Claim 19:
20. 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, wherein an inner diameter of the cap is smaller than an outer diameter of the housing of the blood pump when the blood pump is in an uncompressed 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.
