A terminal is provided for introducing signals from an electrical terminal pin in a heart pacemaker to a terminal lead introduced into a patient\s body. The terminal pin is disposed in a lid of the heart pacemaker so that the terminal pin is insulated from the lid. Means are also provided for introducing the signals on the terminal pin to the terminal lead without subjecting the pin to undue stresses. The terminal includes a hollow, electrically conductive ferrule disposed in concentric relationship with the terminal pin. The ferrule is provided with a flange which is disposed against the lid. An electrical filter is disposed in the ferrule and means are provided for maintaining the filter in fixed relationship to the ferrule and the terminal. Insulating means are provided for bonding the ferrule and the terminal. An inductance may also be included in the terminal and may be connected to the filter to enhance the filtering effect. An insulating bead is disposed on the ferrule and is bonded to the ferrule to transfer stresses on the terminal pin to the bead and ferrule. The insulating bead supports an electrically conductive catheter block which fits over the electrical terminal pin and communicates electrically with the terminal pin. The catheter block also holds the terminal lead in fixed position and communicates electrically with the lead and directs the lead into the body of the patient.
