instrument shaft pivots. In another aspect, the joints are also driven according to a calculated end effector or remote center displacing velocities within a null-perpendicular-space of the Jacobian so as to effect the desired reconfiguration concurrently with a desired movement of the end effector or remote center.Type: GrantFiled: November 22, 2016Date of Patent: April 24, 2018Assignee: Intuitive Surgical Operations, Inc.Inventors: Arjang M. Hourtash, Paul W. Mohr, Pushkar Hingwe, Paul Millman, Bruce Michael Schena, Roman L. Devengenzo, Scott Luke

Patent number: 9949802Abstract: The present invention provides systems and methods for performing robotically-assisted surgical procedures on a patient. In particular, a three-component surgical system is provided that includes a non-sterile drive and control component, a sterilizable end effector or surgical tool and an intermediate connector component that includes mechanical elements for coupling the surgical tool with the drive and control component and for transferring motion and electrical signals therebetween. The drive and control component is shielded from the sterile surgical site, the surgical tool is sterilizable and disposable and the intermediate connector is sterilizable and reusable. In this manner, the intermediate connector can be sterilized after a surgical procedure without damaging the motors or electrical connections within the drive and control component of the robotic system.Type: GrantFiled: September 15, 2010Date of Patent: April 24, 2018Assignee: Intuitive Surgical Operations, Inc.Inventor: Thomas G.
