GB/T 44138-2024 Cardiovascular implants—Cardiovascular absorbable implants
Basic Information
Scope
This document specifies the general principles and requirements for the design evaluation of absorbable cardiovascular implants used to treat blood vessels and/or vascular regions (including the heart and the entire circulatory system). This document can be used as a supplement to specific device standards. This document applies to implants that come into direct contact with the cardiovascular system and are intended to function in the circulatory system. Note 1: Certain aspects of the absorbable components of cardiovascular drug-device combination products (such as coatings) are related to the content of the drug and are described in GB/T 39381.1. Note 2: The interpretation of absorbable, degradable, and related terms is provided in Appendix A. Note 3: This document does not specifically evaluate issues related to living tissues, living cells, and/or implants containing non-living biological materials and their derivatives. Additionally, procedures and devices used before and after the implantation of cardiovascular absorbable implants (such as balloon angioplasty devices) are not within the scope of this document if they do not affect the absorption of the implants. Absorbable cardiovascular implants may contain substances that can be considered pharmaceutical products (drugs) when used alone, but the drug effect is auxiliary to the implant and supports the main mode of action of the implant.
