ISO 14708-4:2022

Overview - ISO 14708-4:2022 (Implantable infusion pump systems)

ISO 14708-4:2022 is the international standard that specifies particular requirements for active implantable medical devices intended to deliver medicinal substances to site‑specific locations in the human body - commonly known as implantable infusion pump systems. This Part 4 document amends and supplements ISO 14708-1:2014 and takes precedence where requirements differ. It is focused on safety and provides type test requirements (for sample testing to demonstrate compliance), not routine production testing. The standard also applies to certain non‑implantable parts and accessories (e.g., external programmers, refill kits) but does not cover non‑implantable infusion systems.

Key technical topics and requirements

The standard organizes device requirements across functional, mechanical, electrical and informational domains. Key topics include:

• Device definition and scope - terms such as bolus, fluid pathway, catheter access port, infusion rate accuracy, maximum/minimum infusion rate.
• General safety & risk management - supplements ISO 14708‑1 with device‑specific hazards and mitigations.
• Software & usability - requirements for non‑implantable parts and user interfaces (programmability, usability).
• Packaging, markings and labelling - sales and sterile pack marking, construction and information for safe handling and implantation.
• Mechanical and material integrity - septum puncture tests, protection from mechanical forces, temperature and pressure changes.
• Electrical & electromagnetic protection - electrical safety, protection from defibrillators, electrostatic discharge (ESD), and EMC testing (including radiated immunity).
• Magnetic resonance and RF considerations - MRI safety guidance (ISO/TS 10974 referenced), static magnetic fields up to 50 mT, magnetic fields 16 Hz–26 MHz, and EM disturbances 80 MHz–2.7 GHz.
• Biocompatibility & unintended effects - prevention of unintentional biological effects from the implant and the fluid pathway.
• Documentation & testing - required accompanying documentation, type test methods and optional characterization testing.

Practical applications and who uses this standard

ISO 14708-4:2022 is intended for:

• Medical device manufacturers designing and validating implantable infusion pumps and associated accessories.
• Design engineers and R&D teams developing infusion mechanisms, catheters and refill systems.
• Quality, regulatory and compliance professionals preparing technical files, CE/510(k)/MDR submissions and conformity assessments.
• Test laboratories and notified bodies performing type testing for safety, EMC and MRI compatibility demonstrations.
• Clinicians and hospital procurement teams evaluating device safety, labeling and usability.
