  • Patent number: 11890134
    Abstract: A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

  • Patent number: 11547287
    Abstract: A tool comprises a distal portion and a proximal portion spaced apart by a shaft along a longitudinal axis. The distal portion includes a distal link and the proximal portion including a proximal link. The distal link and proximal link form a pair of links. The tool also comprises a set of tension load bearing members connecting the proximal link and the distal link and terminating at the links of the pair to transfer movement therebetween. The tool also comprises an articulation lock positioned between the distal portion and the proximal portion and configured to allow through passage of the set of tension load bearing members. The articulation lock is adjustable between an unlocked configuration in which the proximal and distal links are moveable and a locked configuration in which an effective length of the shaft is increased, creating a force to impede movement of the proximal and distal links.

  • Patent number: 11491310
    Abstract: A surgical tool comprises a pair of opposing jaws moveable relative to each other between a closed position and first and second open positions. The opposing jaws remain substantially parallel to one another when moving between the closed position and the first open position and remain non-parallel to one another when moving between the first open position and the second open position.

  • Patent number: 11439394
    Abstract: The present invention relates to surgical clamps and clamp devices that provide a handle-free surgical field and to methods of operating such clamps and clamp devices. Such methods may include moving a second rotating element relative to a first rotating element such that the rotational axis of the second rotating element is not parallel to the rotational axis of the first rotating element and rotating the first rotating element about the rotational axis of the first rotating element to cause rotation of the second rotating element about the rotational axis of the second rotating element. The rotation of the second rotating element causes translation of a first actuation element along the rotational axis of the second rotating element. The translation of the first actuation element causes pivotal motion of the first jaw portion towards the second jaw portion. Other methods and devices are provided.

  • Publication number: 20220134087
    Abstract: A handheld, therapeutic electrode and connector that are compatible with high voltages from a pulse generator are disclosed. The electrode includes therapeutic terminals on a tip configured to deliver high voltage pulses safely to a patient. The electrode includes sleeves, bosses, wiring channels, and other features that maximize a minimum clearance distance (across non-conductive surfaces) and air clearance between conductive connectors themselves or the connectors and a user, thus preventing dangerous arcing. Internal surfaces and seams are taken into account. The connector and its mating outlet can include similar features to maximize clearance distance. Skirts, skirt holes, and finger stops are also employed, and they can be on either the connector or outlet, or the tip or handle of the electrode.
