Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A connector system for an electrical lead of a body implantable device, comprising a connector block having an electrical connection to a sensor encased in a fluid-impervious material; a first opening in the connector block adapted to receive an electrical conductor; a second threaded opening in the connector block intersecting the first opening; a threaded set screw in said second opening; said set screw having an outer end and an inner end; a resilient screw plug closing the outer end of the second opening; said screw plug having an outer end of an inner end; and a viscous, fluid-impervious material between the outer end of the set screw and the inner end of the screw plug.
Claim 2
Dependent Claim
