Patent application numberDescriptionPublished
20090204060Flexible Application Device for the High-Frequency Treatment of Biological Tissue - The invention concerns a flexible application device (08-13-2009
20090275938HIGH FREQUENCY GENERATOR FOR ELECTROSURGICAL CUTTING - The invention concerns a high frequency generator for the connection of an electrosurgical instrument comprising an electrical output terminal for an electrosurgical instrument, a current or voltage source connected at least indirectly to the output terminal, an arc detector, and a power control for controlling the electrical power delivered by way of the output terminal, wherein the power control is adapted firstly to cause the delivery of a high output power for a phase for the initial cutting support and subsequently thereto either if ignition of an arc has occurred during the phase for initial cutting support for a predetermined period of time of a cutting phase to cause the delivery of a power which is reduced in relation to the high power and subsequently for a predetermined period of time of a long pause interval to cause the delivery of no power or a lower power at which no arc occurs, or if no ignition of an arc has occurred during the phase for initial cutting support to cause the delivery of no power or a lower power for a predetermined period of time of a short pause interval.11-05-2009
20090299366THERAPY DEVICE FOR THERMAL SCLEROSING OF BODY TISSUE - The application arrangement according to the invention for applying a high frequency current for thermal sclerosing of body tissue, includes: 12-03-2009
20090306656Therapy apparatus for thermal sclerosing of body tissue - The application arrangement according to the invention for applying a high frequency current for thermal sclerosing of body tissue, includes: 12-10-2009
20100087814DEVICE FOR CUTTING AND COAGULATING TISSUE - The invention concerns an application device for electrosurgical cutting and coagulation of body tissue, wherein the instrument is in the form of a gripping instrument having two gripping arms which are movable relative to each other and which each have at their distal end at least two respective electrodes, namely at least one coagulation electrode and at least one cutting electrode.04-08-2010
20100093226MEDICAL TECHNOLOGY DEVICE AND MEDICAL TECHNOLOGY DEVICE ARRANGEMENT - The invention concerns a medical technology device for treatment of the human or animal body, comprising at least one electrical plug connector which is adapted to be connected to a complementary counterpart plug connector of a further medical technology device and which in an active position is arranged projecting upwardly at the top side of the device. To provide a medical technology device which can be used both as an individual device and also in conjunction with a second device as a device arrangement and which in that respect satisfies existing safety and aesthetic demands, it is provided in accordance with the invention that the plug connector is adapted to be movable from the active position into a passive position, wherein in the passive position the plug connector is removed from the top side of the device and the top side is closed in substantially fluid-tight relationship.04-15-2010
