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 configured to be in fluid communication with a first bodily portion to receive bodily fluid;
an outlet tube configured to be in fluid communication with a second bodily portion;
a fluid chamber disposed within the housing and 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 first membrane defining a wall of the fluid chamber, the first membrane configured to stretch responsive to rotation of the rotor to reduce the volume of the fluid chamber towards a closed position 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,
wherein the first membrane is configured to be positioned at least partially around the rotor.
