  • Publication number: 20070141105
    Abstract: Biocompatible matrices or implants on which one or more specific cell-interactive molecules (“biomolecules”) can be immobilized have been developed. The matrices allow for the independent control of ligand concentration and matrix strength. In one embodiment, the matrix or implant is modified with one or more moieties capable of complexing bioconjugates prepared from one or more biomolecules. Suitable moieties include phenyl boronic acid complexing agents, such as salicylhydroxamic acid, which can complex to one or more biomolecules containing one or more phenyl boronic acid moieties. The biomolecules may be anchored to the matrix via a spacer molecule, which may allow for greater mobility of the biomolecules in aqueous solution. In one embodiment, the matrix is a hydrogel material which has been doubly-derivatized, wherein ligand concentration and matrix strength can be independently controlled.

  • Publication number: 20040167517
    Abstract: The disclosure provides a probe arrangement having a distal probe tip and a proximal hand portion for the electrothermal coagulation of tissue. The probe arrangement has at least a first and a second electrode in the region of the distal probe tip. An inner conductor of the probe arrangement extends from the distal probe tip to the proximal hand portion and contacts the first electrode in the distal probe tip. An outer conductor of the probe arrangement extends from the distal probe tip to the proximal hand portion and serves to electrically contact the second electrode in the distal probe tip. The inner and outer conductors of the probe arrangement are electrically insulated from each other. Furthermore the inner conductor is selected in such a way that the flexural stiffness of the probe arrangement is increased between the probe tip and the hand portion.

  • Publication number: 20040158952
    Abstract: An exhaust filter unit is arranged outwardly surrounding at least a major portion of a housing of a vacuum cleaner. The dirt-laden incoming airflow is filtered through a primary filter, then blown by a suction motor unit into an annular exhaust air space between the vacuum cleaner housing and the exhaust filter unit. Thereby, the filtered air is exhausted in a diffused manner through the large surface area of the exhaust filter unit. Preferably, the exhaust filter unit has a cylindrical tubular configuration that completely externally surrounds a cylindrical portion of the vacuum cleaner housing.

  • Publication number: 20040154114
    Abstract: A brush roller accessory for a vacuum cleaner includes a main support roller and a power-driven brush roller rotatably arranged in a housing, and a spring-biased adjusting roller that adjustably protrudes from the housing to bear some of the total contact force of the accessory against a floor, to reduce or relieve the contact force exerted by the brush roller against the floor. The adjusting roller is rotatably mounted on a pivot lever, having a first end pivotally connected to the housing and a second end connected to a spring that biases the lever to pivot the adjusting roller outwardly from the housing. A rotary knob with several stop surfaces selects an upper limit on the pivot range of the lever and the adjustment height of the adjusting roller. A coupling link pivots the adjusting roller to a maximally protruding position to lift the brush roller into a parking position.
