Abstract

The indicator for the detection of cross-sectional variations in an elongated body lumen, such as a ureter, comprises a hollow part (60), to which is connected an indicator part (10) comprising a probe body (30) of flexible material. The indicator part comprises a first end part fixed to the hollow part. The probe body is formed as a catheter-type component projecting from the hollow part, which at its free end has a rigid connection. The probe body is hollow, the interior (12) of which forms part of a closed cavity in which pressure varies with compression of the probe body. A pressure-monitoring component (15) indicates the extent of the pressure in the cavity (13). In the pressure-monitoring component is a membrane (15) with a fixture ring (16), which centers the membrane when it is inserted in the hollow part.
