1. A balloon retention urinary catheter for insertion into a bladder of a patient, comprising:
a) an elongate catheter shaft extending between a proximal end and a distal end;
b) a balloon adjacent the distal end;
c) a drainable port distal of the balloon; and
d) a distal tip at the distal end, the distal tip including a polymer component that is insoluble in urinary fluid in the bladder and which is combined with an eluting component that is dissolvable by urinary fluid and adapted to elute from the distal tip in the presence of urinary fluid in order to increase flexibility of the distal tip.
