Abstract: Methods and apparatus to couple valve shafts and closure members are described. An example coupling apparatus includes an expansion pin to be disposed in a bore defined by a first aperture of a valve shaft and a second aperture of a closure member. The first and second apertures are coaxially aligned when the valve shaft is coupled to the closure member. A first tapered pin is disposed in a first opening of the expansion pin adjacent a first end of the expansion pin and a second tapered pin is disposed in a second opening of the expansion pin adjacent a second end of the expansion pin. The first tapered pin causes the expansion pin to expand at a first location when the first tapered pin is disposed in the first opening and the second tapered pin causes the expansion pin to expand at a second location different than the first location when the second tapered is disposed in the second opening.

Abstract: A device for the in situ clearing of blockages in a tube includes a controller and a clearing member. The controller can have a housing and an actuator for generating repetitive motion. The clearing member can be releasably coupled to the controller and suitable for insertion in the tube. The tube can be at least partially disposed within a living being. The controller can be located external to the living being. The clearing member can have a first end releasably coupled to the actuator, at least one flexible section which permits axial displacement of the clearing member, and a second end suitable for repetitively engaging and disrupting the blockage. The flexible section permits the clearing member to repetitively engage and disrupt the blockage within one of a straight and a curved portion of the artificial tube.

Abstract: A device and method for the removal and disposal of transected hair from the body of a patient in an operating room or other sterile location. The hand-held device is single-use, latex-free, sterile-packaged, non-conductive, fully disposable and comprises a hollow handle with a projecting wand ending in an enlarged distal tip. The other end of the hollow handle opposite the enlarged distal tip is connected to a vacuum source, such as the one readily available in most operating rooms, via flexible tubing. When the wand and the enlarged distal tip are passed over transected hair, the hair is suctioned into the hand-held device. The hand-held device includes a particulate filter to prevent the suctioned hair from entering the vacuum system, one or more internal circumferential ribs to create a turbulent flow within the handle, a reservoir to collect transected hair, and venturi apertures to regulate the suction pressure.

Abstract: A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply a negative pressure to the wound and a canister assembly. The canister assembly includes a control unit having a vacuum source and a controller and a collection canister in communication with the dressing assembly operable to receive fluid from the wound. The collection canister has a filter assembly having a filter and a passageway between the filter and a wall of the collection canister. The collection canister also includes a canister interface having a suction port, an inlet port, and a channel. The vacuum source draws air through the suction port from the channel which draws air from the passageway connected to the channel, the air in the passageway is drawn from the collection canister through the filter, and the air in the collection canister is drawn through the inlet port.

Abstract: An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. A biodegradable scaffold underlies the dressing on the wound bed to promote tissue growth. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing, an assembly comprising the dressing and scaffold, and a method of treatment using the apparatus.

Abstract: The invention relates to a device for treating bladder emptying dysfunctions of a human, in which a catheter that can be inserted into the urethra is provided with a bladder emptying channel and with a balloon arrangement, which serves to seal the bladder and to hold the catheter inside the bladder lumen and which can be filled with a fluid. In addition, an automatically closing valve having an elastically held closure part is provided in a proximal end area of the catheter and is connected via a connecting channel filled with an actuating fluid to an actuating balloon placed at the distal end section of the catheter. Without the use of mechanical means, the closure part can be lead out of a sealing system solely due to a hydraulic action effected by the actuating balloon via the hydraulic pressure built up in the connecting channel at said proximal end section.

Abstract: A diaphragm valve including a valve body, a diaphragm assembly and an actuator assembly having a housing body that isolates the actuator from the ambient atmosphere. The diaphragm assembly is welded to the valve body to reduce and/or eliminate fluid leakage around the diaphragm assembly. Additionally or alternatively, the housing body for the actuator assembly may be welded to the valve body to reduce fluid leakage. The welding may be performed using ultrasonic welding techniques.

Abstract: A throttle assembly including a bore wall to which a seal member is previously attached is inserted into a key-like slot of an intake air passage body, and flanges are fixed to each other by screws. A bore inner wall of the bore wall is placed to correspond to an inner wall of an intake air passage, and the seal member completely seals between the intake air passage body and the throttle assembly. That is, the throttle assembly including the seal member is inserted into the key-like slot, so that the throttle assembly is easily attached to the intake air passage body, a sealing mechanism therebetween is simplified, and a stress strain of the bore wall is prevented.

Abstract: An improved valve disc assembly that can be easily and conveniently disassembled and reassembled with accurate positioning of the valve disc within the through bore of the valve body. A split clamp ring is provided for securing the seat retaining ring and valve seat onto the valve body for sealing engagement with the valve disc. The shaft through which movement of the valve disc to and between open and closed positions is accomplished, also includes a detent that automatically positions the valve disc within the bore upon reassembly of the valve.
