    Abstract: An electrosurgical device having an electrode with a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. An elongated hollow body has an internal cavity, a front end, a rear end, an external surface. An electrical circuit is arranged within the body. The second portion of the electrode is not surrounded by the hollow body. A first button is arranged on the external surface of the body for controlling a current flow at a first level. A vacuum tube is slidably engaged by the body. The vacuum tube is configured with a blade holder to reversibly receive the third portion of the electrode such that electrical contact is made between the electrode and a conductor which is connected to the electrical circuit by electrical connector. A vacuum outlet port is arranged near the rear end, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

  • Patent number: 8999074
    Abstract: A cleaning catheter (200) includes fluid-delivery and suction lumens (520, 530). A flow regulator (700) defines suction and fluid ports (830, 827). A mechanical user control element (320) is configured to mechanically and non-electrically set activation states of the flow regulator (700), and transition between first and third configurations via a second configuration. When the control element (320) is in the first configuration, the flow regulator (700) blocks fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the second configuration, the flow regulator effects fluid communication between the suction port (830) and the suction lumen (530), and blocks fluid communication between the fluid port (827) and the fluid-delivery lumen (520).

  • 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.

  • Patent number: 8955518
    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.

    Abstract: The illustrative embodiments described herein are directed to systems, methods, and apparatuses for applying a reduced pressure to a subcutaneous tissue site. In one instance, a manifold for applying reduced pressure to a subcutaneous tissue site includes a plurality of first conduits, each of the plurality of first conduits having a wall with at least one first aperture and at least one second aperture. At least one of the plurality of first conduits is operable to deliver reduced pressure to the subcutaneous tissue site. The plurality of first conduits is coupled in a spaced arrangement that forms an interior space. The manifold further includes a second conduit comprising the interior space and formed by a portion of each wall of the plurality of first conduits. The second conduit is in fluid communication with the plurality of first conduits via the at least one second aperture.

  • Patent number: 8939927
    Abstract: An assembly for a phacoemulsification surgical system includes an aspiration system arranged to aspirate fluid from a surgical site. The aspiration system includes an aspiration path within the phacoemulsification hand piece and includes a flexible small bore aspiration tubing in fluid communication with the aspiration path. The small bore aspiration tubing has a nominal inner diameter smaller than about 0.050 inch to reduce levels of occlusion surge within the surgical system. A high-output, peristaltic pump communicates with the small bore aspiration tubing and is operable to create a flow through the small bore aspiration tubing.

    Abstract: A surgical handpiece has a connecting body with a distal end and a work tip with a hub at a proximal end. The hub is detachably connected to the connecting body by a threaded connector. The work tip has an open operating end at a distal end. This opening leads an axial channel extending through the work tip from the operating end to the hub. A radial channel extends from the axial channel in the hub to the external surface of the hub. A sleeve surrounds and is spaced from the hub. This sleeve extends to the vicinity of the operating end of the work tip, and has a first external connector in the region of the radial channel of the hub. The sleeve also has a second external connector. A seal is provided for establishing a fluid connection between the radial channel of the hub and the second external connector of the sleeve. The first external connector of the sleeve is in fluid connection with an irrigation channel between the inner surface of the sleeve and the external surface of the work tip.
