| 摘要 |
The present invention relates to a catheter comprising a catheter body section (1) and at least one catheter tip section (2). The catheter body section (1) can extend in a longitudinal direction. The at least one catheter tip section (2) may be located on a distal side of the catheter body section (1). In a first operation mode of the catheter usable during insertion thereof, the catheter body section (1) and the at least one catheter tip section (2) can be commonly moved substantially in the longitudinal direction. In a second operation mode of the catheter usable when the catheter has reached a position where it should not be advanced any further, the catheter body section (1) and the at least one catheter tip section (2) may be moved relative to each other, so that the at least one catheter tip section (2) can be separated from the catheter body section (1).
