Grill – also the company’s chief scientific officer – has developed a fourth dimension, enabling clinicians to control what he calls the temporal pattern of stimulation, or the pattern of time between the pulses. Using computer models and engineering methods, he design patterns of stimulation, like Morse code, that maintain the device’s efficacy while making it more efficient. Deep Brain Innovations, then, thinks it can use that technique to improve the longevity of implanted DBS devices and reduce replacement-related risks and costs.DBS devices comprises electrodes, leads and a pulse generator that are implanted in patients. They deliver electrical pulses to targeted areas of the brain to block electrical nerve signals that generate PD symptoms like tremor, stiffness, slowed movement and walking problems. Clinicians program a “dose” of therapy by selecting the amplitude of stimulation delivered, the duration of the pulse and the frequency of stimulation.
