Patent ID: 7601033

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 comprising: a plurality of conductive members positioned along the connector bore and electrically coupled to the plurality of traces, each of the conductive members having a main body portion and a flange portion, the conductive member flange portion having a lower surface facing inwardly toward the bore opening and an opposing upper surface; and a plurality of sealing members, each sealing member being positioned between conductive members, each of the plurality of sealing members having a main body portion and a flange portion, and each of the sealing members defining an inner surface establishing a fluid-resistant interface with the lead connector assembly of a medical electrical lead and an outer surface establishing a fluid-resistant interface with the inner surface of the shell, wherein the body portion of each of the plurality of sealing members includes an inner sealing ring protruding radially from the sealing member inner surface and establishing an interference fit with a lead connector assembly inserted into the bore of the stacked subsassembly, wherein the flange portion of each of the plurality of sealing members includes an outer sealing ring protruding radially from the sealing member outer surface and establishing an interference fit with the inner surface of the shell connector bore without axial compression of the sealing member when the stacked subassembly is placed within the connector bore, 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 conductive member flange portion, such that compressive force exerted on the outer sealing ring due to the interference fit established upon the stacked subassembly being placed within the connector bore does not subject the sealing member body portion or the inner sealing rings to a distorting force.
