20100155053DOWNHOLE FLUID COMMUNICATION APPARATUS AND METHOD - A probe for establishing fluid communication between a downhole tool and a subterranean formation is provided. The downhole tool is positioned in a wellbore penetrating the subterranean formation. The probe includes a platform operatively connected to the downhole tool, at least one packer operatively connected to the platform, the packer having at least one hole extending therethrough and at least one embedded member disposed in the packer for enhancing the operation of the packer as it is pressed against the wellbore wall.06-24-2010

20080234622Methods and Systems for Preparing Blood Products - The present invention is related to pre-connected disposable sets including a pre-connected bag containing a photosensitizer for use in a blood separation and pathogen inactivation procedure.09-25-2008
20080299538Pathogen Inactivation of Whole Blood - This invention is directed toward a method of pathogen inactivating whole blood. The steps include collecting whole blood from a donor into a bag; illuminating the whole blood with light at a sufficient energy so that an alloxazine photosensitizer present in the whole blood may be photolyzed to inactivate any pathogens which may be present in the whole blood; and storing the pathogen inactivated whole blood. The invention also includes a method of separating the pathogen inactivated whole blood into components.12-04-2008
20090010806Apparatus for Photo Reduction of Contaminants in Blood and Blood Products with Calibration Means - An apparatus for irradiating blood or blood products, preferably with ultra violet or visible light, to reduce contaminants in the blood or blood products. A removable radiometer having light integrating chambers detects the light intensity, allowing the radiation characteristics of the apparatus to be calibrated. A control circuit uses the measurements to control the delivery of an effective dose of illumination to blood or blood products in a bag or container. One or more light integrating optical chambers in the radiometer allow a single light sensor to sense light across an entire field. Thermistors in the irradiating apparatus or the radiometer or both sense the temperature of photo sensors. The control circuit compensates for temperature-dependant variations in the output of the photo sensors.01-08-2009
20090317296Clamp Assembly for Displacing Fluid from Portions of Fluid Containers - Clamps and methods are disclosed for clamping portions of fluid containers and displacing fluid from portions of fluid containers. In one embodiment, a clamp has a first jaw having a photopermeable main body portion and a second jaw. The first and second jaws are operatively associated so that at least one jaw, or both jaws, may be moved between clamped and released positions. The clamp is sized to receive a portion of a fluid container and displace fluid in the fluid container from a clamped region of the fluid container when the first and/or second jaw(s) are in the clamped position. The photopermeable main body portion(s) of the first and/or second jaw(s) allow some light to reach the clamped region of the fluid container during photoradiation to inactivate pathogens in the fluid. Various clamp embodiments and assemblies having lock members and interlocks are also disclosed herein.12-24-2009
20100189597Methods and Systems for Preparing Blood Products - The present invention is related to pre-connected disposable sets including a pre-connected bag containing a photosensitizer for use in a blood separation and pathogen inactivation procedure.07-29-2010
20100282980Stable Calibration Means for Apparatus for Photo Reduction of Contaminants in Blood - An apparatus for irradiating blood or blood products, preferably with ultra violet or visible light, to reduce contaminants in the blood or blood products. A removable radiometer having light integrating chambers detects the light intensity, allowing the radiation characteristics of the apparatus to be calibrated. The light chambers have an aluminum reflecting surface prepared by machining, grit blasting, polishing and plasma treatment including plasma cleaning and oxidation.11-11-2010
