1. A balloon catheter, comprising:
- an elongate body having an inflation lumen;
a balloon coupled to the elongate body and in fluid communication with the inflation lumen; and
a fluid control valve integrated with the balloon catheter, where the fluid control valve regulates a flow of a fluid past the balloon in an expanded state at an adjustable rate greater than a no-flow rate and less than a full-flow rate.

10. The method of forming a balloon catheter, comprising:
-
providing an elongate body having an inflation lumen; coupling a balloon to the elongate body to be in fluid communication with the inflation lumen; and integrating a fluid control valve with the balloon catheter, where the fluid control valve can regulate a flow of a fluid past the balloon in an expanded state at an adjustable rate greater than a no-flow rate and less than a full-flow rate. - View Dependent Claims (11, 12, 13, 14, 15)
