YY/T 1747-2021 Neurovascular implants—Intracranial artery stents
Basic Information
Scope
This standard specifies the general requirements, expected performance, design attributes, materials, laboratory design evaluation, post-market supervision, manufacturing, sterilization, and packaging for intracranial arterial stents.
This standard applies to stent-type products used in intracranial arteries to treat bleeding or ischemic symptoms, including stents and the delivery systems used with them. This standard does not include devices used to deliver stents (such as microcatheters) and other ancillary devices.
This standard does not apply to intracranial arterial aneurysm blood flow guidance devices.
This standard does not include bioresorbable stents, polymer stents, the degradation of stent coatings, or other time-dependent aspects.
This standard does not include procedures and devices used prior to the implantation of intracranial arterial stents.
