1. A balloon catheter system comprising:
a balloon catheter including a balloon having a balloon interior, the balloon configured to undergo one or more inflation cycles;
a fluid source that contains a fluid that is selectively delivered to the balloon interior; and
a control system configured to control the delivery of the fluid to the balloon interior at a first inflation pressure to achieve a first targeted balloon diameter, the first inflation pressure being selected by the control system based on a number of inflation cycles undergone by the balloon;
wherein the control system is configured to select the first inflation pressure based on empirical data stored within the control system; and
wherein the empirical data includes data on at least two of balloon materials, balloon dimensions, balloon compliance, inflation pressure, and previous number of balloon inflations of the balloon.
