20090306642 | METHOD FOR LOW TEMPERATURE ELECTROSUGERY AND RF GENERATOR - Method and apparatus for electrosurgery including tissue coagulation using very high voltage pulses of electrical energy applied to the electrosurgical probe. This minimizes heating of the surrounding tissue in the probe and is especially suitable for precise and limited coagulation and fulguration without excessive tissue charring or other damage. The power at rated load of the applied pulses to the probe is typically over 300 W and the duration of the on time is very short, so each group of pulse bursts is of relatively low duty cycle. An RF generator is also provided for delivering electrical energy to an electrosurgical probe with the proper characteristics, including fast switching times. | 12-10-2009 |
20120165814 | METHOD AND DEVICE FOR NON-THERMAL ELECTRICALLY-INDUCED CLOSURE OF BLOOD VESSELS BY OCCLUSION - Methods and devices for the non-thermal, electrically-induced temporary or permanent closure of blood vessels. Methods and devices employ pulsed electrical energy according to a defined regime to effect controlled occlusion of targeted blood vessels without heating the vessel and with minimal damage to adjacent tissue. The extent of vessel closure, i.e., temporary (vasoconstriction) or permanent (thrombosis), is controlled based on the manipulation of various parameters of the electrical stimulation regime as well as the configuration of the electrodes used to apply the regime. | 06-28-2012 |
20120191084 | ELECTROSURGERY APPARATUS WITH PARTIALLY INSULATED ELECTRODE AND EXPOSED EDGE - Electrosurgery method and apparatus. In the method, tissue is cut or coagulated, with an electrically low conductive liquid providing cooling. In another method, skin is cut by electrosurgery in a dry field using a low duty cycle signal energizing the cutting electrode, minimizing tissue charring. A combination coagulation and cutting electrode performs both functions. The cutting is performed by a blade edge generating a local plasma adapted for cutting. Superimposed on the blade edge is an electrode of greater surface area electrically insulated from the cutting electrode, for coagulation. In another version, a single component cutting/coagulation blade (electrode) has a cutting and a flat partially insulated portion defining through holes in the insulation for coagulation. Also provided is an electrical circuit whereby each electrode is isolated by a filter from cross talk and feedback of the RF signal from the other electrode, minimizing arcing. | 07-26-2012 |
20120296330 | DEVICE FOR NON-THERMAL, ELECTRICALLY-INDUCED CLOSURE OF BLOOD VESSELS BY OCCLUSION - Devices for the non-thermal, electrically-induced temporary or permanent closure of blood vessels. The subject devices employ pulsed electrical energy according to a defined regime to effect controlled occlusion of targeted blood vessels without hating the vessel and with minimal damage to adjacent tissue. The extent of vessel closure, i.e., temporary (vasoconstriction) or permanent (thrombosis), is controlled based on the manipulation of various parameters of the electrical stimulation regime as well as the configuration of the electrodes used to apply the regime. | 11-22-2012 |

20090239046 | Method for Printing a Surface - A hot-film embossing method for printing a surface and a corresponding embossing film, in particular for printing a plastic surface. The embossing film has at least one patterned layer or ink layer and one melt layer. The embossing film is pressed against the surface by means of an embossing ram, whereby a heat input into the melt layer is achieved by means of high-frequency radiation. | 09-24-2009 |
20090241279 | METHODS OF MANUFACTURING TOOTHBRUSHES - A method is provided for manufacturing a function element carrier with function elements, for example, individual tufts made up of bristles and/or massage elements, interproximal cleaning elements, or other elements designed to be fastened to a toothbrush and also perform special functions. The function elements are equipped at their ends intended for anchoring in a toothbrush with an anchor, retainer or axle element. The method includes: (a) inserting several function elements in corresponding recesses of an injection mold, said injection mold being connected via grid or bar shaped channels formed in a die to recesses in the areas of the anchoring ends of the function elements; (b) filling the grid or bar shaped channels with liquefied plastic material and injecting said material at the anchoring ends of the function elements or embedding them therein; and (c) allowing the plastic material to cool and removing a function element carrier made up of a grid or bar shaped plastic frame and the function elements. Function element carriers and toothbrushes are also provided. | 10-01-2009 |
20130326834 | Brush Head And Method And Tool For Producing The Same - A method for producing a brush head for a toothbrush head is disclosed. The method includes the steps of providing a bristle carrier; providing cleaning elements having first ends which will not be embedded in the bristle carrier and second ends which will be embedded in the bristle carrier, wherein the cleaning elements are selected from at least two different types of cleaning elements or at least two distinctive cleaning elements of the same type; placing the first ends of the cleaning elements in the bristle carrier in a carrier part for holding; and supplying different amounts of heat to the second ends in the bristle carrier by reflecting the heat supplied partially from the carrier part and/or absorbing the heat supplied partially by the carrier part resulting in the second end being molten. | 12-12-2013 |
