Risk Assessment for Power Supplies to Comply with IEC 60601-1 3rd Edition
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Monitoring & Testing, FDA Compliance/Regulatory Affairs, Electronics, Power Supplies, Power Management, Medical, Features, MDB on Tuesday, 01 January 2013
For medical device OEMs seeking compliance to the 3rd Edition of IEC 60601-1 for their power supplies, what is quite clear by now are the regional dates for enforcement, the required risk management at the medical electrical equipment or system level, the new definitions of Means of Operator Protection (MOOP) and Means of Patient Protection (MOPP), and other differences as compared to the 2nd Edition. What is not clear is how to address these new definitions and requirements. Rather than simply redesigning and resubmitting for 3rd Edition certification, questionnaires and flowcharts that map out the requirements at the device or system level help to minimize the evaluation and redesign at the power supply level. By having the medical device OEM and power supply vendor answer the questionnaire concurrently, deficiencies from the equipment or power supply can be quickly assessed in order to satisfy the requirement.

Defibrillator Setting Change Leads to Health Gains
Posted in Electronics, Implants & Prosthetics, Medical, News, MDB on Wednesday, 28 November 2012
A new study shows that many implantable cardioverter defibrillators (ICDs), which are designed to detect and correct dangerous heart rhythms, are programmed to too low a setting, delivering painful shocks for heart rhythms that aren’t dangerous. Making a simple change in the way physicians set or program the device can lead to a dramatic 80 to 90 percent reduction in inappropriate therapies delivered for rhythms not life threatening. Cardiology researchers at the University of Rochester Medical Center, Rochester, NY, found that simply raising the heart rate at which the device is set to fire significantly increased survival, lowering the risk of death by 55 percent compared to patients whose devices used traditional programming. This is above and beyond the usual decrease in mortality associated with defibrillator therapy, leading to an overall 70 percent reduction in death.
