Cardiovascular implants - Cardiac valve prostheses - Part 1: General requirements (ISO 5840-1:2021)
This document is applicable to heart valve substitutes intended for implantation and provides general requirements. Subsequent parts of the ISO 5840 series provide specific requirements.
This document is applicable to newly developed and modified heart valve substitutes and to the accessory devices, packaging, and labelling required for their implantation and for determining the appropriate size of the heart valve substitute to be implanted.
ISO 5840-1 outlines an approach for verifying/validating the design and manufacture of a heart valve substitute through risk management. The selection of appropriate qualification tests and methods are derived from the risk assessment. The tests can include those to assess the physical, chemical, biological, and mechanical properties of heart valve substitutes and of their materials and components. The tests can also include those for preclinical in vivo evaluation and clinical evaluation of the finished heart valve substitute.
ISO 5840-1 defines operational conditions for heart valve substitutes.
ISO 5840-1 furthermore defines terms that are also applicable to ISO 5840-2 and ISO 5840-3.
ISO 5840-1 does not provide requirements specific to homografts, tissue engineered heart valves (e.g. valves intended to regenerate in vivo), and heart valve substitutes designed for implantation in circulatory support devices. Some of the provisions of ISO 5840-1 can be applied to valves made from human tissue that is rendered non-viable.
NOTE A rationale for the provisions of ISO 5840-1 is given in Annex A.
Herz- und Gefäßimplantate - Herzklappenprothesen - Teil 1: Allgemeine Anforderungen (ISO 5840-1:2021)
Dieses Dokument ist auf Herzklappenersatz anwendbar, der für die Implantation in den Körper vorgesehen ist, und enthält allgemeine Anforderungen. Spezifische Anforderungen werden in den anderen Teilen der Normenreihe ISO 5840 festgelegt.
Dieses Dokument gilt für neu entwickelten und veränderten Herzklappenersatz; die Zubehörteile, Verpackung und Kennzeichnung, die für die Implantation erforderlich sind; und die Bestimmung der geeigneten Größe des zu implantierenden Herzklappenersatzes.
ISO 5840-1 umreißt eine Herangehensweise zur Überprüfung/Validierung des Designs und der Herstellung eines Herzklappenersatzes auf der Grundlage des Risikomanagements. Die Auswahl der geeigneten Qualifi¬kationsprüfungen und verfahren leitet sich aus der Risikobeurteilung ab. Zu diesen Prüfungen können solche zur Beurteilung der physikalischen, chemischen, biologischen und mechanischen Eigenschaften eines Herzklappenersatzes und von dessen Werkstoffen und Bauteilen gehören. Diese Prüfungen können auch die vorklinische In vivo und die klinische Bewertung des fertigen Herzklappenersatzes einschließen.
ISO 5840-1 legt Betriebsbedingungen für Herzklappenersatz fest.
ISO 5840 1 definiert darüber hinaus Begriffe, die auch für ISO 5840 2 und ISO 5840 3 gelten.
ISO 5840-1 stellt keine Anforderungen, die für Homografte, gewebetechnologisch hergestellte Herzklappen (z. B. Herzklappen, die In vivo regenerieren sollen) und Herzklappenersatz, der für die Implantation in Kreislaufunterstützungssystemen ausgelegt ist, spezifisch sind. Einige der Regelungen von ISO 5840-1 können auf aus abgetötetem menschlichen Gewebe hergestellten Klappen angewendet werden.
ANMERKUNG Eine Begründung für die Festlegungen von ISO 5840-1 wird in Anhang A gegeben.
Implants cardiovasculaires - Prothèses valvulaires - Partie 1: Exigences générales (ISO 5840-1:2021)
Le présent document s'applique aux prothèses valvulaires destinées à une implantation chez l'homme et établit des exigences générales. Les exigences spécifiques figurent dans les parties qui succèdent à la présente partie de l'ISO 5840.
Le présent document s'applique aux prothèses valvulaires récemment mises au point et aux prothèses valvulaires modifiées, ainsi qu'aux dispositifs auxiliaires, à l'emballage et à l'étiquetage exigés pour leur implantation. Il s'applique également à la détermination de la taille appropriée de la prothèse valvulaire à implanter.
L'ISO 5840-1 présente une approche pour la vérification/validation de la conception et la fabrication d'une prothèse valvulaire à travers la gestion des risques. La sélection des méthodes et des essais de qualification appropriés se fait à partir de l'appréciation du risque. Des essais peuvent être destinés à évaluer les propriétés physiques, chimiques, biologiques et mécaniques de prothèses valvulaires ainsi que celles de leurs matériaux et composants. Les essais peuvent également englober les essais destinés à l'évaluation préclinique in vivo et à l'évaluation clinique des prothèses valvulaires à l'état fini.
L'ISO 5840-1 définit les conditions de fonctionnement des prothèses valvulaires.
En outre, l'ISO 5840-1 définit les termes qui sont aussi applicable à l'ISO 5840-2 et l'ISO 5840-3.
L'ISO 5840-1 ne contient pas d'exigences spécifiques aux homogreffes, aux valves cardiaques issues de l'ingénierie tissulaire (par exemple, valves conçues pour se régénérer in vivo), ni aux prothèses valvulaires conçues pour une implantation dans des dispositifs d'assistance circulatoire. Certaines dispositions de l'ISO 5840-1 peuvent s'appliquer à des valves réalisées à partir de tissus humains rendus non viables.
NOTE Une justification des dispositions de l'ISO 5840-1 est donnée à l'Annexe A.
