1. A device, comprising:

  • a controller contained within an implantable housing;

    a physiological sensor interfaced to the controller for measuring a physiological variable; and

    ,an occluding structure adapted for implantation within a renal lymphatic vessel and operable by the controller to occlude the renal lymphatic vessel and thereby restrict flow therethrough;

    wherein the occluding structure comprises a catheter incorporating an expandable balloon adapted for disposition in the renal lymphatic vessel and a pressurized fluid source for expanding the balloon operable by the controller;

    a transthoracic impedance sensor for detecting pulmonary edema; and

    ,wherein the controller is programmed to operate the occluding structure in response to the measured physiological variable and further programmed to operate the occluding structure if pulmonary edema is detected.
