15、 bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental
16、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directiv
17、es, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
18、casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 27186 was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subco
19、mmittee SC 6, Active implants. BS ISO 27186:2010ISO 27186:2010(E) ISO 2010 All rights reserved vIntroduction The purpose of this International Standard is to specify a four-pole connector assembly to provide interchangeability between implantable leads and pulse generators for cardiac rhythm managem
20、ent from different manufacturers. The safety, reliability, biocompatibility, biostability and function of any particular part are the responsibility of the manufacturer. The four-pole connector was created to allow for a reduction in the number of individual lead connectors, reduce pocket bulk assoc
21、iated with existing bifurcated or trifurcated leads, reduce interaction of the lead bodies in the pocket and reduce set screw connections. This International Standard establishes two types of connector assembly: a “high voltage connector” and a “low voltage only connector”, each of which has several
22、 configurations. The high voltage connectors either have two low voltage contacts combined with one or two high voltage contacts, or they have only two high voltage contacts. The low voltage only connectors have either three or four low voltage contacts. The high voltage and low voltage only connect
23、ors and their voltage configurations are not intended to be interchangeable. This International Standard specifies a dimensional lockout feature that prevents the low voltage contacts of the lead connectors from contacting the high voltage contacts of high voltage connector cavities.

25、International Standard is not to be used if the implantable pulse generator is capable of introducing dangerous non-pacing stimuli (e.g. defibrillation shocks) through the contacts of that connector cavity. Likewise, the high voltage lead connector specified in this International Standard is not to
26、be used on leads intended for low voltage only therapy. 1 Scope This International Standard specifies a four-pole connector system for implantable cardiac rhythm management devices which have pacing, electrogram sensing and/or defibrillation functions. This International Standard includes requiremen
27、ts for the connector portion of an implantable lead as well as for the mating connector cavity attached to an implantable pulse generator. Essential dimensions and performance requirements are specified together with appropriate test methods. This International Standard is not intended to replace or
28、 provide alternatives for unipolar or bipolar connector standards that currently exist (such as ISO 11318 and ISO 5841-3). This International Standard is not applicable to high voltage systems with intended outputs greater than 1 000 V and/or 50 A. This International Standard is not applicable to sy
29、stems which include sensors or unique electrodes that are not capable of conventional pacing, electrogram sensing and/or defibrillation functions. This International Standard does not specify all connector features. It does not address all aspects of functional compatibility, safety or reliability o
30、f leads and pulse generators assembled into a system. NOTE Lead and pulse generator connector systems not conforming to this International Standard might be safe and reliable, and might have clinical advantages. 2 Normative references The following referenced documents are indispensable for the appl
