First Claim
Patent Images
1. A catheter device comprising:
- a hollow catheter having a catheter cavity;
a moveable shaft, rotatably disposed within the hollow catheter and at least partially disposed within the catheter cavity of the hollow catheter, the moveable shaft having a proximal end portion;
a proximal coupling device for coupling of a drive device to the hollow catheter, the coupling device having;
a coupling cavity which is open towards a proximal direction and into which at least a portion of the moveable shaft protrudes, the coupling cavity defining a radiation chamber and including a radiation window, the radiation window being permeable to ultraviolet (UV) radiation and impermeable to liquid, wherein the radiation window hermetically seals the radiation chamber; and
a connection disposed within the coupling cavity at the proximal end portion of the movable shaft, the connection configured to connect the moveable shaft to a motor shaft;
wherein the coupling cavity is coupled to the hollow catheter such that fluid can flow between the coupling cavity and the hollow catheter.
