ABSTRACT:
A medical device providing a flexible hardware platform to support alternative therapeutic functions is disclosed. In one embodiment, a microprocessor-based pacemaker incorporates a non-volatile ferroelectric random access read/write memory (FRAM) for storing microprocessor instructions defining a pacing algorithm. Information in the FRAM may be re-written after implant of the pacemaker in a patient via the pacemaker's telemetry link, so that the pacemaker's pacing function may be upgraded or replaced without explant of the pacemaker. The non-volatility of the FRAM ensures that the pacing function is not erased if power to the pacemaker is momentarily interrupted. The flexible hardware platform allows a single type of pacemaker to be implanted in patients with varying cardiac conditions and pacing requirements, thus reducing the inventory requirements of hospitals. The pacing function in pacemakers for patients with progressive or otherwise changing medical conditions can be modified in accordance with the patients' changing needs without invasive procedures. Rewriting of the pacing function is carried out separately from conventional modification of mode selection and parameter value programming. Other information, including parameter data, implant data, patient medical data, and device identification data may also be stored in the FRAM.
