Patent ID: 8192397

Claim:
A fluid injection and inflation system, comprising: a catheter comprising a fluid injection lumen and a balloon inflation lumen connected to a balloon; a first fluid source; a second fluid source; a fluid path to connect the first fluid source and the second fluid source to the catheter, the fluid injection lumen in fluid connection with the first fluid source and the balloon inflation lumen in fluid connection with the first fluid source and the second fluid source, the balloon inflation lumen operable to inflate the balloon; a fluid delivery system comprising a first pressurizing device and a second pressurizing device operably associated with the fluid path; and a control unit operable to control the fluid delivery system; wherein the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode wherein the first pressurizing device delivers fluid from the first fluid source to the fluid injection lumen for a fluid injection procedure, and in a balloon inflation mode wherein the second pressurizing device delivers a mixture of fluids from the first fluid source and the second fluid source to the balloon inflation lumen for a balloon inflation procedure wherein the balloon is inflated with the mixture of fluids.
