|Package Architecture and Component Design for an Implantable Peripheral Nerve Stimulation and Recording System for Advanced Prosthetics|
|Keywords: peripheral nerve, advanced prosthetics, implantable stimulation and recording system|
|One of the limitation of current prosthetic is the ability to provide sensory feedback to the human user. Due to this constraint, approximately 60-80 percent of amputees experience a phenomenon known as phantom limb pain, an ongoing painful sensations that to the individual, seems to be coming from the part of the limb that is no longer there. The lack of sensory feedback also limits the intuitive control of the user’s hand movement, i.e. sense of grip or position. To address these limitations, we created am implantable system that could provide peripheral nerve stimulation, recording and motor control . The architecture of our Sensory-Stimulation Lead (SSL) system consist of multiple satellites connected to Draper’s custom designed nerve electrodes. In this phase of the design, the implanted system is connected to an external controller via percutaneous connections. The active electronics of the satellite is enclosed in a hermetic package approximately 14mm in diameter and less than 5mm thick. A custom ceramic feedthrough substrate provides the electrical connections of the internal electronics board to both the nerve electrodes and percutaneous leads. In this paper, we will describe the various packaging components of the system and the design, fabrication, and assembly considerations that drove our technology choices.|
