YY/T 1748-2021 Neurovascular implants—Intracranial embolization coils
Basic Information
Scope
This standard specifies the general requirements, design attributes, and laboratory design evaluation for spring coils, push rods, and spring coil systems. This standard applies to spring coil products used in the treatment of intracranial aneurysms, arteriovenous fistulas, arteriovenous malformations, and other intracranial vascular lesions, as well as the push rods and introducer sheaths that accompany them.
This standard does not apply to spring coil products used in the treatment of other vascular aneurysms.
Note 1: Spring coil products used for other vascular aneurysms can refer to this standard for implementation.
This standard does not apply to devices assisting in spring coil release (referred to as release devices, such as separation control boxes, etc.).
Note 2: Release devices must comply with relevant standards or technical requirements. Release devices may be used as auxiliary devices in the design evaluation of spring coils.
This standard does not involve content related to drugs.
Note 3: For drug components included in product design, they shall comply with corresponding laws, regulations, and other documents.
Note 4: YY/T 0640 specifies the general requirements for the performance of passive surgical implants. This standard can be used as a supplement to YY/T 0640.
