An implantable device used to monitor and maintain at least one physiologic function, which is capable of operating in the presence of damaging electromagnetic interference. The implantable device includes primary and secondary modules, each independently protected from EMI damage via at least one shielding and/or filtering, and a non-electrical communication device for communicating in at least one direction between the primary and the secondary modules. The primary module, in response to input from electrical sensing leads, activates the secondary module in a failsafe mode. In the failsafe mode, the secondary module carries out a physiologic function upon activation and in the presence of electromagnetic interference.

1. An implantable capable of operating in the presence fan electromagnetic interference, comprising:a primary module configured to operate in a normal operating mode in the absence of the electromagnetic interference;a secondary module, each one of the primary module and the secondary module being independently protected from damage due to the electromagnetic interference via at least one of a shielding and a filtering;a sensing lead coupled to the primary module; anda non-electrical communication device for communicating in at least one direction between the primary module and the secondary module,wherein the primary module, in response to an input from the sensing lead, activates, via the non-electrical communication device, the secondary module to operate in a failsafe mode, andwherein the secondary module carries out at least one physiologic function upon activation and in the presence of the electromagnetic interference. 2. An implantable device as in claim 1, wherein the implantable device returns to the normal operating mode from the failsafe mode upon a cessation of the electromagnetic interference. 3. An implantable device as in claim 1, wherein the shielding includes one of a non-magnetic metal, carbon, a carbon composite, and a combination thereof. 4. An implantable device as in claim 1, wherein the primary module includes an optical signal source for generating an optical signal and the no electrical communication device includes one of a transparent window and a port, and herein a communication provided by the non-electrical communication device, including the activation of the secondary module, is via the optical signal. 5. An implantable device as in claim 1, wherein the primary module includes at least one electrical circuit and the failsafe mode is effectuated by opening the at least one electrical circuit, so as to prevent an externally-applied electrical current from damaging the at least one electrical circuit. 6. An implantable device as in claim 1, wherein the at least one physiologic function is a cardiac assist function, and wherein the implantable device is a cardiac assist device. 7. An implantable device as in claim 6, wherein the implantable device is at least one of a pacemaker and a defibrillator. 8. An implantable device as in claim 6, wherein the shielding is one of a non-magnetic metal, a carbon, a carbon composite, and a combination thereof. 9. An implantable device as in claim 6, wherein the primary module includes an optical signal source for generating an optical signal and the non-electrical communication device for at least uni-directional communication is one of a transparent window and a port, and wherein a communication provided by the non-electrical commination device, including the activation of the secondary module, is via the optical signal. 10. An implantable device as in claim 6, wherein the primary module includes at least one electrical circuit and the failsafe mode is effectuated opening the at least one electrical circuit, so as to prevent an externally-applied electrical current from damaging the at least one electrical circuit.
