A catheter tip for a catheter assembly, the catheter assembly having a main body with a first end portion positionable within a fluid filled space of a body and a second end portion adapted to extend outward from the fluid filled space, the catheter tip connectable to the second end portion of the main body, the catheter tip comprising:
a housing having a cavity defined therein; and
a rotating element positioned within the cavity, the rotating element connectable to the first end portion of the main body such that rotation of the rotating element results in at least one of rotational and linear movement of the first end portion of the main body within the fluid filled space, wherein the rotating element is semicircular in shape and positioned such that the rotating element freely rotates relative to the housing upon movement of the body.
