Cardiovascular implants - Endovascular devices - Part 2: Vascular stents (ISO 25539-2:2008)
ISO 25539-2:2008 specifies requirements for vascular stents, based upon current medical knowledge. With regard to safety, it gives requirements for intended performance, design attributes, materials, design evaluation, manufacturing, sterilization packaging and information supplied by the manufacturer. It should be considered as a supplement to ISO 14630, which specifies general requirements for the performance of non-active surgical implants.
The scope of ISO 25539-2:2008 includes vascular stents used to treat vascular lesions or stenoses, or other vascular abnormalities. These devices might or might not incorporate surface modifications of the stent such as drug and/or other coatings. Stents covered with materials that significantly modify the permeability of the uncovered stent are within the scope of ISO 25539-1:2003. The stent design might dictate the need to address functional requirements identified in both ISO 25539-1:2003 and ISO 25539-2:2008.
Delivery systems are included in ISO 25539-2:2008 if they comprise an integral component of the deployment of the vascular stent.
Some pharmacological aspects of drug eluting stents are addressed in ISO 25539-2:2008, but this document is not comprehensive with respect to the pharmacological evaluation of drug eluting stents.
With the exception of sterilization, ISO 25539-2:2008 does not address requirements for the evaluation of animal tissue products.
Kardiovaskuläre Implantate - Endovaskuläre Implantate - Teil 2: Gefäßstents (ISO 25539-2:2008)
1.1 Dieser Teil der ISO 25539 legt auf der Grundlage des derzeitigen medizinischen Wissensstandes
Anforderungen an Gefäßstents fest. Im Hinblick auf die Sicherheit enthält sie Anforderungen an die beabsichtigte
Funktion, Konstruktionsmerkmale, Werkstoffe/Materialien, die Bewertung der Konstruktion, die Herstellung,
die sterile Verpackung sowie die Bereitstellung von Informationen durch den Hersteller. Sie sollte als
Ergänzung zur ISO 14630 angesehen werden, die allgemeine Anforderungen an die Funktion nichtaktiver
chirurgischer Implantate festlegt.
ANMERKUNG Aufgrund der Variationen in der Konstruktion der von diesem Teil der ISO 25339 abgedeckten
Implantate sowie in einigen Fällen aufgrund der noch relativ neuen Entwicklung einiger dieser Implantate (z. B.
bioabsorbierbare Stents, Polymerstents) stehen nicht immer annehmbare genormte In-vitro-Prüfungen und klinische
Ergebnisse zur Verfügung. Mit dem Verfügbarwerden weiterer wissenschaftlicher und klinischer Daten wird eine
entsprechende Überarbeitung dieses Dokumentes erforderlich.
1.2 Der Anwendungsbereich dieses Teils von ISO 25539 schließt Gefäßstents ein, die zur Behandlung
vaskulärer Läsionen oder Stenosen oder sonstiger vaskulärer Anomalien eingesetzt werden. Bei diesen
Implantaten können Oberflächenmodifikationen des Stents, wie z. B. Medikamenten- und/oder weitere
Beschichtungen vorliegen. Stents, die mit Materialien ummantelt sind, die die Durchlässigkeit eines nicht
ummantelten Stents signifikant modifizieren, liegen im Anwendungsbereich der ISO 25539-1. Die Stentkonstruktion
kann die Anwendung funktionaler Anforderungen sowohl der ISO 25539-1 als auch dieses Teils
der ISO 25539 erforderlich machen.
1.3 Einführsysteme werden durch diesen Teil der ISO 25539 abgedeckt, sofern sie einen integralen
Bestandteil bei der Entfaltung des Gefäßstents darstellen.
1.4 Verfahren und Implantate, die vor der Einführung des Gefäßstents verwendet wurden, wie z. B. durch
Ballonangioplastie eingebrachte
Implants cardiovasculaires - Dispositifs endovasculaires - Partie 2: Stents vasculaires (ISO 25539-2:2008)
L'ISO 25539-2:2008 spécifie les exigences relatives aux stents vasculaires selon les connaissances médicales actuelles. En ce qui concerne la sécurité, elle donne les exigences relatives aux performances attendues, aux caractéristiques de conception, aux matériaux, à l'évaluation de la conception, à la fabrication, à la stérilisation, à l'emballage et aux informations fournies par le fabricant. Il convient de la considérer comme un complément à l'ISO 14630 qui spécifie les exigences générales relatives aux performances des implants chirurgicaux non actifs.
Le domaine d'application de l'ISO 25539-2:2008 inclut les stents utilisés dans le traitement des lésions vasculaires ou sténoses, ou d'autres anomalies vasculaires. Ces dispositifs peuvent comprendre ou non, des modifications de surface du stent telles qu'un revêtement renfermant ou non un médicament. Les stents recouverts de matériaux qui modifient sensiblement l'étanchéité du stent nu sont compris dans le domaine d'application de l'ISO 25539-1:2003. La conception des stents peut rendre nécessaire d'analyser les exigences fonctionnelles identifiées à la fois dans l'ISO 25539-1:2003 et dans l'ISO 25539-2:2008.
Les systèmes d'injection sont inclus dans l'ISO 25539-2:2008 s'ils comprennent un composant intégral du déploiement du stent vasculaire.
Certains aspects pharmacologiques des stents à élution de médicaments sont traités dans l'ISO 25539-2:2008, mais celle-ci ne détaille pas l'évaluation pharmacologique de ce type de stent.
À l'exception de la stérilisation, l'ISO 25539-2:2008 ne traite pas les exigences relatives à l'évaluation des produits de tissus animaux.
