| 20110009916 | METHOD AND DEVICE FOR THREE-STAGE ATRIAL CARDIOVERSION THERAPY - Methods and apparatus for a three-stage atrial cardioversion therapy that treats atrial arrhythmias within pain tolerance thresholds of a patient. An implantable therapy generator adapted to generate and selectively deliver a three-stage atrial cardioversion therapy and at least two leads operably each having at least one electrode adapted to be positioned proximate the atrium of the patient. The device is programmed with a set of therapy parameters for delivering a three-stage atrial cardioversion therapy to the patient via both a far-field configuration and a near-field configuration of the electrodes upon detection of an atrial arrhythmia. The three-stage atrial cardioversion therapy includes a first stage for unpinning of one or more singularities associated with an atrial arrhythmia, a second stage for anti-repinning of the one or more singularities associated with the atrial arrhythmia, both of which are delivered via the far-field configuration of the electrodes, and a third stage for extinguishing of the one or more singularities associated with the atrial arrhythmia delivered via the near-field configuration of the electrodes. | 01-13-2011 |

| 20090204164 | METHOD AND DEVICE FOR LOW-ENERGY TERMINATION OF ATRIAL TACHYARRHYTHMIAS - Methods for treating atrial arrhythmias can involve configuring an implantable arrhythmia treatment device. A device can be configured after implantation when the patient is fully conscious and after any pain suppression medication has worn off. The device is caused to apply a phased unpinning far field therapy to the patient in response to detection of an arrhythmia via a far field configuration of electrodes. An indication of a pain sensation of the patient and the effectiveness of the treatment in response to the therapy can then be received. In response, at least one of a set of therapy parameters is adjusted and the steps are repeated until it is determined that an effective treatment is provide at a pain sensation that is tolerable to the patient. The device is then programmed to automatically treat arrhythmias detected in the patient with the determined set of therapy parameters. | 08-13-2009 |

| 20080314883 | Laser Processing Method and Equipment - A laser processing method and apparatus capable of forming an extremely minute modified area not exceeding half the diffraction limit value of the laser wavelength used for processing without causing plasma in a processing object such as a dielectric material substrate or semiconductor material substrate. In this technology, attention is paid to the fact that new damage is caused even at laser intensity that does not cause plasma at all, and a laser beam ( | 12-25-2008 |

| 20100118295 | System and Method for Measuring a Laser-Induced Damage Threshold in an Optical Fiber - A system for measuring a laser-induced damage threshold in an optical fiber may include a lens to direct a first laser beam through a core of the optical fiber. The system may also include an optical arrangement to direct a second laser beam through an exterior surface of the optical fiber and into the core of the optical fiber at a preselected location of the optical fiber to provide a predetermined power density at the preselected location, wherein the optical arrangement causes the second laser beam to be directed into the optical fiber substantially completely around a perimeter of the optical fiber to provide the predetermined power density. | 05-13-2010 |
