Interventions

  • percutaneous Utah Slanted Electrode Arrays (pUSEAs) — DEVICE
    Microelectrode slanted arrays with a large number of electrodes will be surgically implanted into peripheral nerves of patients with limb amputations.

Study Details

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.

Arms

  • Experimental: Implantation of a percutaneous Utah Slanted Electrode Arrays (pUSEAs)
    The arm (s) of the patient which has been amputated. Intervention include insertion of the percutaneous Utah Slanted Electrode Arrays which will interact with nerve endings in order to gain knowledge about device feasibility and nerve stimulation.

Primary Outcome Measure
