Medical devices include stimulation and/or sensing circuitry that is interconnected to electrical components by a flexible circuit body having exposed portions of circuit traces that are attached to electrical contacts of the electrical components. Each circuit trace may span a separate window formed in an insulative body of the flexible circuit body, or a plurality of circuit traces may span a single window or may be freely extending from the insulative body. The exposed portion of the circuit trace may be plated with a conductive metal and then attached to the electrical contact of the electrical component. The flexible circuit body may be an extension from a flexible electrical circuit board containing the circuit. The circuit may be present on a circuit board that includes electrical contacts and where the flexible circuit body has exposed portions of circuit traces attached to the electrical contacts of the circuit board.

A medical device is electrically connected to a biological tissue for transmission of an electrical signal between the medical device and the biological tissue. The medical device includes a housing assembly and a control circuit assembly that controls the electrical signal. The control circuit assembly is enclosed within the housing assembly, and the control circuit assembly includes an electrically conductive terminal. The device further includes an electrical component at least partially enclosed within the housing assembly. The electrical component has a connecting member that electrically connects the electrical component to the control circuit assembly. The connecting member is resistance welded and bonded directly to the electrically conductive terminal of the control circuit assembly.
