Abstract: In some embodiments there is provided a headgear assembly for a full-face under-nose respiratory mask comprising a strap assembly including a rear panel, a crown strap, a pair of opposing upper side straps, and a pair of opposing lower side straps. The assembly further comprises a flexible headgear connector element, wherein a free end of each of the upper straps is coupled to the headgear connector element, and wherein the headgear connector element is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. There is also provided a respiratory mask assembly comprising a mask frame and a cushion module, the mask frame comprising a breathing gas inlet configured to receive a supply of breathable gas and to deliver the breathable gas to the cushion module, the cushion module being configured to form a seal with a user's face.

Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user. The valve member is provided with a tapered bead that helps prevent the valve member from sticking in a given position. Also, a connector for connecting a respiratory tube to an elbow connector.

Abstract: An electrosurgical instrument, a guiding catheter and a method for inserting an applicator into body lumina along a direction of insertion. The electrosurgical instrument includes a guiding catheter for inserting an applicator into body lumina along a direction of insertion and a counter sleeve, wherein the counter sleeve and the guiding catheter are arranged axially displaceably in relation to one another, and the guiding catheter in a distal region has at least one radial suction opening and the electrosurgical instrument is designed to produce a negative pressure in the guiding catheter, and wherein, furthermore, a cutting element is arranged on the suction opening and/or a distal end of the counter sleeve.

Abstract: The invention relates to an electrosurgical instrument for introducing a guide sleeve into a bodily lumen, in particular into a vascular system of the human lung. The invention also relates to a method for the ablation of human body tissue using high frequency voltage. The invention further relates to a use of an electrosurgical instrument for introducing into a bodily lumen. The electrosurgical instrument, according to the invention, for introducing into a bodily lumen, comprises a first applicator having at least one first electrode, and a second applicator having at least one second electrode, wherein the first applicator and the second applicator are designed in such a way that they can be positioned independently of one another in the bodily lumen.
