The electrode leads are tunnelled subcutaneously to the implanted stimulator located in the pectoral region. Surgical procedures to enhance both voluntary and stimulated hand function are often performed in conjunction with stimulator implantation. Full approval was received in August,1997. More than 65 individuals with quadriplegia have received the implanted neuroprosthesis at more than a dozen different collaborating sites. Users have demonstrated the ability to grasp and release objects and to perform activities of daily living more independently when using the neuroprosthesis.
Individuals utilize the device at home on a regular basis.
