  • Publication number: 20170281211
    Abstract: Various surgical devices are provided having mechanisms for preventing premature actuation of a cutting mechanism. These devices generally include a handle having one or more actuators and an effector disposed at a distal end of the device and configured to grasp tissue. When the end effector is in an open position, a firing actuator can be positioned so that it cannot be actuated by a user. For example, the firing actuator can be obstructed by a shield or arm when the end effector is in the open position. In other embodiments, the firing actuator can be hidden in a recess formed in the closure actuator until the end effector is moved to the closed position. When the end effector is in the closed position, the firing actuator can be engaged to advance a cutting mechanism, thereby cutting the tissue grasped by the end effector.

  • Publication number: 20170247027
    Abstract: A vehicle comprises a hybrid powertrain includes an electric machine coupled between an automatic gearbox and an engine. The vehicle includes paddle shifters configured to output a driver requested gear change. The hybrid powertrain is configured to selectively operate in an economy mode that optimizes fuel economy. While operating in the economy mode, a controller may selectively inhibit the driver requested gear change when the change may negatively impact fuel economy. In the economy mode, the driver requested gear change may be inhibited during a demand for braking. If the driver requested gear change is a downshift request, the downshift is inhibited and simulated using electric machine torque.

  • Publication number: 20170238991
    Abstract: The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

  • Patent number: 9737355
    Abstract: Various embodiments are directed to electrosurgical systems for providing an electrosurgical signal to a patient. A control circuit may, for a first application period, apply the electrosurgical signal to first and second electrodes according to a first mode. In the first mode, the control circuit may limit the electrosurgical signal to a first maximum power when the impedance between the first and second electrodes exceeds a first mode threshold. The control circuit may also, for a second application period after the first application period, apply the electrosurgical signal according to a second mode. In the second mode, the control circuit may limit the electrosurgical signal to a second mode maximum power when the impedance between the first and second electrodes exceeds a second mode threshold. The second maximum power may be greater than the first maximum power.

  • Patent number: 9707029
    Abstract: Various surgical devices are provided for shielding tissue from potentially harmful byproducts generated by surgical devices that use energy to treat tissue. In general, a shield member is provided that includes a connector element for removably connecting the shield member to a surgical device and a shield body configured to extend adjacent to an energy-emitting end effector of the device. When energy is delivered to treated tissue captured by the end effector, the shield body can be configured to serve as a physical barrier between the end effector and tissue adjacent to the treated tissue. In this way, the shield member can protect the adjacent tissue from potentially harmful byproducts of the end effector, e.g., heat and steam, and/or can deflect the byproducts back toward the treated tissue.

  • Patent number: 9700333
    Abstract: Surgical instruments and methods for applying variable compression to tissue are described herein and can have particular utility when cutting and sealing tissue. In one embodiment, a surgical instrument end effector is described that includes first and second jaw members movable relative to one another between an open position and a closed position to clamp tissue therebetween. The end effector can include a compression member configured to translate along the end effector to move the first and second jaw members and apply a variable compression force to the tissue. The variable compression force can have different profiles along the length of the end effector, including, for example, a continuously increasing profile or a profile that alternates between different values. The provided variable compression can reduce the force required to actuate the surgical instrument and increase the quality of a tissue seal formed thereby.

  • Patent number: 9675405
    Abstract: Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device can include at least one sensor and a motor, and an output of the motor can be configured to be adjusted based at least in part on an output from the at least one sensor. The output of the motor can be configured to provide power for translation of a cutting element along an end effector of the device. Adjusting the motor's output can cause the cutting element to translate through the end effector at different speeds, thereby allowing the cutting element to cut through tissue being grasped by the end effector at different speeds.

  • Patent number: 9505405
    Abstract: Data is collected from vehicle sensors to generate a virtual map of objects proximate to the vehicle. Based on the virtual map, an in-vehicle computer determines a traffic condition in front of and behind a host vehicle. The in-vehicle computer determines collision avoidance maneuvers. The computer instructs vehicle control units to implement the collision avoidance maneuvers. The computer may additionally or alternatively communicate the collision avoidance maneuvers to a driver via an interface. In the case of unavoidable collisions, the computer determines and initiates damage mitigation actions.
