Patent number: 6635009Abstract: A magnetic field applicator to heat magnetic substances in biological tissue, having a magnetic yoke with two pole shoes across from each other and separated from each other by a distance that defines the magnetic field exposure volume produced by the applicator, and with two magnetic coils, one assigned to each of the two pole shoes, to produce a magnetic field. The magnetic yoke and the pole shoes consist of ferrite segments assembled together. The pole shoes oppose each other and are surrounded by magnetic disk-shaped coils with one or more windings extending helicoidally, which creates an intermediate air gap between the pole shoes and coils. This results in a magnetic field applicator with the ability to effectively and efficiently administer hyperthermia and thermo-ablation procedures to destroy cancerous tissue in a patient, as well as having uses in other medical and industrial applications.Type: GrantFiled: January 18, 2001Date of Patent: October 21, 2003Assignee: MFH Hyperthermiesysteme GmbHInventor: Peter Feucht

Patent number: 5114424Abstract: A multipart planar electrode, suitable for use as a neutral electrode for an HF surgery device, has four sub-electrodes arranged on one side of a flexible, common carrier. At least three of these sub-electrodes have substantially the same area and at least two of the sub-electrodes have a limiting edge disposed parallel to and adjacent at least a portion of a separate edge of one of the remaining sub-electrodes. This insures that, if one of the sub-electrodes is used as an auxiliary electrode for a symmetry measurement of sub-currents, there will not be equality of the contact area of the electrodes with the patient's skin at the remaining sub-electrodes upon the occurrence of a straight-line release edge in an arbitrary direction. Because such equal areas will not occur, this will be detected by the symmetry measurement and an alarm indicating partial detachment of the electrode can be activated.Type: GrantFiled: August 27, 1990Date of Patent: May 19, 1992Assignee: Siemens AktiengesellschaftInventors: Uwe Hagen, Peter Feucht

Patent number: 5067953Abstract: For separating voltage potentials from a handle switch in a circuit for controlling an electro-therapy device, the circuit includes at least one electrode carrying high voltage connected to the switch, with the switch being in series with a rectifier and the series combination being electrically connected to a secondary side of a quadrupole component, which transmits alternating current and blocks direct current. The primary side of the quadrupole component is connected to an alternating current source, the secondary side being voltaically separated from the primary side. Actuation of the switch causes a directionally dependent change in an electrical parameter at the primary side of the quadrupole component. An evaluation unit is connected at the primary side, and is also connected to the electrode. The evaluation unit includes circuitry which is capable of altering the delivery of high voltage (a.c.Type: GrantFiled: May 11, 1990Date of Patent: November 26, 1991Assignee: Siemens AktiengesellschaftInventor: Peter Feucht

Patent number: 5000753Abstract: A neutral electrode for a high frequency surgery device has three planar sub-electrodes, which are arranged side by side on a carrier consisting of insulating material. To improve monitoring of the contact of the sub-electrodes with the body of the patient, the two outer sub-electrodes have substantially triangular contact surfaces, with the respective hypotenuses of the triangular contact surfaces proceeding parallel to and spaced from each other, with a central, strip-shaped sub-electrode disposed between the hypotenuses of the outer sub-electrodes. The neutral electrode is intended for use with a monitoring system which will activate an alarm if the neutral electrode becomes detached from the patient to such an extent that the danger of injury to the patient exists. This is accomplished by monitoring a current or currents flowing through the patient between sub-electrodes.Type: GrantFiled: January 30, 1990Date of Patent: March 19, 1991Assignee: Siemens AktiengesellschaftInventors: Uwe Hagen, Peter Feucht

Patent number: 4862889Abstract: An RF surgical apparatus has an RF power stage, a control circuit for driving the power stage, and an adjustable element for setting a rated value of the output power. To monitor the RF surgical apparatus for the occurrence of an apparatus-caused malfunction, a power measuring unit measures the actual value of the RF power at the output of the RF power stage. Deviations of the actual value from a rated value are monitored. An alarm is generated if the deviation exceeds a selected value. An alarm can be simulated in a test mode by means of an auxiliary circuit.Type: GrantFiled: January 19, 1989Date of Patent: September 5, 1989Assignee: Siemens AktiengesellschaftInventor: Peter Feucht

Patent number: 4770173Abstract: A multi-element electrode comprises at least two flat partial electrodes which are arranged in juxtaposition to a pre-established direction. To simplify the fabrication of such an electrode and in particular to allow the use of cable conductors of equal length for attachment thereto, provision is made for the two partial electrodes to exhibit facing edges which are at an angle to the pre-established direction. Such a construction is advantageous in the case of a three-part electrode. The electrode is preferably the neutral electrode of an HF-surgical apparatus.Type: GrantFiled: April 7, 1987Date of Patent: September 13, 1988Assignee: Siemens AktiengesellschaftInventors: Peter Feucht, Uwe Hagen, Hans-Juergen Meyer, Udo Redler
