CATHETER DEVICE
First Claim
1. A catheter device comprising:
- a distal end and a proximal end;
a motor located at the proximal end;
a drive shaft, extending from the proximal end to the distal end for driving a rotating element located at the distal end of the catheter device, wherein at the proximal end, the drive shaft is connected to the motor by a clutch, wherein the clutch is a magnetic clutch with a proximal and a distal magnet unit, wherein the proximal magnet unit is connected to the motor, and the distal magnet unit is connected to the drive shaft, and wherein the distal magnet unit is supported in a clutch housing and physically separated from the proximal magnet unit by a wall.

Abstract
The catheter device comprises a motor located at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section of the catheter device. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing. The proximal end of the catheter body makes a fluid-tight connection with the clutch housing.
