Catheter device with a coupling device for a drive device

摘要

The device has a hollow catheter (1) arranged in a catheter cavity, and a moveable shaft provided with a proximal coupling device for detachable coupling a drive device. The coupling device has a coupling cavity (7) opened towards the drive device, where the shaft or an extension (5) of the shaft protrudes into the coupling cavity with a connection element for mechanical coupling of a motor shaft (16). The coupling cavity has a germ barrier (9') for reducing the pathogenicity of pathogenic substances or microorganisms.
