Quantification of recruitment properties of multiple contact cuff electrodes
Warren M. Grill,J.T. Mortimer +1 more
TL;DR: Field steering currents improved selectivity as reflected by significant increases in the maximum torques that could be generated before spillover to other fascicles, significant increases between the difference between the current amplitude at spillover and theCurrent amplitude at threshold, and significant increase in the slope of the current distance relationship.
Journal ArticleDOI
The effect of stimulus pulse duration on selectivity of neural stimulation
Warren M. Grill,J.T. Mortimer +1 more
TL;DR: This study determined that shorter PW's allowed more spatially selective stimulation of nerve fibers and generated larger torques before spillover and created a larger dynamic range of currents between threshold and spillover.
Journal ArticleDOI
Neural and connective tissue response to long‐term implantation of multiple contact nerve cuff electrodes
Warren M. Grill,J.T. Mortimer +1 more
TL;DR: The incidence and characteristics of the morphological abnormalities at the cuff level are consistent with those observed in previous studies of nerve cuff electrodes, and support the hypothesis that spiral cuff electrodes can be implanted with an internal diameter less than that of the nerve and expand to accommodate the nerve without compression.

Implantable helical spiral cuff electrode
TL;DR: A self-curling elongate nonconductive sheet (A) defines a helical cuff electrode (10) as mentioned in this paper, and a plurality of contact members (40) are linearly disposed along a direction (C) between a first layer (30) and a second layer (32) of laminated elastomeric material.
Patent
Systems and methods for reversibly blocking nerve activity
TL;DR: In this article, a specific waveform is used that causes the nerve membrane to become incapable of transmitting an action potential, and the membrane is only affected underneath the electrode, and it is immediately and completely reversible.
