  • Patent number: 9579145
    Abstract: An endoscopic forceps is disclosed including an end effector assembly having two jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween. Each of the jaw members is connectable to an electrosurgical energy source for conducting energy through tissue held therebetween. The jaw members are biased to the first position. The end effector assembly of the endoscopic forceps further includes a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the jaw members and operatively associated with the other of the jaw members. In use, withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to a second position and clamping of the tissue between the jaws.

  • Patent number: 8992460
    Abstract: To treat body surfaces, such as the sinuses, which are coated with biofilms, the surface is irrigated and suctioned with a fluid which may contain a biocide or other chemical agent for disrupting the biofilm while ultrasonic energy is applied to either the fluid barrier formed over the biofilm or a body surface proximal to the biofilm. Action of the fluid enhanced by the ultrasonic energy tends to remove sections of biofilm which are suctioned out of the site. An electrical field may also be applied to the biofilm to enhance the disruptive action. Apparatus for practicing this method to treat chronic rhinosinusitis comprises an elongated tube adapted to be inserted into sinus cavities through the nose or mouth. The tube includes a first lumen which feeds an irrigating fluid containing biocides and/or biofilm-disruptive chemicals to the treatment site and a second lumen which suctions fluid from the site.

    Abstract: Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redirecting inspired air to other healthier lung areas. Trans-tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated, patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. Typically the catheter's distal tip is anchored without occluding the bronchus. TTSV is optionally performed by insufflation only of the area, or by the application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.

  • Patent number: 8864709
    Abstract: In a medical liquid supply device, a control unit controls a liquid supply driver so that a liquid flows from the liquid supply driver in a liquid supply path regardless of whether a liquid-supply ON mode is selected. All of the liquid flowing from the liquid supply driver flows into a communication path when the liquid-supply ON mode is not selected. At least a part of the liquid flowing from the liquid supply driver does not flow into the communication path and is thereby supplied from a distal end of the liquid supply path when the liquid-supply ON mode is selected.

  • Patent number: 8858534
    Abstract: A vacuum system for draining an open wound from liquids exuded therefrom, comprising an enclosure sealable to the wound circumference, a vacuum pump including a disposable pump unit detachably attachable to a non-disposable drive unit, and a waste container for collection of drained liquids. The enclosure has an outlet connected by means of a tube to an inlet of the pump unit and the waste container is connected to an outlet of the pump unit, such that when the vacuum pump is operated the drained liquids flow through the vacuum pump. The enclosure has one or more bleeding holes provided therethrough or adjacent to its outlet so that ambient air may enter the tube and flow together with the drained liquids. The enclosure and the waste container are disposable so that the drained liquids contact only disposable elements and may be disposed of together with all disposable elements.

  • Patent number: 8852139
    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

  • Patent number: 8845576
    Abstract: An electrosurgical tool for cauterizing or ablating patient tissue, which tool includes a tubular shaft which defines therein a conduit in communication with a suction source and which mounts an electrode at the distal end thereof. An electrode support element is provided at the distal end of the shaft for mounting and insulating the electrode. The support element and the electrode together define a suction opening at the treating surface of the electrode which minimizes clogging of the tool.

    Abstract: A nasogastric/orogastric (Ng/Og) device includes a main lumen configured for at least one of gastric decompression, enteral feeding and enteral medication administration. An expandable esophageal cuff is carried by the device body and configured in a normally expanded position such that when inserted within the esophagus, the esophageal cuff conforms to the interior surface of the esophagus and emesis and/or reflux is blocked from passing out of the stomach and past the esophageal cuff. A vacuum lumen is carried by the device body and connected to the expandable esophageal cuff. When vacuum is applied, the esophageal cuff is contracted against the device body to permit the device to be inserted and placed within the esophagus. When the vacuum is released, the esophageal cuff expands against the interior surface of the esophagus.

  • Patent number: 8808287
    Abstract: An electrosurgical suction coagulator is disclosed having improved thermal insulation between the active electrode and adjacent tissue. In embodiments, passive insulation is used to control the transfer of thermal energy from an electrosurgical electrode into surrounding tissue. Braided, closed-sell foam material, and open cell foam materials may be used to thermally insulate the outer surface of a suction coagulator shaft from an inner electrode. In embodiments, a suction coagulator shaft includes an external covering formed from open-cell foam material, which may be saturated with a coolant, such as water or saline, to increase the thermal mass of the shaft. In other embodiments, active cooling delivers coolant to the operative site. In yet other embodiments, a suction coagulator shaft includes a cooling jacket through which coolant is passed to actively cool the instrument.
