<p>An apparatus (500) is operable to communicate fluid. An exemplary apparatus comprises a housing (502) and a fluid reservoir within the housing. An actuator (504) is operationally engaged with the fluid reservoir. The actuator is operable to effect communication of fluid from or into the fluid reservoir. A sensor (530) is in fluid communication with the fluid reservoir. The sensor is operable to sense a physical parameter of fluid that is in communication with the fluid reservoir as the fluid is communicated from or into the fluid reservoir. An indicator (508) is in communication with the sensor. The indicator is operable to display the physical parameter sensed by the sensor. The apparatus may be used to inject fluid into or withdraw fluid from an implanted gastric band system or for a variety of other uses. Fluid pressure may be adjusted and sensed, and resulting data may be displayed, by a single, integrated instrument.</p> |
