1 Las Vegas, NV 4-Dec-10 Emarit Ranu MSEE MSBS, Ewan Gillespie MBA, Kerry Bradley MS Boston Scientific Neuromodulation Valencia, CA USA The Benefits of Tight Contact Spacing: Computational Model on Avoiding Stimulation Gaps

2 Modeling: E. Ranu. Modeling based on: Rattay, F, “Analysis of models for extracellular fiber stimulation,” IEEE Trans Biomed Eng., Jul;36(7):676-82, 1989. (mV/cm 2 ) Maps the change in potential on the nerve. A function of position relative to electrode. Shows the level depolarization and hyperpolarization. Any depolarization above threshold causes neurons to fire. Activating Function: Contact Distance

7 Tight Contact Spacing: Rolling Cathodes Modeling based on: Rattay, F, “Analysis of models for extracellular fiber stimulation,” IEEE Trans Biomed Eng., Jul;36(7):676-82, 1989. Modeling: E. Ranu.

8 Wide Contact Spacing: Rolling Cathodes Modeling based on: Rattay, F, “Analysis of models for extracellular fiber stimulation,” IEEE Trans Biomed Eng., Jul;36(7):676-82, 1989. Modeling: E. Ranu.

9 The Benefits of Tight Contact Spacing Modeling based on: Rattay, F, “Analysis of models for extracellular fiber stimulation,” IEEE Trans Biomed Eng., Jul;36(7):676-82, 1989. Tight Continuous Wide Discontinuities Modeling: E. Ranu.
