Patent ID: 7798862

Claim:
An electrical connection assembly for a medical device, the assembly for coupling the device to a medical electrical lead connector that includes a plurality of connector elements spaced apart from one another along a length of a proximal portion of a medical electrical lead, and the assembly comprising: a base for mounting to a housing of the device, the base including a cavity; a cap engagable with the base; a bore for receiving insertion of the medical electrical lead connector therein; a plurality of electrical contact blocks held within the cavity, each of the plurality of electrical contact blocks including a conductive sidewall, the conductive sidewalls defining a portion of a perimeter of the bore and being spaced apart from one another along a length of the bore such that each is located for electrical coupling with a corresponding connector element of the lead connector, when the lead connector is inserted within the bore; and a sealing member held within the base cavity, the sealing member including a plurality of openings, at least one interior surface surrounding the bore, to define another portion of the perimeter of the bore, and at least one void; wherein each of the plurality of electrical contact blocks extends into a corresponding opening of the plurality of openings of the sealing member; the at least one void of the sealing member is independent of the bore and of the plurality of openings and provides a compressible space in a bulk volume of the sealing member; and when the lead connector is inserted within the bore and the cap is engaged with the base, the at least one void is compressed and the at least one interior surface of the sealing member is compressed about the lead connector.
