31、order to provide minimum requirements for endovascular devices and the methods of test that will enable their evaluation. It is the second part of a three-part standard. ISO 25539-1 addresses endovascular prostheses and ISO 25539-3 addresses vena cava filters. ISO/TS 15539, from which this part of I
32、SO 25539 is derived, serves as a rationale for the requirements of this part of ISO 25539. The Technical Specification ISO/TS 15539 was developed by first identifying the design requirements for these devices and listing the potential device and clinical failure modes. Tests were then identified to
33、address each of the failure modes. The requirements provided in this part of ISO 25539 are based on that assessment.

34、permitted without license from IHS-,-,-Cardiovascular implants Endovascular devices Part 2: Vascular stents1 Scope1.1 This part of ISO 25539 specifies requirements for vascular stents, based upon current medical knowledge. With regard to safety, it gives requirements for intended performance, design
35、 attributes, materials, design evaluation, manufacturing, sterilization, packaging and information supplied by the manufacturer. It should be considered as a supplement to ISO 14630, which specifies general requirements for the performance of non-active surgical implants.NOTE Due to the variations i
36、n the design of implants covered by this part of ISO 25539 and in some cases due to the relatively recent development of some of these implants (e.g. bioabsorbable stents, polymeric stents), acceptable standardized in vitro tests and clinical results are not always available. As further scientific a
37、nd clinical data become available, appropriate revision of this part of ISO 25539 will be necessary.1.2 The scope of this part of ISO 25539 includes vascular stents used to treat vascular lesions or stenoses, or other vascular abnormalities. These devices might or might not incorporate surface modif
38、ications of the stent such as drug and/or other coatings. Stents covered with materials that significantly modify the permeability of the uncovered stent are within the scope of ISO 25539-1. The stent design might dictate the need to address functional requirements identified in both ISO 25539-1 and
39、 this part of ISO 25539.1.3 Delivery systems are included in this part of ISO 25539 if they comprise an integral component of the deployment of the vascular stent.1.4 Procedures and devices used prior to the introduction of the vascular stent, such as balloon angioplasty devices, are excluded from t
40、he scope of this part of ISO 25539.1.5 Some pharmacological aspects of drug-eluting stents are addressed in this part of ISO 25539, but this part of ISO 25539 is not comprehensive with respect to the pharmacological evaluation of drug-eluting stents.1.6 Degradation and other time-dependent aspects o
41、f bioabsorbable and polymeric stents and coatings are not addressed by this part of ISO 25539.1.7 With the exception of sterilization, this part of ISO 25539 does not address requirements for the evaluation of animal tissue products.2 Normative referencesThe following referenced documents are indisp
