Implantable connector including at least one electrical component
An implantable connector for connecting an electronics package and a neural interface is made by way of a compressible contacts (e.g., a spring) that physical contacts a corresponding exposed bond pad. The compressible contact is held in compression with the exposed bond pad using a mechanical coupler. The compressible contact is physically separated and electrically isolated from other contacts by way of a compressible gasket. The compressible gasket is also held in compression using the mechanical coupler.
