ISO 5910:2018 pdf free download.Cardiovascular implants and extracorporeal systems – Cardiac valve repair devices.
No heart valve repair device is ideal. Therefore, a group of engineers, scientists, and clinicians, experts well aware of the problems associated with heart valve repair devices and their development, has prepared this document. ISO 5910 specifies types of tests, test methods, and requirements for test apparatus. It requires documentation of test methods and results. ISO 5910 deals with those areas that will ensure adequate mitigation of device-associated risks for patients and other users of the device, facilitate quality assurance, aid the heart team in choosing a heart valve repair device, and ensure that the device will be provided in a convenient and usable form. ISO 5910 emphasizes the need to specify and report types of in vitro testing. preclinical in vivo and clinical evaluations. It describes the labels and packaging of the device. Such a process involving in vitro, preclinical in vivo and clinical evaluations is intended to clarify the requirements prior to market release and to enable prompt identification and management of any subsequent problems.
With regard to in vitro testing and reporting, apart from basic material testing for mechanical, physical. chemical and biocompatibility characteristics, ISO 5910 also covers important functional and durability characteristics of heart valve repair devices and their accessories. ISO 5910 does not specify exact test methods for functional and durability testing but it offers guidelines for the test apparatus.
ISO 5910 should be revised, updated, and amended as knowledge and techniques in heart valve repair device technology improve.
1.1 ISO 5910 applies to all heart valve repair systems that have an intended use to repair and/ or improve the function of native human heart valves by acting either on the valve apparatus or on the adjacent anatomy (e.g. ventricle, coronary Sinus).
1.2 ISO 5910 outlines an approach for verifying/validating the design and manufacture of a heart valve repair system through risk management. The selection of appropriate verification/validation tests and methods are derived from the risk assessment. The tests include assessments of the physical. chemical, biological, and mechanical properties of components and materials of heart valve repair systems. The tests also include preclinical in vivo evaluation and clinical investigation of the finished heart valve repair system to assess the safety and effectiveness of the heart valve repair system.
NOTE For the purposes of ISO 5910, effectiveness endpoint includes clinical performance and benefits.
1.3 ISO 5910 defines operational conditions and performance requirements for heart valve repair systems where adequate scientific and/or clinical evidence exists for their justification.
1.4 ISO 5910 excludes Cardiac Resynchronization Therapy (CRT) devices, paravalvular leakage closure devices, systems that do not leave an implant in place (e.g. ablation, radio frequency annuloplasty), apical conduits and devices with components containing viable cells. ISO 5910 also excludes materials not intended for repairing and/or improving the function of human heart valves according to its intended use (e.g. patch material and sutures used in general surgical practice).
NOTE A rationale for the provisions of this document is given in Annex A.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain termlnological databases for use In standardization at the Following addresses
6.2.5 Packaging, labelling, and sterilization
The heart valve repair system shall meet the requirements for packaging, labelling, and sterilization contained within Annex C. Annex 1). and Annex E, respectively.
6.3 Design outputs
The manufacturer shall establish (I.e. define, document, and implement) a complete speclllcatlon of the heart valve repair system, including component and assembly-level specifications, delivery system, accessories, packaging, and labelling. contains examples of various heart valve repair devices and Annex F contains descriptive characteristics for heart valve repair systems. In addition to the physical components olthe heart valve repair system, the Implant procedure itself should be considered an important element of safe and effective heart valvc repair therapy.
