Overview
EN ISO 10555-4:2023 - “Intravascular catheters - Sterile and single‑use catheters - Part 4: Balloon dilatation catheters” specifies essential requirements and test methods for sterile, single‑use balloon dilatation catheters. Endorsed by CEN in November 2023 and published as ISO 10555-4:2023, this part of the ISO 10555 series replaces the 2013 edition and focuses on performance, safety and labelling specific to balloon catheters used to dilate vascular lesions. Annex G provides guidance on balloon material selection.
Key topics and technical requirements
- Scope and definitions
- Defines a balloon dilatation catheter, balloon rated burst pressure (RBP), crossing profile and effective balloon length.
- Designations and labelling
- Required nominal size details: inflated balloon diameter, effective balloon length, maximum compatible guidewire diameter and minimum inner diameter of introducer/guide/sheath.
- Detectability
- Balloon position must be detectable by X‑ray or other imaging (ultrasound, MRI); test methods such as ASTM F640-20 or DIN 13273-7 are referenced.
- Physical performance tests (normative annexes)
- RBP (Annex A): Determine balloon rated burst pressure.
- Fatigue/leakage (Annex B): Verify freedom from leakage or damage after repeated inflation cycles (default 10 cycles or a clinically justified alternative).
- Deflation time (Annex C): Measure time to deflate from RBP.
- Balloon compliance (Annex D): Relationship between balloon diameter and inflation pressure.
- Crossing profile (Annex E): Measure maximum outer diameter between proximal balloon bond and distal tip.
- Balloon removal (Annex F): Demonstrate safe removal after inflation/deflation without damage.
- Information to be supplied
- Conforms with ISO 10555-1 requirements plus the additional balloon‑specific data above.
Practical applications and who uses the standard
- Medical device manufacturers use EN ISO 10555-4:2023 to design, validate and document balloon dilatation catheters for regulatory submissions and CE marking.
- Quality, R&D and regulatory teams use the test methods for bench validation and risk assessments.
- Clinical engineers, procurement and hospitals rely on standardized labelling and performance claims to select compatible introducers, guidewires and delivery systems.
- Notified bodies and regulators use the standard as a reference for conformity assessment of sterile single‑use balloon catheters.
Related standards
- ISO 10555-1:2023 - General requirements for sterile single‑use intravascular catheters
- ISO 25539-2 - Vascular stent systems (not covered by this document)
- Test references: ASTM F640-20, DIN 13273-7
EN ISO 10555-4:2023 is a practical, test‑focused standard that helps ensure the safety, compatibility and documented performance of balloon dilatation catheters across design, manufacturing and clinical use.
