ABSTRACT:
An implantable prosthesis, such as an artificial cardiac pacer, or the like, is protected from misoperation caused by RF energy and/or electrostatic energy incident thereon by a protective device attached to the lead wire connecting the device to tissue stimulating electrodes or other such electrodes mounted in a patient. The protective device is the device disclosed in U.S. patent application Ser. Nos. 07/794,125, 07/584,045 and 07/866,512. The protective device includes a Ferrite body electrically and thermally connected to the lead wire and to a ground element, such as the housing for the prosthetic device. The Ferrite body, in conjunction with the lead and the ground element, has an impedance that exceeds the impedance established between the lead wire and ground when the device is exposed to RF energy.
