1. A system for modulating a physiological process, comprising: an implantable device comprising an energy source, the implantable device constructed and arranged to provide a signal; andan electrical lead body connected to the implantable device and comprising: a plurality of transducer contacts in close proximity to an end of the electrical lead body;a control unit positioned within the lead body in close proximity to the plurality of transducer contacts and constructed and arranged to enable precise delivery of signals to a predetermined treatment site, the control unit configured to receive at least one first input signal from the implantable device and to transmit a plurality of output signals to the plurality of transducer contacts, and further configured to receive at least one second input signal from the plurality of transducer contacts, the control unit comprising: at least one electrical input contact; anda plurality of electrical output contacts, wherein a quantity of the electrical output contacts is greater than a quantity of the electrical input contacts,wherein the plurality of output signals is modulated in response to the at least one second input signal from the plurality of transducer contacts, and the plurality of output signals is based at least in part on the at least one first input signal from the implantable device and on a control function of the control unit. 2. The system of claim 1, wherein the plurality of transducer contacts are disposed to perform at least one of sensing at least one parameter of the physiological process, transmitting at least one parameter of the physiological process, stimulating the physiological process, and inhibiting the physiological process. 3. The system of claim 2, wherein the control unit is constructed and arranged to record at least one parameter of the physiological process. 4. The system of claim 1, wherein a diameter of the electrical lead is less than about 2 mm. 5. The system of claim 1, wherein the plurality of transducer contacts comprises at least about 8 transducer contacts. 6. The system of claim 1, wherein a distance between the control unit and the end of the lead is less than about 5 cm. 7. The system of claim 1, wherein the control unit is encapsulated with a material. 8. The system of claim 7, wherein the encapsulation with the material provides a hermetic seal. 9. The system of claim 1, wherein the plurality of the electrical output contacts are connected to the plurality of transducer contacts by a plurality of filaments, each filament having a diameter of less than about 0.150 mm. 10. The system of claim 1, wherein the electrical lead is implantable in a subject. 11. The system of claim 1, wherein the implantable device provides power to the control unit to energize the control unit. 12. The system of claim 1, wherein the plurality of transducer contacts are selected from the group consisting of electrode contacts, optical contacts, acoustic contacts, induction coil contacts, magnetic coil contacts, and combinations thereof. 13. A method of treating a condition in a subject, comprising: generating a first input signal from an implantable device;transmitting the first input signal from the implantable device to a control unit positioned in an electrical lead body comprising a first end and a plurality of transducer contacts in close proximity to the first end;generating a plurality of output signals based on the first input signal from the implantable device and on a control function of the control unit;transmitting the plurality of output signals from the control unit to the plurality of transducer contacts to provide a precise delivery of signals to a predetermined treatment site;transmitting at least one second input signal from the plurality of transducer contacts to the control unit; andmodulating at least one parameter of the plurality of output signals in response to the at least one second input signal from the plurality of transducer contacts. 14. The method of claim 13, further comprising recording the at least one second input signal from the plurality of transducer contacts. 15. The method of claim 13, wherein each of the plurality of transducer contacts performs the act of at least one of sensing, transmitting, stimulating, and inhibiting. 16. The method of claim 13, wherein the plurality of transducer contacts are selected from the group consisting of electrodes contacts, optical contacts, acoustic contacts, induction coil contacts, magnetic coil contacts, and combinations thereof. 17. The method of claim 13, further comprising energizing the control unit from the implantable device.
