    摘要： The present invention relates to an implant, in particular an intraluminal endoprothesis, comprising a body containing a metallic material, and comprising at least one functional element that is fastened to the body and has a material composition in at least a portion of its volume that differs from the material of the body, the material composition preferably including radio-opaque and/or x-ray opaque material. To effectively prevent accelerated degradation due to the formation of a local cell of the material of the body and the functional element, the at least one functional element includes a first layer at least in the region of its surface where it is bonded to the body, the first layer primarily containing at least one metal oxide. Furthermore, the manufacture of an implant of this type is described.

    摘要： The device for measuring the internal diameter of tubes 2 consisting of two interconnected measuring units 3 and 4 that are connected to one another. The first measuring unit 3 is formed by a measuring head 9 in conjunction with a displacement transducer 7, which is axially displaceable within a tube 2. The axial displacement of the measuring head 9 is determined by a length measuring device consisting of a friction wheel 25 associated with a rotation transducer. To achieve this, the friction wheel is in functional connection with a flexible tube 24 which is rigidly connected to the measuring head 9. Thus, this measuring device makes it possible to determine internal diameters at two positions located at axially spaced locations from one another in a tube 2.
