Abstract

An apparatus for testing a vessel wall includes a rail and a carriage running on the rail. An inclining and swiveling telescoping arm has an end being pivotably connected to the carriage and a free end. The telescoping arm has curved members with U-shaped cross sections. A drive mechanism for extending and retracting the telescoping arm includes a pusher tube having tensile strength and resistance to compression for driving the members in common and a motor for driving the pusher tube. A test unit is carried by the free end of the telescoping arm and a data line is connected between the test unit and an evaluation unit.
