Overview
EN ISO 14708-3:2022 (ISO 14708-3:2017) specifies particular safety and performance requirements for implantable neurostimulators - active implantable medical devices intended to deliver electrical stimulation to the central or peripheral nervous system. It amends and supplements ISO 14708-1 and takes precedence where clauses differ. The standard focuses on type testing of device samples to assess behavioural responses; these tests are not intended for routine production testing.
Key topics and technical requirements
This part of the ISO 14708 series addresses a range of device, packaging and safety topics relevant to implantable neurostimulators, including:
- Scope and definitions specific to neurostimulation therapies and device architectures (pulse generators, leads, extensions, programmers).
- Type testing requirements - tests performed on representative samples to evaluate device behaviour under specified conditions.
- Marking and labelling requirements for devices, sterile packs and sales packaging to ensure traceability and safe use.
- Packaging and sterile pack construction to protect implantable devices until use.
- Electrical safety and protection against harm from electricity, including effects of external electrical fields and electrostatic discharge.
- Electromagnetic compatibility (EMC) considerations and test protocols relevant to implantable devices (see also ISO 14117).
- Protection from mechanical, thermal and atmospheric stresses, including temperature and pressure changes during handling and transport.
- Protection from ionizing and non‑ionizing radiation, and from external medical interventions such as defibrillators or other treatments that could affect device function.
- Software, programmers and accessories: requirements cover parts that might not be implantable but could affect safety or performance.
- Documentation and labelling requirements for accompanying information and user guidance.
Practical applications and who uses this standard
SIST EN ISO 14708-3 is used by stakeholders involved in the design, manufacture, testing and regulation of implantable neurostimulators:
- Medical device manufacturers - to design devices and prepare technical files demonstrating compliance.
- Design and test engineers - to define type-test programs and validate device robustness, EMC and electrical safety.
- Quality, regulatory and compliance teams - to support CE marking and national regulatory submissions in markets adopting EN ISO texts.
- Notified bodies and testing laboratories - to assess conformity and perform required type tests.
- Procurement and clinical engineering - to verify device labelling, packaging and safety information.
