15、rved vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whi

16、ch a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all m

17、atters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are cir

18、culated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies 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 respon

19、sible for identifying any or all such patent rights. ISO 14708-5 was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subcommittee SC 6, Active implants. ISO 14708 consists of the following parts, under the general title Implants for surgery Active implantable medical devices: Part

20、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 dev

21、ices intended to treat tachyarrhythmia (including implantable defibrillators) ISO 14708-5:2010(E) vi ISO 2010 All rights reservedIntroduction This part of ISO 14708 specifies requirements for safety and performance of active implantable circulatory support devices. It is not intended to be used for

22、extracorporeal perfusion devices, cardiomyoplasty, heart restraint devices, and counter-pulsation devices such as extra- or intra-aortic balloon pumps. It amends and supplements ISO 14708-1:2000, hereinafter referred to as ISO 14708-1. The requirements of this part of ISO 14708 take priority over th

23、ose of ISO 14708-1. Heart failure (HF) is a major public health problem. It is estimated that worldwide more than 5 million people die per year due to heart failure. The number of newly diagnosed cases is more than 550 000 per year in the USA alone (AHA 13 ). In 2001, nearly 53 000 patients in the U

24、nited States died of HF as a primary cause. Further, heart failure is implicated as a contributing factor in more than 250 000 deaths each year in the USA alone (Yusuf 29 ). Particularly at a higher risk for heart failure are the elderly ( 60 years), who account for 70 % of heart failure patients (H

25、aldeman et al 18 ), and for whom congestive heart failure is the leading cause of hospitalization. From 1990 to 1999, the annual number of hospitalizations has increased from approximately 810 000 to over 1 million for HF as a primary diagnosis and from 2,4 million to 3,6 million for HF as a primary

26、 or secondary diagnosis (Koelling TM et al, 30 ). The economic costs are enormous. It has been estimated that in 2005, the total direct and indirect cost of HF in the United States is equal to $27,9 billion (AHA 13 ). Worldwide, it is estimated that over $900 billion per year is spent and almost one

27、 third of patients are younger than 60. Heart transplantation in recent years has become an effective treatment for end-stage heart failure. Unfortunately the number of donor hearts is limited to just about 3 000 worldwide, available only to a small fraction of patients who need heart transplants. F

28、uture drug discoveries and/or biological therapies such as cell regeneration and gene therapy hold promise for the future in the treatment of chronic heart failure. However, as of today, mechanical circulatory devices remain the only alternative to heart transplantation and will continue to be a via

29、ble treatment for end-stage heart failure for the foreseeable future. Within this part of ISO 14708, the following terms are used to amend and supplement ISO 14708-1: “Replacement”: the clause of ISO 14708-1 is replaced completely by the text of this particular part of ISO 14708. “Addition”: the tex

30、t of this particular part is additional to the requirements of ISO 14708-1. “Amendment”: the clause of ISO 14708-1 is amended as indicated by the text of this particular part of ISO 14708. “Not used”: the clause of ISO 14708-1 is not applied in this particular part of ISO 14708. Subclauses, figures,

31、 or tables that are additional to those of ISO 14708-1 are numbered starting from 101; additional annexes are lettered AA, BB, etc. INTERNATIONAL STANDARD ISO 14708-5:2010(E) ISO 2010 All rights reserved 1Implants for surgery Active implantable medical devices Part 5: Circulatory support devices 1 S

32、cope This part of ISO 14708 specifies requirements for safety and performance of active implantable circulatory support devices. It is not applicable to extracorporeal perfusion devices, cardiomyoplasty, heart restraint devices and counter-pulsation devices, such as extra- or intra-aortic balloon pu

33、mps. This part of ISO 14708 specifies type tests, animal studies and clinical evaluation requirements. NOTE 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 combination of a device or devices and one or mor

34、e accessories. Not all of these parts are required to be either partially or totally implantable, but there is a need to specify main requirements of non- implantable parts and accessories if they could affect the safety or performance of the implantable device. 2 Normative references The following
