Claim 0:
1. 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, wherein the tubular member is configured to move translationally relative to the catheter; 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.
