Abstract: The disclosure describes devices and systems that include a grounding electrode. In one example, a system may include a first module including a pulse generator within a first housing, a second module comprising a switch matrix within a second housing distinct from the first housing, a connecting cable that connects the first module to the second module, a grounding electrode disposed distal of the first module and proximal of the second module, and a plurality of electrodes disposed distal of the second module, wherein each electrode of the plurality of electrodes are selectively coupled to the pulse generator via the switch matrix. These devices or system can be used to provide neurostimulation and/or neurorecording.

Abstract: This document discusses, among other things, a lead body extending longitudinally along a lead axis, a driver axially displaceable relative to the lead body, and a driven member coupled to the lead body and displaceable away from the lead axis. The driven member at least partially defines an expandable passage having at least one internal dimension. The driver is displaceable into the expandable passage and has at least one outer dimension that is larger than the at least one internal dimension of the expandable passage. An example method includes disposing a first member having a first cross-section in a lead assembly having a lead axis, an expandable passage, and a displaceable member proximate the expandable passage. The method further includes urging the first member into the expandable passage in the lead assembly, and urging the displaceable member away from the lead axis to expand the expandable passage.
