MRI-resistant implantable device
First Claim
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; and
a 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, and wherein the secondary module carries out at least one physiologic function upon activation and in the presence of the electromagnetic interference.

Abstract
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.
