  • Patent number: 11684350
    Abstract: A lead delivery catheter having a slittable pull ring is described. The lead delivery catheter includes a deflection wire attached to the slittable pull ring to deflect the catheter. The slittable pull ring has several ring holes arranged in a pattern. The pull ring is located distal to a tubular braid of the lead delivery catheter, and a size and pattern of the ring holes can be similar to a size and pattern of holes in the tubular braid. The structural similarity between the pull ring and the tubular braid facilitates use of a consistent cutting force to slit through the tubular braid and the pull ring of the lead delivery catheter. Other embodiments are also described and claimed.

  • Patent number: 11627959
    Abstract: A surgical instrument comprising an end effector, an articulation system, a firing system, a closure system, a lock system, and a control unit is disclosed. The end effector comprises a pair of movable jaws. The articulation system articulates the end effector when the articulation system is in an active state. The closure system is actuatable to move the pair of jaws. The lock system prevents the closure system from actuating when the lock system is in a locked state. The control unit controls the supply of power from a power source to the articulation system, the firing system, and the lock system. The control unit transitions the lock system to the locked state and prevents the supply of power from the power source to the firing system when the articulation system is in the active state.

  • Patent number: 11596770
    Abstract: Systems and method for controlling the bending of a robotic catheter. A control backbone of the robotic catheter is coupled to a linear movement stage by a spring and linear movement of the control backbone causes a controllable bending of the robotic catheter. A sensor monitors a deflection of the spring and the bending of the catheter is controlled based on the spring deflection signal from the sensor. The spring allows passive bending of the robotic catheter without movement of the active linear movement stage and, conversely, allows external forces applied to the robotic catheter to limit a bending movement of the robotic catheter caused by—movement of the active linear movement stage. In some implementations, the robotic catheter includes a selectively deployable tip mechanism for deploying a steerable tip or for selectively exposing side windows on the catheter for increasing traction for clot removal.

  • Patent number: 11002346
    Abstract: A hand held, hand operated apparatus for rotating, or spinning, rotatably oscillating and/or inducing back and forth longitudinal movement in a device, such as an elongated medical device. A drive shaft of the hand held, hand operated rotational drive apparatus includes a ratcheting mechanism capable of enabling oscillating (repeated forward and reverse) rotation of a device that has been coupled thereto when there is little or no resistance on the rotated device, and of enabling an actuator to return to a position that will enable further forward, or driving, rotation of the drive shaft and the rotated device when resistance on the rotated device prevents the rotated device and the drive shaft from rotating in a reverse direction.

    Abstract: A handle assembly is provided for use in navigating a deformable shaft within a body. The assembly includes a first guide member defining first and second linear channels and a second guide member configured for rotation relative to the first guide member. First and second connectors are disposed within, and movable within, the first and second linear channels along first and second parallel axes, respectively, and are configured for coupling to first and second steering wires, respectively. The assembly includes means, such as a flexible coupling connected to the second guide member and the connectors, for translating rotation of the second guide member into linear movement of the first connector in a first axial direction and linear movement of the second connector in a second axial direction, opposite the first axial direction such that the first and second steering wires move in opposite directions.

  • Patent number: 10967151
    Abstract: A steerable catheter comprises a mobile tube and an intermediate tube, coaxial with each other, which extend from a proximal end to a distal end of the catheter and are telescopically mounted into each other with possibility of mutual rotation and axial translation. The mobile tube comprises a central lumen extending from the proximal end to the distal end. The intermediate tube comprises, along its whole length, a longitudinal notch radially offset in a direction of offset with respect to the axis of the steerable catheter and extending axially from the proximal end to the distal end. The longitudinal notch contains a cable adapted to undergo a traction exerted from the proximal end, the traction generating a bending of the steerable catheter directed towards the offset direction. The steerable catheter further comprises around the intermediate tube a sealed external sheath surrounding the intermediate tube over its periphery and covering the longitudinal notch over its length.

  • Patent number: 10945757
    Abstract: A method of two-phase atherectomy for removal of plaque within an artery forming a stenosis including a first phase of rotational drilling by exerting a rotational force on a cutter to form a channel within the plaque having a diameter substantially equal to a diameter of the cutter—the cutter being rotated at a first rotational speed sufficient to maintain rotation of the cutter about a stationary rotational axis—and a second phase of orbital impact by exerting a rotational force on the cutter to result in radial orbital motion of the cutter within the channel resulting in periodic impact of the cutter upon the plaque to form micro-fractures within the plaque and enlarge the diameter of the channel to a diameter substantially greater than the diameter of the cutter—the cutter being rotated at a second rotational speed to result in the radial orbital motion of the cutter.

    Abstract: A fluoroscopic surgical system employing a FORS sensor (40), a navigation controller (70), a fluoroscopic imager (30) and a mechanical connector (50) adjoined to the fluoroscopic imager (30). In operation, mechanical connector (50) is utilized to detachably attach FORS senor to fluoroscopic imager (30), whereby navigation controller (70) processes a shape reconstruction of FORS sensor (40) relative to a reference point fixed or movable within an operating space (20) for controlling a tracking of fluoroscopic imager (30) within the operating space (20). The system may further employ a surgical instrument (60) whereby, concurrently or subsequently to a fluoroscopic imaging of a patient anatomy, FORS sensor (40) is thereafter detached from fluoroscopic imager (30) and detachably attached to surgical instrument (60), or FORS sensor (40) is concurrently detachably attached to fluoroscopic imager (30) and surgical instrument (60).

  • Patent number: 10773383
    Abstract: A method and a system stream robot tool center point position to external processors at high frequency. The method includes the steps of: reading robot joint encoder data using an Interrupt Service Routine in the robot controller; calculating tool center point position based on the encoder data; and sending the calculated position data to a network socket in a high priority task. The method achieves tool center point and/or joint position communication at fast and consistent time intervals, as compared to much longer times for prior art methods. A downstream device, such as a processor or controller for another machine, reads the communicated tool center point and/or joint position data and uses it to control the operations of its own device. High speed motion command streaming from outside processors can be used in a similar way to control the robot.
