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.
