Patent ID: 7988497

Claim:
An implantable medical device connector assembly adapted for receiving a medical electrical lead having a lead connector assembly, comprising: a molded, insulative shell having an inner surface forming a connector bore, a circuit member including a plurality of conductive traces extending through the shell; and a stacked subassembly positioned along the connector bore, the stacked subassembly having a bore opening adapted to receive a lead connector assembly, the stacked subassembly comprising: a plurality of conductive members positioned along the connector bore and electrically coupled to the plurality of traces, each of the conductive members comprising a flange portion having an upper surface facing toward the shell inner surface; and a plurality of sealing members, each sealing member being positioned between conductive members and having a main body portion, an outer surface and a flange portion forming a portion of the outer surface, the flange portion establishing a fluid-resistant interface with the inner surface of the shell, each of the sealing members defining an inner surface establishing a fluid-resistant interface with the lead connector assembly; wherein the flange portion of each sealing member overlaps the flange portion of an adjacent conductive member so as to be internally supported from underneath by the upper surface of the conductive member flange portion, and wherein each of the plurality of sealing members further comprise an outer sealing ring protruding radially from the sealing member outer surface along the sealing member flange portion.
