| 20110106190 | Defibrillator Having a Secure Discharging Circuit Comprising an H-Bridge - The invention relates to a cardiac defibrillator used to treat a patient in cardio-circulatory arrest by a shock from a dosed biphasic discharge from a capacitor through an H-bridge comprising a high-voltage switch A, B, C or D in each of the limbs thereof. Said cardiac defibrillator is characterised in that each opposing polarity phase of the biphasic shock is controlled in two stages in such a way that, for each pair of switches associated with a phase, the first switch is switched on and remains on during the entire phase, while the second switch switches off in a staggered manner in relation to the first switch for a controlled amount of time in order to pass the current through the patient during said phase, the same process being carried out for the second phase with the other pair of switches. The invention is especially suitable for manufacturers of defibrillation appliances. | 2011-05-05 |
| 20110106191 | IMPLANTABLE MEDICAL DEVICE NOISE MODE - Techniques for activating an alternative operating mode in an implantable medical device based on a determination that the device is within a relatively high noise environment or otherwise exposed to relatively high noise. The implantable medical device can automatically detect its presence in a high noise environment and automatically revert to the alternative operating mode, the device may be manually switched to alternative operating mode, or a hybrid manual/automatic approach may be used to switch the device to alternative operating mode. | 2011-05-05 |
