Abstract: Embodiments of the invention include an implantable medical device having a digital signal processing circuit associated with an implantable medical device function. The digital signal processing circuit can be selectively implementable according to the clinical need of a patient. Embodiments of the invention also include methods of making and using such implantable medical devices.

Abstract: The invention is directed to implantable medical devices (IMDS) with dual-memory support. An IMD is designed to detect the presence or absence of a programmable non-volatile memory, such as flash memory. The IMD processor determines whether operation instructions reside in non-programmable non-volatile memory or in programmable non-volatile memory as a function of an output from a detector circuit.

Abstract: A battery/capacitor assembly for use in an implantable medical device comprises a battery and at least one capacitor housed in a unitary metal encasement. Either the battery, capacitor, or both may be coated with an insulating layer (e.g. plastic). In addition, a metallic layer may be disposed between the battery and the at least one capacitor.

Abstract: The invention is directed to techniques in which magnetic resonance imaging (MRI) is coordinated with the operation of an implantable medical device (IMD). By using an IMD to sense conditions, MRI can be improved because the sensed conditions can accurately define timing for application of electromagnetic radiation bursts. Moreover, by applying stimulation pulses specifically to coordinate the electromagnetic radiation bursts, the MRI may also be improved.

Abstract: The invention is directed techniques for coordinating telemetry of medical devices with magnetic resonance imaging (MRI) techniques. By coordinating telemetry of a medical device with the performance of MRI techniques with, the use of telemetry during MRI may be facilitated. In one example, information indicative of electromagnetic radiation bursts in MRI techniques can be communicated to the medical device prior to execution. In another example, the medical device may identify the electromagnetic radiation bursts, e.g., by measuring for the presence of such bursts. In either case, the medical device can adjust its telemetry to improve communication during MRI.
