YY/T 1787-2021 Cardiovascular implants—Cardiac valve repair devices and delivery system
Basic Information
Scope
This standard specifies the operating conditions and performance requirements for heart valve repair devices and their delivery systems (if applicable).
This standard applies to all heart valve repair devices (e.g., valvuloplasty devices, leaflet clamping devices, artificial chordae, etc.) intended to act on the valve structure or adjacent anatomical structures (e.g., ventricles, coronary sinus) to repair and/or improve the function of human native heart valves.
This standard does not apply to cardiac resynchronization therapy (CRT) devices, perivalvular leak closure devices, non-implantable systems (e.g., ablation, radiofrequency valvuloplasty), apical catheters and devices with living cell components. The standard also does not apply to materials intended for purposes other than repairing and/or improving the function of human heart valves (e.g., patch materials and sutures for general surgery).
Note 1: YY/T 0640 specifies the general requirements for the performance of passive surgical implants, and this standard can be regarded as a supplement to YY/T 0640.
Note 2: This standard outlines the methods of verifying/confirming the design and manufacturing of heart valve repair systems through risk management. Appropriate verification/confirmation tests and methods are selected through risk assessment. Such tests include the evaluation of the physical, chemical, biological, and mechanical properties of the components and materials of the heart valve repair system. The tests also include preclinical in vivo evaluations of finished heart valve repair systems to assess the safety and effectiveness of the heart valve repair system.
Note 3: Appendix A provides the basic principles of the provisions of this standard.
