CATHETER DEVICE

摘要

The catheter device comprises a motor located at the proximal end of the catheter device, and a drive shaft which extends from the proximal end area of the catheter device to the distal end area and which drives a rotary element located at the distal end of the catheter device. The catheter device further comprises a tubular catheter shaft which encloses the drive shaft and which extends from the proximal end area to the distal end area of the catheter device. The drive shaft is connected to the motor at the proximal end of the catheter device by means of a coupling. The coupling is a magnetic coupling with a proximal magnet unit and a distal magnet unit. The proximal magnet unit is connected to the motor, and the distal magnet unit is connected to the drive shaft. The distal magnet unit is mounted in a coupling housing in a leaktight manner. The proximal end of the catheter shaft is connected to the coupling housing in a leaktight manner.
