Abstract: An electrical connection assembly of a medical device includes a plurality of electrical contact blocks and a sealing member, which are held within a cavity of a base of the assembly. The sealing member includes a plurality of openings, at least one interior surface surrounding a bore and at least one void. Each electrical contact block extends into a corresponding opening of the sealing member, and a conductive sidewall of each block defines a portion of a perimeter of an area for receiving a lead connector, while the bore of the sealing member forms another portion of the perimeter of the area. The at least one void provides a compressible space in a bulk volume of the sealing member. When the lead is inserted within the area, and a cap is engaged with the base, the at least one interior surface of the sealing member is compressed about the lead.

Abstract: An electrical connection assembly of a medical device includes at least one conductive sidewall mounted in a fixed position to a module base; the sidewall may be electrically coupled to a feedthrough wire. The assembly further includes at least one resilient member to apply a spring force against a connector element of a lead connector when the connector element is positioned adjacent to the conductive sidewall. The spring force of the resilient member causes electrical coupling between the connector element and the conductive sidewall.

Abstract: An improved connection system for coupling a device such as a pacemaker, cardioverter, defibrillator, nerve stimulator, muscle stimulator, implantable monitor or other medical device to a medical lead is disclosed. The connection system includes a coupling member designed to couple to the proximal end of the lead. This coupling member, which includes an inner lumen sized to form a press fit around the proximal end of the lead body, may be of a generally tubular construction. This coupling member includes connector means to enable a connector pin at the proximal end of the lead to mechanically and electrically couple to a device. The connector means may further include means for coupling both mechanically and electrically to a ring connector on the proximal end of a multi-polar lead. An insertion member may also be provided to allow the lead to be more easily inserted within the inner lumen of the coupling member.
