Abstract

One embodiment provides a method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure. In this embodiment, the method includes drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device, removing an amount of air from the balloon catheter during a second motorized operation of the inflation device, and injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter The powered inflation device may be a stand-alone device in one embodiment. In one embodiment, the powered inflation device is coupled to an angiographic injector system. When it is coupled to an angiographic injector system, the balloon inflation device and the injector system may be controlled by a common control panel, or console, in one embodiment.

Claims

1. A method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure, the method comprising:

drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device;

removing an amount of air from the balloon catheter during a second motorized operation of the inflation device; and

injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter.

2. The method of claim 1, wherein the amount of medical fluid comprises an amount of contrast media.

3. The method of claim 2, wherein the amount of medical fluid further comprises an amount of diluent.

4. The method of claim 1, wherein drawing the amount of medical fluid from the fluid reservoir comprises filling a first syringe with the amount of medical fluid during movement of a plunger of the first syringe in a first direction.

5. The method of claim 4, wherein removing the amount of air from the balloon catheter comprises aspirating the amount of air from the balloon catheter during movement of the plunger of the first syringe in the first direction.

6. The method of claim 4, wherein removing the amount of air from the balloon catheter comprises aspirating the amount of air from the balloon catheter during movement of a plunger of a second syringe, and wherein the first syringe is coupled to the second syringe within the inflation device.

7. The method of claim 4, wherein removing the amount of air from the balloon catheter comprises aspirating the amount of air from the balloon catheter during operation of a vacuum pump, and wherein the first syringe is coupled to the vacuum pump within the inflation device.

8. The method of claim 4, wherein injecting the amount of medical fluid from the inflation device into the balloon catheter comprises injecting the amount of medical fluid during movement of the plunger of the first syringe in a second direction, the second direction being opposite to the first direction.

9. The method of claim 1, further comprising:

injecting the amount of air into a waste container.

10. The method of claim 1, further comprising:

removing the amount of medical fluid from the balloon catheter during a fourth motorized operation of the inflation device to deflate the balloon.

11. The method of claim 1, further comprising:

providing a control panel coupled to the inflation device to receive user input and to display information related to use of the inflation device.

12. The method of claim 11, further comprising:

receiving on the control panel user input to set an inflation rate or a deflation rate.

13. The method of claim 11, further comprising:

receiving on the control panel user input to set an inflation pressure limit.

14. The method of claim 11, further comprising:

displaying on the control panel a pressure-volume curve during inflation of the balloon at the distal end of the balloon catheter.

15. The method of claim 11, further comprising:

receiving on the control panel a single user input command to cause the inflation device to perform the acts of drawing the amount of medical fluid from the fluid reservoir and removing the amount of air from the balloon catheter.

16. A powered inflation device to prepare a balloon catheter for use during a medical procedure, the inflation device comprising:

a motor;

a fluid reservoir;

a pressurizing unit operatively coupled to both the motor and the fluid reservoir;

wherein, during a first operation, the motor causes the pressurizing unit to draw an amount of medical fluid from the fluid reservoir into the inflation device;

wherein, during a second operation, the motor causes the inflation device to remove an amount of air from a balloon catheter that is coupled to the inflation device; and

wherein, during a third operation, the motor causes the pressurizing unit to inject the amount of medical fluid from the inflation device into the balloon catheter to inflate a balloon located at a distal end of the balloon catheter.

17. The inflation device of claim 16, wherein the pressurizing unit comprises a syringe.

18. The inflation device of claim 16, wherein, during the second operation, the motor causes the pressurizing unit to remove the amount of air from the balloon catheter.

19. The inflation device of claim 16, wherein the amount of medical fluid comprises an amount of contrast media.

20. The inflation device of claim 19, wherein the amount of medical fluid further comprises an amount of diluent.

21. The inflation device of claim 16, wherein, during the second operation, the motor causes a second pressurizing unit to remove the amount of air from the balloon catheter, the second pressurizing unit being coupled to the pressurizing unit.

22. The inflation device of claim 16, wherein, during the second operation, the motor causes a vacuum pump to remove the amount of air from the balloon catheter, the vacuum pump being coupled to the pressurizing unit.

23. The inflation device of claim 16, further comprising a waste container.

24. The inflation device of claim 16, further comprising a control panel to receive user input and to display status information.

25. The inflation device of claim 16, wherein, during a fourth operation, the motor causes the pressurizing unit to remove the amount of medical fluid from the balloon catheter to deflate the balloon.

26. The inflation device of claim 16, wherein the inflation device is a stand-alone device.

27. The inflation device of claim 16, wherein the inflation device is coupled to an angiographic injector system.

28. The inflation device of claim 27, wherein a common control panel is operable to control both the inflation device and the angiographic injector system.

29. A powered inflation device to prepare a balloon catheter for use during a medical procedure, the inflation device comprising:

means for drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device;

means for removing an amount of air from the balloon catheter during a second motorized operation of the inflation device; and
