Título Implants for surgery - Active implantable medical devices - Part 1: General requirements for safety, marking and for information to be provided by the manufacturer
Resumo This part 1 of EN 45502 specifies requirements that are generally applicable to active implantable medical devices. For particular types of active implantable medical devices, these essential requirements are supplemented or modified by the requirements of particular standards which form additional parts of this European Standard. The tests that are specified in EN 45502 are type tests and are to be carried out on samples of a device to show compliance. This part of EN 45502 is applicable not only to active implantable medical devices that are electrically powered but also to those powered by other energy sources (for example by gas pressure or by springs). This part of EN 45502 is also applicable to some non-implantable parts and accessories of the devices. The device that is commonly referred to as an active implantable medical device may in fact be a single device, a combination of devices, or a combination of a device or devices and one or more accessories. Not all of these parts are required to be either partially or totally implantable, but there is a need to specify some requirements of non-implantable parts and accessories if they could affect the safety or performance of the implantable device. The terminology used in this European Standard is intended to be consistent with the terminology of Directive 90/385/EEC.

Título Medical electrical equipment: Part 1-2: General requirements for safety - Collateral standard: Electromagnetic disturbances - Requirements and tests
Resumo Specifies requirements and tests for electromagnetic compatibility of medical electrical equipment and medical electrical systems and serves as the basis of electromagnetic compatibility requirements and tests in Particular Standards. The existence of electromagnetic emission requirements is essential for the protection of: - safety services; - other medical electrical equipment and medical electrical systems; - non-medical electrical equipment (e.g. computers); - telecommunications (e.g. radio/TV, telephone, radio-navigation). The existence of electromagnetic immunity requirements is essential to assure safety of equipment and systems. The immunity test levels specified in this standard (EN 60601 test levels) represent the range found in the general medical use environment.

Título Radiofrequency Interference with Medical Devices
Resumo The past few years have seen increased reports that medical devices, such as pacemakers, apnea monitors, electrically powered wheelchairs, etc., have failed to operate correctly because of interference from various emitters of radiofrequency energy. This condition is called radiofrequency interference (RFI). The consequences of these failures range from inconvenience to serious injuries and death. Reasons for this problem are twofold: 1) increasing numbers of electronically controlled medical devices with inadequate electronic protection against RFI, and 2) a significant increase in the number of RF sources in the environment. Medical devices are widely used outside the hospital and may be attached to, or implanted in, patients. Portable wireless communications equipment, including cellular phones, handheld transceivers, and vehicle mounted transceivers, comprise one of the largest sources of RFI. Some medical devices are especially sensitive to the type of digital modulation that some of the wireless communications devices utilize. (...) COMAR recommends that the various parties involved in the manufacture and use of RFI prone medical devices take steps to avoid serious RFI problems that may lead to safety hazards. Medical device manufacturers should design and test their products to ensure conformance with current RFI standards and educate the users of their devices about the possible symptoms of potential RFI. If there exists the possibility of RFI problems to medical devices, steps should be taken to ensure that all sources of RF energy be kept at a sufficient distance.
