the at least one feature of the housing comprises a center projection having an outer wall;

the corresponding feature of the screw-head comprises the screw-head cavity;

the center projection mates with the screw-head cavity through one of: a threaded engagement between the outer wall of the center projection and one or more inner walls of the cavity, and a friction fit between the outer wall of the projection and one or more inner walls of the cavity.

3. The neuromodulation device of claim 2 , wherein:

the at least one feature of the housing comprises a pair of opposed side projections defining a housing cavity;

the corresponding feature of the screw-head comprises the screw-head itself;

the screw-head mates with the housing cavity through one of: a threaded engagement between the outer wall of the screw-head and one or more inner walls of the opposed side projections, and a friction fit between the outer wall of the screw-head and one or more inner walls of the opposed side projections.

4. The neuromodulation device of claim 3 , wherein the therapy module comprises a therapy-module interface structure configured to couple with the lead interface structure.

5. The neuromodulation device of claim 4 , wherein the therapy-module interface structure comprises a dongle having at least one in-line connector configured to mate with a corresponding connector of the lead interface structure.

6. The neuromodulation device of claim 4 , wherein the housing comprises an upper region, and the therapy-module interface structure comprises a plurality of electrical contacts exposed at the upper region and configured to mate with a corresponding plurality of electrical contacts of the lead interface structure.

7. The neuromodulation device of claim 1 , wherein the housing comprises a groove formed in a pliable surface of the housing, the groove configured to receive a portion of the lead body and secure the portion in place through a friction fit.

8. A pain management system comprising:

a spinal stabilization device comprising a rod, a plurality of pedicle screws each having a screw-head defining a screw-head cavity configured to receive a portion of the rod, and a corresponding plurality of inserts configured to engage with the inner wall of the cavity to secure the rod in place in the cavity; and

a neuromodulation device comprising a therapy module comprising electronics packaged within a housing having a form factor comprising at least one feature configured to mate with a corresponding feature of the screw-head of one of the plurality of pedicle screws, wherein the respective features mate in a manner that enables the therapy module to mechanically couple to and subsequently decouple from the screw-head of the pedicle screw.

9. The pain management system of claim 8 , further comprising an implantable medical lead comprising a ribbon structure having a plurality of electrodes and a lead interface structure configured to mechanically and electrically couple to and subsequently decouple from the therapy module.

10. The pain management system of claim 8 , further comprising an implantable medical lead comprising:

a ribbon structure having a first side and a second side opposite the first side;

a plurality of first electrodes associated with the first side and arranged in a first pattern; and

a plurality of second electrodes associated with the second side and arranged in a second pattern;

wherein the ribbon structure is configured to transition from a planar state to a non-planar state upon the application of a force and to remain in the non-planar state upon removal of the force.

11. A method of implanting a pain management system that includes spinal stabilization hardware and a neuromodulation device having a therapy module configured to mechanically couple to and decouple from a component of the spinal stabilization hardware, the method comprising:

creating direct access to nerve structures while implanting the spinal stabilization hardware during a spinal fusion procedure;
