    Abstract: Disclosed are devices and methods for treating disease in a urinary bladder. The devices include a bladder liner for insertion into the urinary bladder and catheters positioned within the urinary bladder to carry urine from the ureters to an outside collection container. The bladder liner and catheters are constructed of biocompatible materials and are configured to create a seal with the urethra and ureters. The bladder liner may be adapted to deliver medicinal agents to the urinary bladder. Methods of treating disease in the urinary bladder include isolating urine from the bladder wall to allow sufficient time for the bladder wall to heal e.g., by implanting the aforementioned devices. Healing or pain relief may be enhanced by instilling pharmaceutical agents between the liner and bladder wall without dilutional effects.

  • Patent number: 6096007
    Abstract: A pressure container for applying pressure to a flexible bag received in it and filled with a medical fluid, in order to deliver the fluid from the flexible bag, has a housing that has an opening for introduction of the bag. Also provided are a cover for covering the opening, an aperture for leading a fluid discharge line of the bag out of the pressure container, and a closure for sealed joining of the cover and housing. In the interest of simpler design and easier handling, it is proposed that the housing be configured as an upright hollow-cylindrical body, closed at the bottom and open at the top, the cross section of which has a flattened oval shape and corresponds roughly to the cross-sectional contour of a bag; and that the two opposing large-area upright sidewalls each have, in mirror-image fashion, the shape of a segment of a cylindrical shell whose lateral ends are joined by joining segments.

  • Patent number: 6017318
    Abstract: A feedback controlled drug delivery system includes the automated sampling and analysis of a patient sample and dosing the patient based on the analysis. Automated sampling may be performed by direct analysis of the patient sample, such as for the measurement of a blood sample coagulation state or a glucose level. The drug delivery system includes a sample set that has a bidirectional patient tube that allows for delivery of the patient sample to an analyzer, and at another time, the infusion of a therapeutic drug. A controller receives a measurement from the analyzer, and based on that measurement, adjusts the delivery of the therapeutic fluid. The sample set has a quick--clear Leur fitting that allows for more effectively clearing a first fluid from a Leur fitting when starting a second fluid. The system also has a reagent cassette holder that protects, using a foam gasket, a reagent on a sample slide.

  • Patent number: 5935100
    Abstract: A method and infusion set for consecutively draining liquid medicines from a plurality of containers, such as two containers (1, 2) containing said liquid medicines, the liquid medicine via a differential pressure valve (5a) is fed into a drip chamber (6), wherein the fluid flow is permitted initially from one container (1) by the higher fluid pressure and differential force area from the first container (1) on a diaphragm disk (15), whereby the fluid flow from the second container (2) is stopped and, later an automatic switch to a second container (2) as a source of fluid is effected when the fluid flow from the almost drained first container (1) is at a lower fluid pressure and a smaller differential force area and is exceeded by a higher fluid pressure of the second container (2) and the larger differential force area.

  • Patent number: 5695478
    Abstract: Safety connector for infusion therapy for supplying several lines and having a casing (1) in which there is a chamber (4) that is bordered by an essentially cylindrical inside wall (5) of the casing into which several connecting channels (2) for joining infusion lines open and which has an outlet channel (9) for attaching an outlet line. The cylindrical outside wall of an elastic ring-shaped valve body is in contact with the inside wall (5) of casing (1) that surrounds chamber (4). The safety connector is simple and inexpensive and has an uncomplicated design. The cylindrical contact surfaces between the ring-shaped valve body and the cylindrical inside wall (5) surrounding chamber (4) result in a good seal for the non-return valves even at a low contact pressure. The sealing force can be determined even down to a very low pressure. Thus, for the first time a safety connector suitable for gravity infusion systems is available.
