  • Patent number: 10201384
    Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

  • Patent number: 10111699
    Abstract: A variety of surgical instruments include one or more elements that transmit RF energy to tissue. Some such instruments comprise a pair of jaws that open and close on tissue, with conductive tissue contact surfaces that are operable to weld tissue clamped between the jaws. Some surgical instruments also include a translating tissue cutting element. Some such instruments may be in the form of forceps having a scissor grip. When an electrosurgical instrument includes grasping jaws and tissue severing capabilities it may be desirable to avoid accidental cutting by the knife. Hence, the instrument may include a feature that prevents the knife from firing until the jaws are sufficiently closed upon the tissue. It may also be desirable to prevent the jaws from being opened until the knife has been retracted. One or both of these features can prevent the knife from being extended while the jaws are open.

Some surgical instruments also include a translating tissue cutting element. Some such instruments may be in the form of forceps having a scissor grip. Forceps type instruments may in some instances provide a feature that allows the jaws of the forceps to be locked on tissue, so that the operator can remove his or her hands from the instrument. In such an instrument it may also be desirable to provide a circuit that is activated only when the forceps are closed and sufficient pressure is applied to the tissue between the jaws of the device.

  • Patent number: 10052125
    Abstract: Described herein are atherectomy catheters, systems and methods that include a distal tip region that may be moved laterally so that its long axis is parallel with the long axis of the main catheter body axis. Displacing the distal tip region laterally out of the main catheter body axis exposes an annular blade and opens a passageway for cut tissue to enter a storage region within the catheter. The annular blade may be internally coupled to a drive shaft that rotates the blade, and thus the exposed blade edge may have the same crossing profile (OD) as the rest of the distal end region of the catheter. Also described herein are gear-driven atherectomy devices that may use a cable drive shaft to actuate the annular blade. Both push-to-cut and pull-to-cut variations are described, as are methods for cutting tissue and systems including these atherectomy catheters.

  • Patent number: 10045809
    Abstract: A vessel dissector for harvesting a target vessel from a donor has a generally cylindrical tip body with a sloping channel formed along a longitudinal side. A channel bottom provides a channel depth that decreases from a distal channel end to a proximal channel end. The tip body has a crescent-shaped forward lip extending distally from the channel. An arcuate collar is slidably disposed in an arcuate recess within the tip body to selectably bridge the channel at the distal end of the channel to form a ring profile with the forward lip. A first ferromagnetic heating element is disposed along a radially outward surface of the forward lip. A second ferromagnetic heating element is disposed on a distal edge of the arcuate collar. The first and second ferromagnetic heating elements are adapted to be energized simultaneously to make a vasiform cut including a pedicle around the target vessel.
