<p>A connector block (122) providing electrical coupling to electronic componentry (24) of an implantable medical device (10). The implantable medical device (10) has a case (38) containing the electronic componentry (24). A reformed electrically conductive "wireform" (126) mounted with respect to a structurally rigid polymer frame (124) forming a plurality of electrical contacts. Potting is formed in situ with liquid thermoset polymer substantially filling any voids in the connector block (122) and forming a thermoset polymer gasket between the connector block (122) and the case (38).</p>
