Abstract
Catheter device, having a hollow catheter in the catheter cavity of which a moveable shaft is guided, having a proximal coupling device, for detachable coupling of a drive device, the coupling device having a coupling cavity which is open towards the drive device and into which the shaft or an extension of the shaft protrudes with a connection element for mechanical coupling of a motor shaft, the coupling cavity having a germ barrier for reducing the pathogenicity of pathogenic substances or microorganisms.
Claims20
A catheter device comprising:
- a catheter having a lumen, a proximal end, and a distal end;
- a first housing having a proximal end and a distal end, the distal end of the housing being coupled to the proximal end of the catheter, and the first housing comprising:
- a catheter cavity in communication with the lumen of the catheter;
- a coupling cavity;
- and
- a germicidal gel within the coupling cavity;
- and
- a first seal between the catheter cavity and the coupling cavity, the first seal being configured to prevent the germicidal gel migrating from the coupling cavity to the catheter cavity;
- a second housing configured to be releasably coupled to the first housing;
- a motor arranged within the second housing, the motor having a motor shaft extending through a wall of the second housing;
- and
- a drive shaft having a proximal end and a distal end, the proximal end of the drive shaft being configured to be releasably coupled to the motor shaft when the second housing is releasable coupled to the first housing, and the drive shaft extending at least from the coupling cavity, through the first seal, to the catheter cavity.
