Foreword
YY 0989 “Implants for Surgery – Active Implantable Medical Devices” consists of the
following 7 parts:
--- Part 1: General Requirements for Safety, Marking and for Information to be
Provided by the Manufacturer;
--- Part 2: Cardiac Pacemakers;
--- Part 3: Implantable Neurostimulators;
--- Part 4: Implantable Infusion Pumps;
--- Part 5: Circulatory Support Devices;
--- Part 6: Particular Requirements for Active Implantable Medical Devices Intended
to Treat Tachyarrhythmia (Including Implantable Defibrillators);
--- Part 7: Particular Requirements for Cochlear Implant Systems.
This Part is Part 7 of YY 0989.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part adopts the redrafting method to modify-adopt ISO 14708-7:2013 Implants for
Surgery – Active Implantable Medical Device – Part 7: Particular Requirements for
Cochlear Implant Systems. Compared with ISO 14708-7:2013, this Part has the major
technical changes as follows:
--- Modify the formulation format according to GB/T 1.1-2009;
--- Delete the cover, foreword and introduction from the standard ISO 14708-7:2013
(the first edition);
--- For the international standards cited in this Standard, if they have been converted
into China’s domestic standards, then quote Chinese standards;
--- According to the requirements of the Chinese version, modify the page number,
font and font size, etc.; which shall not affect the degree of consistency;
--- Delete Annexes AA and BB from the standard ISO 14708-7:2013 (the first
edition).
Please note some contents of this document may involve patents. The issuing agency
of this document shall not assume the responsibility to identify these patents.
This Part was proposed by China Food and Drug Administration.
This Part shall be under the jurisdiction of Subcommittee for Standardization of Medical
Electronic Instrument under National Technical Committee for Standardization of
Medical Electrical Equipment (SAC/TC 10/SC 5).
Drafting organization of this Part: Shanghai Testing and Inspection Institute for Medical
Device.
Chief drafting staffs of this Part: Zhang Diedong, Ni Shicheng, and Hu Cheng.
Implants for Surgery - Active Implantable Medical
Devices - Part 7: Particular Requirements
for Cochlear Implant Systems
1 Scope
This Part of YY 0989 specifies requirements that are applicable to those active
implantable medical devices that are intended to treat hearing impairment via electrical
stimulation of the auditory pathways. Devices which treat hearing impairment via
means other than electrical stimulation are not covered by this Part.
The tests that are specified in this Part are type tests and are to be carried out on
samples of a device to show compliance.
This Part is also applicable to non-implantable parts and accessories of the devices
(see NOTE).
The electrical characteristics of the implantable part are determined by either the
appropriate method detailed in this Part or by any other method demonstrated to have
an accuracy equal to, or better than, the method specified. In the case of dispute, the
method detailed in this Part applies.
NOTE: A 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 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 part.
