Abstract

A system and method is provided including a fluid communications network that sends priming and waste fluid to a waste bag, obviating the presence of open fluid containers in an operating room or catheter lab. The fluid communications network is constructed and arranged to allow nearly automated priming and bubble removal, thereby reducing the possibility of operator caused errors in set-up and reducing the time required for set-up. The fluid communications network is useable for attachment to a balloon catheter for inflation thereof. In order to provide greater control and automation of the inflation of the balloon catheter, a conversion kit is provided that can be used to convert an existing automatic injector into an injector useable for automatically controlling the small amount of injection fluid typically associated with balloon catheters.

Claims

1. An automatic medical balloon inflation device comprising:

a fluid pump attachable to a balloon catheter and configured to provide fluid pressure to a balloon at a distal end of the balloon catheter, wherein the balloon catheter is associated with baseline pressure data that is representative of inflation characteristics of the balloon catheter under a no-load condition;

a computer configured to control the fluid pressure created by the fluid pump; and

a pressure sensor operably attached to the computer and configured to provide data to the computer corresponding to the fluid pressure created by the fluid pump,

wherein prior to the fluid pump providing the fluid pressure to the balloon for a balloon inflation procedure, the computer is configured to receive computer-readable data associated with the balloon catheter comprising the baseline pressure data that is representative of the inflation characteristics of the balloon catheter under the no-load condition, and

wherein when the fluid pump provides the fluid pressure to the balloon during the balloon inflation procedure, the computer is configured to compare the baseline pressure data to the data received by the computer from the pressure sensor corresponding to the fluid pressure created by the fluid pump.

2. The automatic medical balloon inflation device of claim 1 further comprising a program segment, stored in a computer readable medium readable by the computer, that when executed enables the computer to determine an existence of predetermined characteristics of the data received by the computer from the pressure sensor, and to react to the characteristics in a predetermined manner.

3. The automatic medical balloon inflation device of claim 1 further comprising a bar code reader useable to upload the baseline pressure data to the computer.

4. The automatic medical balloon inflation device of claim 1, wherein the computer is further configured to shut down the inflation device if the comparison indicates a safety issue associated with the balloon catheter.

5. The automatic medical balloon inflation device of claim 1, wherein the computer is further configured to hold the fluid pressure created by the pump at a predetermined level based upon the comparison.

6. The automatic medical balloon inflation device of claim 1 further comprising a monitor operably connected to the computer and capable of displaying data representative of the data received from the pressure sensor.

7. The automatic medical balloon inflation device of claim 6 further comprising a program segment, stored in a computer readable medium readable by the computer, that when executed enables the computer to send signals to the monitor to display a graph of fluid pressure versus time.

8. The automatic medical balloon inflation device of claim 6 further comprising a program segment, stored in a computer readable medium readable by the computer, that when executed enables the computer to send signals to the monitor to display a graph of balloon volume versus time.
