Patent number: 8221406Abstract: A high frequency current application apparatus for thermal sclerosing of body tissue, comprising a high frequency generator connected to at least two electrodes, one of which is to be introduced into body tissue. The apparatus includes a measuring and calculating device adapted to ascertain impedance (or ohmic resistance) between the two electrodes between which a respective therapeutic high frequency current flows. A control device is connected to the measuring and calculating device for varying the output power. During high frequency current application the measuring and calculating device forms the first derivative with respect of time of the impedance. The control device reduces output power when that derivative exceeds a positive threshold characteristic of a threat of tissue desiccation and restores output power to the original power when the first derivative exceeds in positive values a negative threshold characteristic of adequate rehydration of body tissue.Type: GrantFiled: August 19, 2005Date of Patent: July 17, 2012Assignee: Celon AG Medical InstrumentsInventors: Kai Desinger, Thomas Stein, André Roggan, Thomas Prezewowsky

Patent number: 8216219Abstract: An electrode array is used for the thermal schlerosing of body tissue. The electrode array has at least three active electrodes that, during use, are placed in electrical-conducting connection with body tissue. A high frequency generator is electrically connected for selective application of current to the active electrodes for producing a high frequency voltage. A measuring device measures impedance of the tissue between the active electrodes. In addition, a selector device selects a sub-array including at least two active electrodes from the electrode array, the selecting being effected on the basis of the measured impedance. Further, a control device is configured such that a high frequency voltage is respectively applied between the active electrodes of the selected sub-array in such a way that a high frequency current flows between the selected active electrodes through the body tissue.Type: GrantFiled: May 23, 2003Date of Patent: July 10, 2012Assignee: Celon AGInventors: Kai Desinger, Thomas Stein, Andre Roggan, Thomas Prezewowsky
