Medical fluid injection and inflation system
First Claim
1. 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.

Abstract
A combined fluid injection and inflation system is disclosed and includes a fluid delivery system including at least one pressurizing device, a fluid path, and a control unit. The fluid path is adapted to connect the pressurizing device to a patient via a catheter including a balloon and inserted in the patient. The control unit is operable to control the fluid delivery system. In operation, the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode or in a balloon inflation mode. In the fluid injection mode the pressurizing device delivers fluid to the fluid path for a fluid injection procedure. In the balloon inflation mode, the pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter. An operator control may be connected to the control unit for controlling the fluid delivery system and may be a handheld device.

14. A method of delivering fluid to a catheter, comprising:
-
providing a fluid delivery 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; inputting fluid injection and/or balloon inflation parameters into the control unit for performing a fluid injection procedure and/or a balloon inflation procedure; and selectively actuating the operator control to perform either the fluid injection procedure wherein the first pressurizing device delivers fluid from the first fluid source to the fluid injection lumen, or the balloon inflation procedure 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 to inflate the balloon in accordance with the fluid injection or balloon inflation parameters inputted into the control unit.
