ISO 5840-2:2015 Preview
Cardiovascular implants -- Cardiac valve prostheses -- Part 2: Surgically implanted heart valve substitutes
ISO 5840-2:2015 is applicable to heart valve substitutes intended for implantation in human hearts, generally requiring cardiopulmonary bypass and generally with direct visualization.
ISO 5840-2:2015 is applicable to both newly developed and modified surgical heart valve substitutes and to the accessories, packaging, and labelling required for their implantation and for determining the appropriate size of the surgical heart valve substitute to be implanted.
ISO 5840-2:2015 outlines an approach for qualifying the design and manufacture of a surgical 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 mechanical properties of surgical heart valve substitutes and of their materials and components. The tests may also include those for pre-clinical in vivo evaluation and clinical evaluation of the finished surgical heart valve substitute.
ISO 5840-2:2015 defines performance requirements for surgical heart valve substitutes where adequate scientific and/or clinical evidence exists for their justification.
For novel surgical heart valve substitutes, e.g. sutureless, the requirements of both this International Standard and ISO 5840‑3 might be relevant and shall be considered as applicable to the specific device design and shall be based on the results of the risk analysis.
ISO 5840-2:2015 excludes heart valve substitutes designed for implantation in artificial hearts or heart assist devices.
ISO 5840-2:2015 excludes homografts.
