Systems and methods for controlling a volume of fluid within a portion of a patient's body

A system comprising:

• a dual chamber probe, wherein the dual chambers of the probe are configured to be disposed within a portion of a patient's body, comprising:
• a first channel comprising a drain element in a first chamber to add or remove fluid from the portion of the patient's body;
• a second channel comprising a volume changing element in a second chamber to modulate a volume of the portion of the patient's body to facilitate addition or removal of the fluid, wherein the volume changing element is configured to be positioned within the portion of the patient's body where the volume is to be modulated, such that the volume changing element directly affects the volume of the portion of the patient's body, and wherein a change in the volume of the portion of the patient's body causes fluid to be drained via the drain element in the first channel;
• a volume control coupled to the volume changing element to control a modulation of the volume of the portion of the patient's body;
• and,
• a fluid reservoir, wherein the fluid reservoir is in two-way communication with the drain element, such that the fluid from the portion of the patient's body can be stored in the fluid reservoir and the fluid can be added back to the portion of the patient's body on demand in response to the changes to the volume of the portion of the patient's body effected by the second channel's response to the volume control.
