43、titutes with emphasis on specifying types of in vitro testing, preclinical in vivo and clinical evaluations, reporting of all in vitro, preclinical in vivo, and clinical evaluations and labelling and packaging of the device. This process is intended to clarify the required procedures prior to market

44、 release and to enable prompt identification and management of any subsequent issues.This part of ISO 5840 is to be used in conjunction with ISO 5840-1.DIN EN ISO 5840-2:2016-05 EN ISO 5840-2:2015 (E) 6 1 ScopeThis part of ISO 5840 is applicable to heart valve substitutes intended for implantation i

45、n human hearts, generally requiring cardiopulmonary bypass and generally with direct visualization.This part of ISO 5840 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 determ

46、ining the appropriate size of the surgical heart valve substitute to be implanted.This part of ISO 5840 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 derive

47、d 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 t

48、he finished surgical heart valve substitute.This part of ISO 5840 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.This part of ISO 584
