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.
Claims20
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 at least one of the reservoir and a peritoneal cavity, the sensor directly monitoring pressure to prevent excessive vacuum from being applied to the peritoneal cavity.
A method for transferring fluid, the method comprising:
- implanting a pump within a patient;
- implanting an uptake tube having a proximal end in fluid communication with a reservoir and a distal end in fluid communication with the pump;
- implanting an outflow tube having a proximal end in fluid communication with the pump and a distal end configured for fluid communication with the patient's bladder;
- triggering actuation of the pump by a sensor in fluid communication with at least one of the reservoir and a peritoneal cavity;
- and
- directly monitoring pressure to prevent excessive vacuum from being applied to the peritoneal cavity.
