Abstract

Es wird ein Verfahren und eine Vorrichtung zur Bestimmung einer Oberflächencharakteristik eines Stents zur Implantation in ein Körperlumen vorgesehen, bei dem ein Benetzungsverhalten einer Stentoberfläche als Mass für die Oberflächencharakteristik der Stentoberfläche dient. Zur Ermittlung des Benetzungsverhaltens wird ein Verlauf einer Benetzungskraft entlang einer Länge der Stentoberfläche bestimmt, wobei die zwischen der Stentoberfläche und einer Flüssigkeitsoberfläche anliegende Benetzungskraft entlang der Stentlänge erfasst wird.
