1. An implantable fluid management device, comprising: a body structure defining one or more fluid-flow passageways configured to receive a biological fluid of a biological subject;one or more sensors configured to detect at least one characteristic associated with the biological fluid;a first actively controllable excitation component configured to deliver a first sterilizing energy stimulus to a biological fluid received within at least one of the one or more fluid-flow passageways;a second actively controllable excitation component configured to deliver a second sterilizing energy stimulus to a tissue proximate an outer surface of the implantable fluid management device; anda control means operable to actuate concurrent-delivery of the first sterilizing energy stimulus to a biological fluid received within at least one of the one or more fluid-flow passageways, and the second sterilizing energy stimulus to a tissue proximate an outer surface of the implantable fluid management device, responsive to a detected change in a parameter associated with a biological fluid received within the one or more fluid-flow passageways. 2. The implantable fluid management device of claim 1, wherein the first energy stimulus comprises an electromagnetic energy stimulus, an electrical energy stimulus, an ultrasonic energy stimulus, or a thermal energy stimulus, and the second energy stimulus comprises a different one of an electromagnetic energy stimulus, an electrical energy stimulus, an ultrasonic energy stimulus, or a thermal energy stimulus. 3. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes an inner surface that is internally reflective to electromagnetic radiation. 4. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes a surface that is internally reflective to ultraviolet radiation. 5. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes a surface that is internally reflective to infrared radiation. 6. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes a surface having a reflective coating. 7. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes an ultraviolet energy reflective material. 8. The implantable fluid management device of claim 1, wherein the one or more sensors include one or more optical density sensors. 9. The implantable fluid management device of claim 1, wherein the one or more sensors include one or more refractive index sensors. 10. The implantable fluid management device of claim 1, wherein the one or more sensors include one or more refractive index sensors having one or more fiber optic refractive index sensors. 11. The implantable fluid management device of claim 1, wherein the one or more sensors include one or more surface plasmon resonance sensors. 12. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are controllably actuatable between at least a first wettability state and a second wettability state. 13. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are energetically actuatable between at least a first wettability state and a second wettability state. 14. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are electro-chemically actuatable between at least a first wettability state and a second wettability state in the presence of an ultraviolent energy. 15. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are photo-chemically actuatable between at least a first wettability state and a second wettability state in the presence of an ultraviolent energy. 16. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are electrically actuatable between at least a first wettability state and a second wettability state in the presence of an ultraviolent energy. 17. The implantable fluid management device of claim 1, the body structure further comprising: one or more surface regions that are controllably switchable between a zwitterionic state and a non-zwitterionic state. 18. The implantable fluid management device of claim 1, the body structure further comprising: at least one of an antimicrobial coating and a non-fouling coating. 19. The implantable fluid management device of claim 1, the body structure further comprising: a surface region that is energetically actuatable between an antimicrobial state and a non-fouling state. 20. The implantable fluid management device of claim 1, wherein at least a portion of the body structure includes at least one of poly(carboxybetaine methacrylate) (pCBMA), poly(carboxybetaine acrylic amide) (pCBAA), poly(oligo(ethylene glycol) methyl ether methacrylate) (pOEGMA), poly(N,N-dimethyl-N-(ethoxycarbonylmethyl)-N-[2′-(methacryloyloxy)ethyl]-ammonium bromide), cationic pC8NMA, switchable pCBMA-1 C2, and pCBMA-2.
