The work of preparing International Standards is normall
27、y 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 and non-governmental, in liaison with ISO, also take part in the
28、work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the di
29、fferent approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document
30、may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/pat

33、ith ISO 5840-2 and ISO 5840-3, cancels and replaces ISO 5840:2005, which has been technically revised.ISO 5840 consists of the following parts, under the general title Cardiovascular implants Cardiac valve prostheses: Part 1: General requirements Part 2: Surgically implanted heart valve substitutes
34、Part 3: Heart valve substitutes implanted by transcatheter techniquesiv ISO 2015 All rights reservedBS EN ISO 5840-1:2015ISO 5840-1:2015(E)IntroductionThere is, as yet, no heart valve substitute which can be regarded as ideal.The ISO 5840series has been prepared by a group well aware of the issues a
35、ssociated with heart valve substitutes and their development. In several areas, the provisions of the ISO 5840series deliberately have not been specified to encourage development and innovation. It does specify the types of tests, test methods, and/or requirements for test apparatus and requires doc
36、umentation of test methods and results. The areas with which the ISO 5840series are concerned are those which will ensure that associated risks to the patient and other users of the device have been adequately mitigated, facilitate quality assurance, aid the clinician in choosing a heart valve subst
37、itute, and ensure that the device will be presented at the operating table in convenient form. Emphasis has been placed on specifying types of in vitro testing, on preclinical in vivo and clinical evaluations, on reporting of all in vitro, preclinical in vivo, and clinical evaluations, and on the la
38、belling and packaging of the device. Such a process involving in vitro, preclinical in vivo, and clinical evaluations is intended to clarify the required procedures prior to market release and to enable prompt identification and management of any subsequent problems.With regard to in vitro testing a
39、nd reporting, apart from basic material testing for mechanical, physical, chemical, and biocompatibility characteristics, the ISO 5840series also covers important hydrodynamic and durability characteristics of heart valve substitutes. The ISO 5840series does not specify exact test methods for hydrod
40、ynamic and durability testing, but it offers guidelines for the test apparatus.The ISO 5840series is incomplete in several areas. It is intended to be revised, updated, and/or amended as knowledge and techniques in heart valve substitute technology improve. ISO 2015 All rights reserved vBS EN ISO 58
41、40-1:2015BS EN ISO 5840-1:2015Cardiovascular implants Cardiac valve prostheses Part 1: General requirements1 ScopeThis part of ISO 5840 is applicable to heart valve substitutes intended for human implantation and provides general requirements. Subsequent parts of the ISO 5840series provide specific
42、requirements.This part of ISO 5840 is applicable to both newly developed and modified heart valve substitutes and to the accessories, packaging, and labelling required for their implantation and for determining the appropriate size of the heart valve substitute to be implanted.This part of ISO 5840
43、outlines an approach for qualifying the design and manufacture of a heart valve substitute through risk management. The selection of appropriate qualification tests and methods are derived from the risk assessment. The tests may include those to assess the physical, chemical, biological, and mechani
44、cal properties of heart valve substitutes and of their materials and components. The tests may also include those for preclinical in vivo evaluation and clinical evaluation of the finished heart valve substitute.This part of ISO 5840 defines operational conditions for heart valve substitutes.This pa
