Zero insertion force percutaneous connector and flexible brain probe assembly

Abstract

A percutaneous connector comprises a female-half that includes a housing that has a pair of side walls, each having an interior surface. An electrical contact assembly is arranged along the interior surface of at least one of the side walls and has a set of first electrical contacts. Insulating material electrically isolates the electrical contacts from one another. In addition, an electrical conductor attached to each electrical contact extends outside of the housing. A male-half includes a sheet of resilient material, bent into a U-shape and having two opposed outer surfaces. A handle assembly is adapted to permit a user to squeeze the two opposed outer surfaces closer to each other. In addition, a set of second contacts is attached to at least one of the outer surfaces and is arranged in matching configuration to the first set of contacts. Insulating material electrically isolates the contacts from one another. With this design, a user can grasp the male-half by the handle assembly, squeeze together the two outer surfaces, place the male-half in the female-half and release the handle assembly so that the male set of contacts touches the female set of contacts. Additionally, a method of producing an electrode probe assembly, comprising, providing a flexible polymer substrate bearing a conductive material plating and using photolithography and electroplating to form a set of contacts and conductors on the flexible polymer substrate.
