METHOD TO INCREASE LONGEVITY & EFFICACY IN NEURAL ARRAYS

Physicians increasingly use neural arrays as therapeutic treatment for
neurological disorders despite their shortcomings. Neural arrays are
limited by functional efficiency and longevity concerns, cause glial scar
tissue to develop and encapsulate the implant, which inhibits electrical
signal stimulation, and degrade over time due to the growing impedance
barrier that requires increased charge flow to stimulate an action
potential.

Researchers at the University of Utah have developed an electrode with a
platinum coating that addresses many of these shortcomings. The
electrode has a highly biocompatible, pseudoporous electrode-tissue
interface and a modified texture that increases its real surface area. The
invention requires less electrical signal to successfully stimulate neuron
action potentials, which decreases risk to surrounding neural tissue and
increases longevity of the array. In vitro testing indicated the modified
texture also reduced neural scar tissue surrounding the array.
