Abstract
A balloon catheter system for use by an operator for treating a targeted vein, the balloon catheter system comprising a balloon catheter, a fluid source and a control system. The balloon catheter includes a balloon having a balloon interior, the balloon configured to undergo one or more inflation cycles. The fluid source contains a cryogenic fluid that is selectively delivered to the balloon interior. The control system is configured to selectively control the delivery of the fluid to the balloon interior and to that selectively adjusts an inflation pressure to of the balloon interior based on a number of inflation cycles undergone by the balloon so as to selectively adjust an inflated balloon diameter of the balloon.
