|20120283678||CONTROLLED EVACUATION OSTOMY APPLIANCE - A controlled evacuation ostomy appliance comprises a pouch having a non-entrant stoma seal and a retainer for retaining the lower portion of the pouch in the folded-up condition. The appliance optionally includes a body fitment that may include a region of manually moldable adhesive for forming a custom fit at the stoma.||11-08-2012|
|20110060300||ASPIRATION SYSTEM FOR REMOVING LIQUID DISCHARGED BY THE BODY, AND LIQUID SENSOR THEREFOR - An aspiration system is disclosed for removing body liquid (e.g. urine or a secretion) discharged by the human body. The aspiration system comprises a body interface device with a liquid sensor, and an aspiration unit coupled to the body interface device. The liquid sensor comprises a temperature sensor and/or a resistance bridge. The aspiration unit includes: a vacuum chamber; a pump for pre-charging the vacuum chamber with a vacuum; a valve coupled between the vacuum chamber and the body interface device; and a control circuit for controlling the valve to apply aspiration suction from the vacuum chamber to the body interface device in response to detection of body liquid at the liquid sensor.||03-10-2011|
|20110040231||TEMPORARY OSTOMY APPLIANCE - A temporary ostomy appliance is disclosed, including a catheter for extending through the abdominal wall into the intestine. The catheter may be a transcecal catheter for extending through the cecal valve into the ileum. A portion of a catheter that extends through the cecal valve is made collapsible when the catheter is empty. The collapsed portion expands to permit passage of effluent. A balloon carried on the catheter is preformed with a shape and size in order to permit inflation without elastic stretching of the balloon wall material. A filament is provided for permitting a portion of the catheter to be fastened to internal body tissue by surgical sutures or staples. In order to release the fastening without further surgery, the filament is withdrawn by pulling on a proximal portion outside the body.||02-17-2011|
|20110039342||DIAGNOSTIC MARKERS OF WOUND INFECTION - A method of diagnosis or prediction of infection of a mammalian wound, said method comprising the step of detecting the presence of a cytokine selected from the group comprising procalcitonin, amino procalcitonin (N-ProCT), eotaxin, granulocyte macrophage colony stimulating factor (GM-CSF), interleukins IB monocyte chemotactic protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (MIP-1a), regulated upon activation normal T expressed and secreted (RANTES) in fluid taken from the wound. Also claimed is the device for use in the method.||02-17-2011|
|20110028923||DRAINABLE OSTOMY POUCH - A drainable ostomy pouch includes a collection portion and a drain chute extending from the collection portion having a discharge opening for permitting emptying of contents from the pouch. The drain chute is foldable between an open condition in which the drain chute is extended from the collection portion, and a closed condition in which the drain chute is folded towards the collection portion; and a pocket for receiving at least a portion of the drain chute when the drain chute is in its closed condition.||02-03-2011|
|20100234820||ASPIRATION SYSTEM AND BODY INTERFACE DEVICE FOR REMOVING URINE DISCHARGED BY THE HUMAN BODY - A body interface device for a urine aspiration system comprises a skin contact pad with gel adhesive for adhering to the skin, and a flexible cover attached to the pad. The pad includes at least one aperture for admitting urine through the pad into the body interface device. The flexible cover has a bulged form projecting away from the gasket. The flexible cover defines a urine receiving chamber facing towards the gasket, and recess facing away from the chamber for receiving at least a portion of a non-contact liquid sensor. The recess and chamber have a wall portion in common that separates the recess and the chamber. A liquid acquisition material in the chamber receives and transports urine for rapid sensing by the non-contact sensor. An aspiration unit is responsive to the non-contact liquid sensor to apply aspiration suction to the body interface device, upon detection of urine.||09-16-2010|
