  • Patent number: 10470815
    Abstract: In some embodiments, a plurality of transducers of a transducer-based device may be selected for activation. A first pair of subsets of the selected transducers may be identified for initial activation, each subset of the first pair being activated with a different phase angle range than the other. No transducer in one subset is sufficiently close to a transducer in the other subset to cause a confluence of ablated tissue regions therebetween. The first pair of subsets may be activated simultaneously or concurrently. Upon activation or a conclusion thereof of the pair of subsets of the selected transducers, one or more subsequent pairs of subsets of the selected transducers may be activated iteratively on a pair-by-pair basis, until all of the selected transducers have achieved desired activation results, according to some embodiments. Each subsequent pair may include the same or similar characteristics as the first pair.

  • Patent number: 10441340
    Abstract: A forceps includes an end effector assembly having first and second jaw members each defining a proximal portion, a distal portion, and an intermediate portion. The distal portions define tissue-treating surfaces and the intermediate portions are disposed in overlapping relation relative to one another. A shaft is configured to receive the proximal portions and includes a retention feature for operably retaining the first and second jaw members at the distal end of the shaft. A drive bar is disposed within the shaft and operably associated with the proximal portions such that translation of the drive bar through the shaft and relative to the end effector assembly moves the first and second jaw members between a spaced-apart position and an approximated position for grasping tissue between the tissue-treating surfaces thereof.

  • Patent number: 10413352
    Abstract: An end effector for an electrosurgical instrument includes a pair of opposing first and second jaw members (2), (3), movable between an open position in which the jaw members are disposed in a spaced relation relative to one another, and a closed position in which sealing surfaces of the jaw members cooperate to grasp tissue therebetween. A first sealing electrode (9) is located on the first jaw member (2), while a second sealing electrode (10) is located on the second jaw member (3). One or both of the sealing surfaces are provided with electrically conductive stop members (12), the one or more stop members maintaining a predetermined spacing between the first and second sealing electrodes when the jaw members are in their closed position. One or more insulating members (14), (17), (19) are present to prevent the conductive stop members from causing an electrical short between the first and second sealing electrodes when the jaw members are in their closed position.

  • Patent number: 10398490
    Abstract: An argon beam coagulation probe for a robotic surgery system having a body with an argon gas entry port and an argon gas exit port and a pedestal interconnected to the underside of body that includes a pair of opposing arcuate channels that positioned equidistantly about the body. As a result, the argon gas jet exit port will be aligned equidistantly between the two fingers of a robotic arm and the body will be aligned in the same direction as the yaw axis of the robotic arm, so that argon gas will be expelled in the same direction that the fingers are pointing. A surgeon manipulating the robotic arms from the master control can thus easily align the probe based on the positioning of the robotic fingers and will still have the entire range of pitch, yaw, and roll movement of the robotic system.

  • Patent number: 10398488
    Abstract: An epicardial device, system, and method for stabilizing the left atrial appendage during a left atrial appendage ligation/occlusion procedure. A cryoadhesion device including a stabilization element is positioned within the pericardial space proximate the left atrial appendage through subxiphoid access. Once the stabilization element is in contact with the left atrial appendage, the stabilization element is cooled to a temperature that is sufficient to cryoadhere the stabilization element to the left atrial appendage. In this way, the cryoadhesion device stabilizes the left atrial appendage in order to perform left atrial appendage ligation/occlusion with a secondary medical device.

An outer surface of the distal end, and an inner surface of the main body, extend longitudinally between the proximal and distal ends. The inner surface defines at least one lumen with an opening terminating at the terminal portion of the distal end. At least one excisor is disposed on the extension with the excisor laterally spaced from the outer surface of the annular main body. The excisor remains stationary with respect to the lumen during use of the excisor to excize the target portion of the native tissue.
