Full title and description

St ASTM F2081-06 (2022) — Standard Guide for Characterization and Presentation of the Dimensional Attributes of Vascular Stents. This guide defines recommended dimensional attributes, measurement methods, and presentation formats for vascular stents and their packaged delivery systems to support consistent labeling, testing, and clinical decision-making.

Abstract

Provides a concise set of dimensional attributes (for example: labeled and deployed diameters, deployed length and shortening/lengthening, crossing profile, wall thickness, strut geometry and crimped profile), recommended measurement methods (noncontact instruments, calibrated gauges, standardized preconditioning and test environments), and guidance on units and presentation of results. Intended to make stent dimensional data comparable across manufacturers and useful to clinicians, test laboratories, and regulators.

Scope

This guide covers identification of, and recommended measurement methods for, the dimensional attributes of vascular stents that are considered relevant to clinical performance. The scope explicitly includes the delivery system packaged and labeled for placement of the stent. The guide addresses units (SI or inch‑pound used independently), recommended test environments (for example, temperature and fluid immersion where appropriate), and presentation of dimensional data for labeling and technical reports.

Key topics and requirements

• List of dimensional attributes to report: labeled diameter, deployed (inside/outside) diameter, deployed length, undeployed length, shortening/lengthening (percentage), wall thickness, strut dimensions, crossing profile, and crimped profile.
• Measurement methods: use of noncontact instruments (optical profilometers, laser micrometers), calibrated gauges, ring/hole gages and specified resolution limits (examples cited in the guide).
• Sampling and replication: recommendations for a minimum number of replicate test articles for reporting representative values.
• Test environment and preconditioning: guidance on immersion, temperature control (e.g., 37 ± 2 °C where deployment/measurement is environment‑sensitive) and equilibration for measurements affected by fluid/temperature.
• Units and reporting: SI and inch‑pound systems are treated separately and should not be combined; labeled diameter and presentation conventions are defined for clarity in labeling and technical documentation.
• Presentation and labeling: recommended formats for reporting measured values and tolerances so clinicians and regulatory reviewers can compare devices.

Typical use and users

Primary users are vascular stent manufacturers, product development and quality laboratories, regulatory submissions teams, test laboratories, and researchers. Clinical engineers and interventional physicians may use the standardized dimensional data for device selection and comparative assessment. Regulatory authorities and notified bodies use the guide as a reference for consistent presentation of dimensional attributes in submissions and reviews.

Related standards

Commonly referenced alongside this guide are ISO 25539‑2 (endovascular devices — vascular stents), ASTM test methods and guides for stent performance (examples include F2079 for intrinsic elastic recoil, F2477 for in vitro pulsatile durability, F2394 for securement of balloon‑expandable stents mounted on delivery systems, and more recent ASTM F-series items addressing coating, durability, and particulate testing), and relevant FDA guidance on non‑clinical testing and labeling of intravascular stents.
