Abstract: An endoscope reprocessor for reprocessing an endoscope. An actuation mechanism of the reprocessor includes an actuator housing and a plunger removably attachable to an elevator guidewire lever of the endoscope. A receiving chamber receives pressurized fluid from a pump to impart a pressurized fluid biasing force that displaces the plunger relative to the actuator housing in a first direction and a return actuator that imparts a return biasing force that displaces the plunger relative to the actuator housing in a second direction. A controller controls the pump to provide the pressurized fluid at a first pressure at which the pressurized fluid biasing force is greater than the return biasing force to displace the plunger lever in the first direction and a second pressure at which the return biasing force is greater than the pressurized fluid biasing force to displace the plunger and the lever in the second direction.

Abstract: A liquid sporulation method is described. A first liquid culture is prepared by adding bacterial cells to a sporulation broth, wherein an optical density (OD600) of the first liquid culture is in a range of 0.001 to 0.01. The first liquid culture is incubated and an optical density (OD600) thereof is increased to be in a range of 0.2 to 2.0. Second liquid culture is prepared by adding the incubated first liquid culture to a predetermined amount of additional sporulation broth, wherein an optical density (OD600) of the second liquid culture is in the range of 0.001 to 0.1, and a ratio of a volume of the second liquid culture to a volume of the first liquid culture is in a range of 10:1 to 150:1. The second liquid culture is incubated so an optical density (OD600) thereof is increased to be in a range of 1.0 to 4.0.

Abstract: A device and method for testing for the presence of liquid in a cannula of a medical instrument is described. The device includes a flexible guide member having a first end, a second end and a length extending from the first end to the second end, an elongated member arranged within the flexible guide member, and an absorbent material attached to one of the elongated member. The flexible guide member is inserted into the cannula, the flexible guide member is manipulated to cause the absorbent material to move through the cannula. The absorbent material is analyzed for the presence of liquid.

Abstract: A light system monitors an area of interest for exposure to radiant energy provided by an operating room light head. At least one operating parameter of the light head is obtained, and based on the at least one operating parameter it is determined if the area of interest has been or will be exposed to radiant energy exceeding a prescribed threshold over a prescribed time period. Based on the determination, the system at least one of automatically adjusts an operating setting of the at least one light head or generates a warning of possible overexposure to radiant energy in the area of interest.

Abstract: This invention relates to a chemical indicator, comprising: a non-cellulosic backing layer; a non-cellulosic cover layer overlying the backing layer; the backing layer and/or the cover layer comprising a gas permeable polymeric film; a non-cellulosic wicking material positioned between the backing layer and the cover layer; a dye composition positioned between the backing layer and the cover layer and in contact with or nearly in contact with the wicking strip, the dye composition comprising an indicator dye which changes color in the presence of hydrogen peroxide, and a base medium, which melts at a temperature in the range from about 45° C. to about 65° C.; the cover layer including a transparent portion to permit observation of the wicking material; and an adhesive for adhering the cover layer to the backing layer. The chemical indicator may be referred to as a moving front chemical indicator. A process for conducting a vaporous hydrogen peroxide (VHP) sterilization process using the foregoing chemical indicator is disclosed.

Abstract: A method of sterilizing material includes receiving the material in a sterilizing chamber, vaporizing sterilant supplied to vaporizer from a sterilant source, exposing the material to the vaporized sterilant by conducting a sterilization cycle in the sterilizing chamber, heating ambient filtered air supplied to the vaporizer from an ambient filtered air source, and removing residuals of the vaporized sterilant absorbed or adsorbed by the material during the sterilization cycle by conducting an aeration cycle in the sterilizing chamber. The removing of the residuals includes conducting a plurality of aeration pulses to provide the sterilizing chamber with an aeration atmosphere comprising the heated filtered air to vaporize the absorbed or adsorbed residuals, and conducting a plurality of aeration vacuum pulses to evacuate the aeration atmosphere and vaporized residuals from the sterilizing chamber.

Abstract: A medical device support system including a shaft, extension arm, and floating stop. A guide channel member is fixed to the shaft and includes an elongated cavity that defines first and second contact faces at its opposite ends. A hub of the extension arm is pivotably mounted for a range of at least 360 degrees rotation about a rotation axis of the shaft. The at least 360 degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outer portion of the floating stop. The second rotation range is defined by a radially inner portion of the floating stop configured to move between the first and second contact faces of the elongated cavity of the guide channel member.

Abstract: A steam sterilizer having a door movable relative to an opening between a first open position and a second closed position. A plurality of spaced-apart roller assemblies are aligned along edges of the door to align the door relative to the opening as the door moves between the open and closed position. Each of the roller assemblies are comprised of a cylindrical roller having an outer annual recess extending along the periphery thereof. The recess is dimensioned to receive a lateral edge of the door. The roller is mounted on a shaft and is movable against a biasing force axially along the axis of the shaft.

Abstract: A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate.
