Abstract
The invention relates to a catheter device, having a catheter, an actuation device at a first end of the catheter and also a mechanical transmission element for transmitting a movement along the catheter to the actuation device, the actuation device having a coupling element which is connected to the transmission element and can be actuated by the latter relative to the longitudinal direction of the catheter in a first degree of freedom, and also a conversion element which can be actuated by the coupling element and which converts the actuation movement at least partially into a movement in a second degree of freedom. As a result, a combined movement at the distal end of the catheter can be produced particularly simply for compression and release of a functional element.

1-18. (canceled)
A catheter device, comprising:
- a catheter having a proximal end and a distal end;
- a blood pump, comprising:
- a rotor, and
- a housing enclosing the rotor, the housing coupled to the distal end of the catheter;
- a cap surrounding the catheter and configured to at least partially enclose the blood pump in a compressed state;
- a coupling element surrounding the catheter and coupled to the cap such that the cap may rotate around the catheter independent of the coupling element;
- a flexible drive shaft having a proximal end and a distal end, wherein the catheter surrounds the flexible drive shaft;
- a tubular member having a distal end and a proximal end and surrounding at least a portion of the catheter, the distal end of the tubular member being coupled to the coupling element;
- and
- a conversion element coupled to or integrated with the cap, the conversion element being configured to convert translational movement of the coupling element relative to the catheter at least partially into a rotational movement of the cap relative to the catheter.
