This paper introduces a new type of modular neuroprosthesis called the Networked Neuroprosthesis (NNP). The NNP system is the first fully implanted modular neuroprosthesis that includes implantation of all power, signal processing, biopotential signal recording, and stimulating components. The system consists of a central "power module" (PM) with daisy chained "remote modules" to provide function through sensing and neuromodulation. The PM supplies power to the remote modules and manages communication both within the system and between the system and external interfaces. Two types of remote modules were developed: a four-channel pulse generator module (PG4) for stimulation and a two-channel biopotential recording module (BP2) for measuring muscle signals. This manuscript describes the design, benchtop testing, and first-in-human functionality of the first generation remote modules capable of stimulation (PG4) and biopotential recording (BP2).
The NNP system can restore functional capabilities for people with disabilities, such as spinal cord injury, stroke, cerebral palsy, and multiple sclerosis.
The modular design allows the system to be adapted to individual needs, facilitating improved quality of life for a greater number of people.
The network of sensors that can be incorporated into the system has potential for advanced stimulation control.
