Title: CATHETER PUMP HAVING A DRIVE UNIT AND A CATHETER
Abstract:
The invention relates to a catheter pump having a drive unit and a catheter, the catheter having a pump head for inserting into the aorta and having a rotatably arranged rotor shaft for driving an expandable conveying element provided on the pump head, the catheter having, at the proximal end thereof, a coupling section, which is connected to the rotor shaft for conjoint rotation and which can be rotated about a coupling axis, and the drive unit having a drive and a drive section, which can be driven in rotation about a drive axis by the drive, the coupling section and/or the drive section having magnet elements for contactless mutual rotational coupling, and the coupling axis and the drive axis being spaced from each other by a distance a in the perpendicular direction in such a way that the magnetic field of the magnet elements pushes the coupling section in a direction extending perpendicularly to the coupling axis.
