Neuromodulation Effectiveness
 Size- Is the lead small enough to go anywhere?
 Convenience- Is it possible to tunnel to the target?
 Complexity- Is a custom pulse generator required?
 Acuity- can effects be long term?
 Contact Positioning- can electrodes be positioned
to activate nerve bundles?
 Contact Geometry- can electrodes be designed to
optimize the field with safe charge density?
 Correlation- electrode location correct to provide
therapeutic relief?
 Pulse parameters- Pulse width, frequency,
waveform, bursts?
 Pulse Sequences- multichannel, variability, cross
talk?

NOT a BION® or Inductive
 Other wireless products utilizing coils need
coils externally
 Large external is difficult for the patient to
wear, limiting compliance
