High-density percutaneous chronic connector for neural prosthetics

A high density percutaneous chronic connector, comprising:

• a first connector structure having an array of magnets surrounding a mounting cavity and means for attaching the first connector structure to a subject;
• a first electrical feedthrough array seated in the mounting cavity of the first connector structure and having a bottom side for connecting to a percutaneously connected device;
• a second connector structure haying an array of magnets surrounding a mounting cavity;
• a second electrical feedthrough array seated in the mounting cavity of the second structure and having a top side for connecting to external electronics;
• and
• a feedthough interconnect matrix positioned between a top side of the first electrical feedthrough array and a bottom side of the second electrical feedthrough array, and having a plurality of electrically conductive wires arranged in a dielectric substrate to electrically connect the first electrical feedthrough array to the second electrical feedthrough array;
• and
• wherein the two arrays of magnets are arranged to attract in a first angular position to connect the first and second connector structures together and electrically connect the percutaneously connected device to the external electronics, and to repel in a second angular position to facilitate removal of the second connector structure from the first connector structure.
