Abstract

An implantable medical device (IMD) includes a connector header for making electrical and mechanical connections with a proximal connector assembly of an electrical medical lead and includes a retainer for retaining a penetrable grommet within a header grommet aperture. A connector block disposed within a header body of the connector header has a threaded bore aligned with a header grommet aperture and a connector block bore aligned with a header connector bore. The penetrable grommet is disposed within the header grommet aperture, and a setscrew is threaded into the threaded bore having a setscrew socket disposed to be engaged by a tool inserted through the penetrable grommet within the header grommet aperture to enable rotation of the setscrew within the threaded bore to tighten the setscrew against or to loosen the setscrew from a lead connector element received in the header connector bore.
