1. A lymphatic drainage system for lymphatic fluid management in a patient, the lymphatic drainage system comprising an implantable pump comprising:
a housing configured to be implanted within the patient;
an inlet tube disposed within the housing, the inlet tube configured to be in fluid communication with a first bodily portion to receive bodily fluid;
an outlet tube disposed within the housing, the outlet tube configured to be in fluid communication with a second bodily portion;
a fluid chamber disposed within the housing and coupled to the inlet tube and the outlet tube such that the fluid chamber is configured to be in fluid communication with the inlet tube and the outlet tube;
a rotor disposed within the housing and configured to rotate to change a volume of the fluid chamber; and
a lever in mechanical communication with the rotor and configured to move between an open position and a closed position responsive to rotation of the rotor to cause the inlet tube to periodically kink such that the bodily fluid is pumped from the first bodily portion towards the second bodily portion via the inlet tube, the fluid chamber, and the outlet tube.
