27、 EXAMPLE COCHLEAR IMPLANT SYSTEMS or AUDITORY BRAINSTEM IMPLANT SYSTEMS), to provide basic assurance of safety for both patients and users. A COCHLEAR IMPLANT SYSTEM or AUDITORY BRAINSTEM IMPLANT SYSTEM is an ACTIVE IMPLANTABLE MEDICAL DEVICE comprising implantable and NON-IMPLANTABLE PARTS (externa
28、l parts). The power source may be externally derived or from an internal battery. The IMPLANT SYSTEM is designed to restore hearing via electrical stimulation of the auditory pathways. Externally or internally processed acoustic information is converted to electrical stimulation signals which are de
29、livered via one or more electrodes. The working parameters of the device may be adjusted via a non-implantable accessory. This European Standard is relevant to all parts of IMPLANT SYSTEMS, including accessories. The requirements of this European Standard supplement or modify those of EN 455021:1997
30、, Active implantable medical devices Part 1: General requirements for safety, marking and information to be provided by the manufacturer, hereinafter referred to as Part 1. The requirements of this European Standard take priority over those of Part 1. Figures or tables that are additional to those o
31、f Part 1 are numbered starting from 101; additional annexes are lettered AA, BB, etc. BS EN 45502-2-3:2010EN 45502-2-3:2010 6 1 Scope This Part 2-3 of EN 45502 specifies requirements that are applicable to those ACTIVE IMPLANTABLE MEDICAL DEVICES that are intended to treat hearing impairment via ele
32、ctrical stimulation of the auditory pathways. Devices which treat hearing impairment via means other than electrical stimulation are not covered by 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. Thi
33、s Part of EN 45502 is also applicable to NON-IMPLANTABLE PARTS and accessories of the devices (see NOTE 1). The electrical characteristics of the IMPLANTABLE PART shall be determined by either the appropriate method detailed in this particular standard or by any other method demonstrated to have an
34、accuracy equal to, or better than, the method specified. In the case of dispute, the method detailed in this particular standard shall apply. NOTE 1 The device that is commonly referred to as an active implantable medical device can in fact be a single device, a combination of devices, or a combinat
35、ion 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 part.
36、 NOTE 2 The terminology used in this European Standard is intended to be consistent with the terminology of Directive 90/385/EEC. NOTE 3 In this European Standard, terms printed in small capital letters are used as defined in Clause 3. Where a defined term is used as a qualifier in another term, it
37、is not printed in small capital letters unless the concept thus qualified is also defined. 2 Normative references This clause of Part 1 applies except as follows: Additional references: EN ISO 14971 1)2007 Medical devices - Application of risk management to medical devices (ISO 14971:2007) EN 1593 1
