REUSABLE AIR CHARGER AND ASSOCIATED MULTI-LUMEN DISPOSABLE CATHETER, AND RELATED METHODS

A diagnostic manometry device comprises a catheter including a plurality of lumens, a fluid charger configured to operatively couple with the catheter, and a charging mechanism for moving fluid simultaneously from fluid pressure chambers of the plurality of fluid pressure chambers into the respective lumens of the plurality of lumens when the catheter is operatively coupled with the fluid charger. Each fluid pressure chamber of the plurality of fluid pressure chambers is configured to be in fluid communication with a respective lumen of the plurality of lumens when the catheter is operatively coupled with the fluid charger. Each pressure sensor of the plurality of pressure sensors is located and configured to measure a fluid pressure change in a respective fluid pressure chamber of the plurality of fluid pressure chambers. Additional manometry devices and methods of forming a manometry device are also disclosed.
