Abstract
A device for removing fluid from a first bodily cavity and for directing that fluid into a second bodily cavity while avoiding risks of infection and, in one embodiment, excessive dehydration of the first bodily cavity. The device includes an uptake tube having a proximal end in fluid communication with the first bodily cavity and a distal end in fluid communication with a pump, and an outflow tube having a proximal end in fluid communication with the pump and a distal end in fluid communication with the second bodily cavity. The distal end of the uptake tube may be coupled to a reservoir configured to expand upon ingression of fluid into the reservoir and to contract upon removal of fluid due to a negative pressure provided by the pump.

26. An implantable fluid management device comprising:
-
an implantable pump; a reservoir; an uptake tube having a proximal end in fluid communication with the reservoir and a distal end in fluid communication with the pump; and an outflow tube having a proximal end in fluid communication with the pump and a distal end configured for fluid communication with a patient'"'"'s bladder, wherein actuation of the pump is triggered by a sensor in fluid communication with the reservoir, the sensor directly monitoring pressure to prevent excessive vacuum from being applied to a peritoneal cavity. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
