Implantable fluid management device for the removal of excess fluid
First Claim
1. An implantable fluid management device comprising:
- an implantable pump;
a reservoir configured for implantation in the peritoneal cavity, the reservoir configured to expand upon egress of fluid into the reservoir and to contract upon removal of the fluid from the 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 the peritoneal cavity.

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.
