Study Summary

The investigators will investigate the device feasibility of human peripheral nerves and muscles recording and stimulation using percutaneous Utah Slanted Electrode Arrays (pUSEAs) implanted into residual peripheral arm nerves and EMG electrodes implanted in the residual muscles of patients with limb amputations in order to determine the ability of the HAPTIX (Hand Proprioception and Touch Interfaces) System to control an upper-extremity prosthesis, and to provide a sense of cutaneous touch and muscle proprioceptive feedback to the amputee.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
