| 摘要 |
The invention relates to a catheter arrangement which comprises at least a first basic element and a second basic element, which second basic element is arranged such that it is slidably arranged in the first basic element over at least part of its length and has a sensor unit that is provided for determining a position and/or mutual position shift of the first basic element and the second basic element, to generate at least a sensor value that is assigned to a measurable property of the catheter arrangement. The repeated reaching of a once-defined position is allowed by such a catheter arrangement, so that after expanding a vessel constriction, a stent can be taken to the same position without having to take X-rays for verification of the position, which are burdensome to the patient.
