1. A balloon sinuplasty tool, comprising:
an enclosure;
a rotatable knob retained by, and protruding from, the enclosure;
a tube having a proximal end retained by the enclosure, the tube having an axis of symmetry;
a guidewire insertion tube configured to guide a guide wire therethrough and hold a balloon thereon,
a balloon insertion mechanism; and
a Geneva drive retained within the enclosure, the Geneva drive comprising a drive wheel fixedly attached to the rotatable knob and a driven wheel fixedly attached to the proximal end of the tube, so that an axis of rotation of the driven wheel coincides with the axis of symmetry of the tube,
whereby a continuous rotation of the rotatable knob causes the tube to rotate about the axis of symmetry in discrete angular steps.
