Apparatus and method for checking the fatigue strength of a vascular graft

摘要

The apparatus (1) for checking the fatigue strength of at least one vascular graft (2) with at least two fixing devices (3, 4) at the end cross-sections of the vascular graft (2), at least two drives, which, with the fixing devices (3, 4) are coupled together and by the different types of stress, which form a testing regime, on the vascular graft (2) and can be applied with at least one vascular graft (2), wherein the apparatus (1) at least one guide element (10), on which the vascular graft (2) is possible and, by its rotational movement of a mold change kinematics of the vascular graft (2) at a specific application site is imitated, characterised in that the guide element (10) at least one circular and / or involutes 7d of conveying, the spatial path curve (11) or partial segments of a curved path (11) for generating a travel controlled a - or biaxial rotation bending of the vascular graft (2) comprises.
