Catheter device
First Claim
1. A catheter device comprising:
- a drive shaft having a proximal end and a distal end;
a rotor, connected to the drive shaft;
a pump head comprising an inlet, an outlet, and an expandable and collapsible pump housing having a proximal end and a distal end, wherein the rotor is located in the expandable and compressible pump housing;
a body cap, wherein the body cap has a proximal end and a distal end, the proximal end being coupled to a distal end of the pump head by a body element, and wherein the body cap comprises an atraumatic ball; and
the body element is an elongate tubular flexible projection, having proximal and distal ends, that projects distally away from the distal end of the pump housing and forms a flexible connection between the body cap and the distal end of the pump housing, wherein the proximal end of the atraumatic ball is positioned distally relative to the distal end of the body element.

Abstract
The catheter device comprises a motor 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. 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.
