  • Patent number: 9439716
    Abstract: An electrosurgical device that can be used to remove pedunculated tissue structures such as polyps and certain uterine fibroids includes bipolar surface electrodes and a bipolar snare. The device includes a probe having a proximal end and a distal end, bipolar surface electrodes adjacent to the distal end of the probe, and a bipolar snare extending distally from the distal end of the probe and including first and second snare electrodes. The bipolar surface electrodes are separated from each other by a gap and extend over a portion of the distal end of the probe. Providing both a bipolar snare and bipolar surface electrodes advantageously reduces thermal spread from occurring (compared to the use of a monopolar snare) when using the snare to excise the tissue. The bipolar surface electrodes can be used to coagulate the point of excision.

  • Patent number: 9089337
    Abstract: An electrosurgical system includes a grasper and a snare that each includes electrodes. The grasper includes a first electrode that is attachable to a first output of an energy supply. The snare includes a second electrode that is attachable to a second output of the energy supply. When the first and second electrodes are coupled to the energy supply, the grasper and snare operate as a bipolar electrosurgical system. By grasping the tissue with the jaws of the grasper, the current path between the electrode on the snare and the electrode on the grasper is relatively short, and thus the system operates like a bipolar electrosurgical system. Accordingly, the applied energy can be focused to a small area, minimizing damage to surrounding tissue. In addition, energy suitable for coagulating the cut portion of the stalk of the removed tissue can be readily applied with the bipolar electrosurgical system.

  • Publication number: 20140378963
    Abstract: Methods and apparatus for ablating blood vessels in treatment of uterine fibroids. A monopolar electrode provided on a needle probe is positioned in an artery supplying blood to a uterine fibroid. Energy is supplied to the electrode to ablate the artery. In this way, the uterine fibroid and the surrounding tissues remain relatively undamaged, and the uterine fibroid, deprived of its blood source, is allowed to necrose and eventually shrink.

  • Patent number: 8435261
    Abstract: Devices, methods and kits which, when installed or used, access, aspire, dilate, insufflate, drain or deliver fluid medicaments to, or place a patency device within a sinus area, such as a maxillary sinus or a maxillary sinus ostium. The device can include a hollow catheter and probe, and can be configured to permit gradual and incremental probe extension. The device can be constructed to enhance the precision and maneuverability within the nasal and sinus passageways, while also accommodating the natural anatomical geometry of a targeted paranasal treatment site. For example, the present treatment and placement device can accomplish access to the maxillary sinus ostium by utilizing an uncinate process to guide a probe tip into the ostium in a retrograde manner. The probe can be slidably, bi-directionally or co-axially positioned within the catheter. A distal portion of the probe can be biased away from a longitudinal axis of the catheter.

  • Publication number: 20110015612
    Abstract: Devices, methods and kits which, when installed or used, urge or maintain patency of sinus ostia, such as the ostium between a nasal passageway and a maxillary sinus, while maintaining some function of cilia extending within or near the ostium. In various examples, the devices comprise a first portion, a second medial portion including a partially open cross-sectional configuration, and a third portion including one or more flexible and outwardly-biased projections. The partially open cross-sectional configuration can maintain a track of uncovered cilia within and near the ostium. In some examples, the devices can include an asymmetric body configuration. In some examples, the first portion includes a U-shaped configuration and the third portion includes at least two flexible and outwardly-biased projections. In some examples, the first, second or third portion includes a medication for delivery into sinus tissues.
