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.

Claims

1. A fluid injection and inflation system, comprising:

a fluid delivery system comprising at least one pressurizing device;

wherein the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode wherein the at least one pressurizing device delivers fluid to the fluid path for a fluid injection procedure, or in a balloon inflation mode wherein the at least one pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter.

2. A fluid injection and inflation system as claimed in claim 1, wherein the control unit comprises an operator interface to input fluid injection mode and balloon inflation mode parameters for the selected procedure.

3. A fluid injection and inflation system as claimed in claim 2, wherein the operator interface is commonly housed with the at least one pressurizing device.

4. A fluid injection and inflation system as claimed in claim 1, wherein at least one pressurizing device comprises a syringe pump and the control unit controls operation of the syringe pump via a pump controller.

5. A fluid injection and inflation system as claimed in claim 1, further comprising an operator control connected to the control unit.

6. A fluid injection and inflation system as claimed in claim 5, wherein the operator control comprises a handheld control device.

7. A method of delivering fluid to a catheter comprising a balloon, comprising:

providing a fluid delivery system comprising;

at least one pressurizing device;

a fluid path adapted to connect the at least one pressurizing device to the catheter;

a control unit operable to control the fluid delivery system; and

an operator control connected to the control unit;

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

actuating the operator control to perform either the fluid injection procedure or balloon inflation procedure whereby fluid is delivered to the catheter in accordance with the fluid injection or balloon inflation parameters inputted into the control unit.

8. A fluid injection and inflation system, comprising:

a fluid delivery system comprising at least one pressurizing device connected to at least one fluid source;

a fluid path adapted to connect the at least one pressurizing device to a patient via a catheter inserted in the patient, the catheter comprising a fluid injection lumen and a balloon inflation lumen for inflating a balloon associated with the catheter; 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 at least one pressurizing device delivers fluid to the fluid injection lumen via the fluid path for a fluid injection procedure, or in a balloon inflation mode wherein the at least one pressurizing device delivers fluid to the balloon inflation lumen for a balloon inflation procedure wherein the balloon associated with the catheter is inflated with fluid.

9. A fluid injection and inflation system as claimed in claim 8, wherein the at least one fluid source comprise a first fluid source containing contrast and a second fluid source containing a diluent media.

10. A fluid injection and inflation system as claimed in claim 9, wherein the at least one pressurizing device delivers contrast from the first fluid source to the fluid injection lumen in the fluid injection mode, and delivers a mixture of contrast and diluent from the first and second fluid sources to the balloon inflation lumen in the balloon inflation mode.
