CONNECTOR ASSEMBLIES WITH NOVEL SEAL FOR ELECTRICAL STIMULATION SYSTEMS AND METHODS OF MAKING AND USING SAME

A connector assembly includes an elongated connector housing and defines a port at one end of the connector housing for receiving a proximal end of a lead or lead extension; a lumen that extends from the port along at least a portion of the length of the connector housing; connector contacts axially spaced-apart and disposed along the lumen for coupling to a proximal end of a lead or lead extension; and non-conductive spacers disposed between adjacent connector contacts. Each of the spacers includes an outer tubular extension, an inner tubular extension, and a connection region coupling the outer tubular extension to the inner tubular extension. The inner tubular extension has a free end and the inner tubular extension is configured and arranged to form a seal against the proximal end of the lead or lead extension when inserted into the lumen.
