Catheter device with a drive shaft cover

Abstract

The invention relates to a catheter device (1), comprising a drive shaft (4) extending from a driving region (16) of the catheter device (1) to a distal end region (8) of the catheter device (1), a rotor (2) which is attached to the drive shaft (4) in the distal end region (8) and a distal bearing (9) for bearing a distal end of the drive shaft (4). The distal bearing comprises a drive shaft cover (11) which is configured to cover a section of the drive shaft (4) extending distally of the rotor (2). On a distal side of the rotor (2), a radially inner part of the rotor (2) is recessed with respect to radially outer parts of the rotor (2) to form a hollow space (2.3) surrounding the drive shaft (4), wherein a proximal end of the drive shaft cover (11) lies in said hollow space (2.3).
