Abstract: A system and method for loading a self-expandable prosthetic device into a delivery device. The system includes a compression member that has a chamber with a tapered inner surface, a support member, a splay member and a constriction member. The compression member and the constriction member can be releasably attached to each other directly or via a spacer element, in two different positions relative to each other. The first position offers an optimal configuration for releasable attachment of the prosthetic device to the delivery device and the second position offers an optimal configuration for reducing the diameter of the delivery device. The risk of damaging the delivery device and to the prosthetic device during the loading procedure is thereby reduced.

Abstract: In the case of a method for absolute calibration of an interferometer with the aid of a spherical output wave, comprising an optical element which retroflects the incident spherical wave itself or via a mirror, at least four measuring procedures are undertaken to determine a wave aberration W. The optical element is measured in the at least four measuring positions intrafocally and extrafocally in at least two different rotational angle positions. It is also possible, in addition, to undertake a measurement via a mirror in the cat's eye position (focus 3).
