Abstract
The invention relates to a guide wire assembly, having a guide wire (2) having a distal end portion (16) and a proximal end, wherein a measuring device (14) is mounted in the distal end portion (16) of the guide wire (2). It also has an interface cable (4) having a first end connectable to a control unit (8), and a second end connectable to the proximal end of the guide wire. Furthermore there is provided information storage (20; 22; R.sub.x) on the interface cable, containing calibration/temperature compensation data, uniquely characteristic of the measuring device. The data and an uncompensated output from the measuring device forming the input for calculation of a correct measurement value.
