A rapid exchange catheter system has a long flexible inner catheter (1), a guide wire (3) and an outer flexible tube type catheter. The inner catheter has an inner diameter equal to the guide wire, one distant end and one close end. It extends from an inlet at the distant end to a side orientated opening (5) at the close end. The outer catheter (2) has a side orientated opening (6) for the guide wire (3). The inner catheter moves axially within the outer catheter and securing devices prevent the rotation of the catheters relative to each other. Therefore, the inner (5) and outer (6) openings stay aligned and relative axial displacement of the catheters is made easy. |
