1. An implantable device for retracting prostatic tissue of a patient, the implantable device comprising:
a shaft having a proximal end and a distal end disposed opposite one another in a direction of a longitudinal axis of the shaft;
a proximal balloon fixedly attached to the shaft, the proximal balloon disposed closer to the proximal end than to the distal end;
a distal balloon fixedly attached to the shaft, the distal balloon disposed closer to the distal end than to the proximal end; and
an intermediate balloon fixedly attached to the shaft, the intermediate balloon disposed between the proximal balloon and the distal balloon,
wherein the shaft defines a first lumen in fluid communication with a first reservoir defined by the proximal balloon and a second reservoir defined by the distal balloon and fluidically isolated from a third reservoir defined by the intermediate balloon, and the intermediate balloon is disposed closer to the distal balloon than to the proximal balloon.
