a catheter having a distal outlet end and a proximal insertion end;
a wetting agent storage chamber;
an external housing, the external housing at least partially enclosing the catheter and the storage chamber; and,
a sheath connected between the catheter and the storage chamber such that withdrawing the catheter from the external housing causes withdrawal of the storage chamber from the external housing via the sheath;
