Cardiovascular implants - Endovascular devices - Part 2: Vascular stents (ISO 25539-2:2008)

This part of ISO 25539 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 this part of ISO 25539 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. The stent design might dictate the need to address functional requirements identified in both ISO 25539-1 and this part of ISO 25539. Delivery systems are included in this part of ISO 25539 if they comprise an integral component of the deployment of the vascular stent. Procedures and devices used prior to the introduction of the vascular stent, such as balloon angioplasty devices, are excluded from the scope of this part of ISO 25539. Some pharmacological aspects of drug eluting stents are addressed in this part of ISO 25539, but this document is not comprehensive with respect to the pharmacological evaluation of drug eluting stents. Degradation and other time-dependent aspects of bioabsorbable and polymeric stents and coatings are not addressed by this part of ISO 25539. With the exception of sterilization, this part of ISO 25539 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 Anfor¬de¬rungen an Gefäßstents fest. Im Hinblick auf die Sicherheit enthält sie Anforderungen an die beabsich¬tigte Funktion, Konstruktionsmerkmale, Werkstoffe/Materialien, die Bewertung der Konstruktion, die Her¬stellung, 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 vasku¬lärer Läsionen oder Stenosen oder sonstiger vaskulärer Anomalien eingesetzt werden. Bei diesen Implantaten können Oberflächenmodifikationen des Stents, wie z. B. Medikamenten  und/oder weitere Beschich¬tungen vorliegen. Stents, die mit Materialien ummantelt sind, die die Durchlässigkeit eines nicht ummantelten Stents signifikant modifizieren, liegen im Anwendungsbereich der ISO 25539 1. Die Stent-konstruktion 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.
