The invention is a transgastric method for the endoscopic partial fundoplication for the treatment of gastroesophageal reflux disease (GERD). The method makes use of an articulated endoscope, which is introduced through the mouth and esophagus into the stomach of the patient. A cutting tool is introduced through the working channel of the endoscope to cut a hole in the wall of the stomach. The endoscope is pushed through the hole and a grabbing tool is introduced through the working channel and used to grab the tissue at a location on the outer surface of the stomach and move the grabbed tissue close to the esophagus. The grabbed tissue is then stapled to the esophagus using a stapling device that is an integral part of the endoscope. If desired, after stapling the endoscope can be rotated one or more times and the procedure repeated. After the selected portions of the stomach wall have been attached to the esophagus, the endoscope is withdrawn from the body of the patient and the hole in the stomach wall is closed, preferably by means of a dedicated endoscopic stapling device especially designed for the task of closing holes in tissue.

Apparatus for the application of topical negative pressure therapy to a wound site is described, the apparatus comprising: a wound contacting element for retaining wound exudate fluid therein; a wound covering element that provides a substantially airtight seal over the wound contacting element and wound site; a vacuum connection tube connecting a wound cavity to a vacuum source; and a vacuum source connected to a distal end of the vacuum connection tube.

A pharyngeal retractor device and implantation methods are provided for use in the treatment of obstructive sleep apnea. The device includes a retracting element and a tissue engaging element that promotes tissue ingrowth around or onto the retracting element. The device is implanted in tissue space beneath the pharyngeal wall to alter the shape of the wall. The device may be implanted through the oral cavity alone or by using a trocar or a hand-held delivery system to deliver the device through the pharyngeal wall. Alternatively, the device may be implanted using an open, direct visualization approach from the side of a patient's neck.

A smoking device for generating and releasing smoking vapor free from contamination into the mouth of a user comprising a mouthpiece for providing vapor for inhalation to a user including a tubular casing containing a heater for heating a smoking substance at a substantially constant low temperature by regulating the flow of fuel by a thermal regulator and further having means for visual indication of the operation of the device.

The invention provides a method and system for ablation of body structures or tissue in a sphincter, sinus or orifice such as the rectum, colon, esophagus, vagina, penis, larynx or pharynx. In one aspect of the invention, the environment surrounding the targeted ablation region can be isolated or controlled by blocking the flow of gases or liquids using an inflatable balloon positioned immediately adjacent to the tissue that is to be ablated. In a preferred embodiment, the inflatable balloon also serves to anchor the catheter in place and prevent the catheter from being expelled from the body. The inflatable balloon also insures that locally administered drug remain in the area where most needed. In a second aspect of the invention, positive pressure is used to inflate the balloon. Inflation of balloon triggers the extension of at least one curvilinear electrode into the targeted tissue. Negative pressure deflates the air sac and helps retract the curvilinear electrodes so as to allow the catheter to be removed from the body without damaging adjacent body structures. In a third aspect of the invention, the electrodes are coupled to sensors that measure properties of the target region such as temperature and impedance. Measurement of these properties permits the use of feedback technique to control delivery of the RF energy and administration of fluids for cooling and hydrating the affected tissues. In a fourth aspect of the invention, the catheter includes an optical path that can be coupled to external viewing apparatus. In this way, the position of the electrodes in the body can be determined by fluoroscopic or fiber optic techniques.

A breathing arrangement includes a patient interface, at least one inlet conduit, and a headgear assembly. The patient interface includes a mouth covering assembly including a cushion structured to sealingly engage around exterior of a patient's mouth in use, a nozzle assembly including a pair of nozzles structured to sealingly engage within nasal passages of a patient's nose in use, and a flexible element connecting the mouth covering assembly and the nozzle assembly. The at least one inlet conduit is structured to deliver breathable gas into at least one of the mouth covering assembly and the nozzle assembly for breathing by the patient. The headgear assembly is removably connected to at least one of the mouth covering assembly and the nozzle assembly so as to maintain the mouth covering assembly and the nozzle assembly in a desired position on the patient's face.
