Implantable medical device with hardware-based patch
First Claim
1. A programmable logic device (PLD) implanted in an implantable medical device (IMD) wherein a microcomputer circuit integrates the PLD with a base processor of the IMD, the microcomputer circuit comprising:
- a PLD connected to a bus in the base processor;
a plurality of system clocks; and
a memory bank including I/O;
said PLD being operable to store downloaded software from an external programmer device to thereby reprogram the IMD in cooperation with said plurality of system clocks and said memory bank including I/O.

Abstract
An implantable medical device is provided which provides for more flexibility in re-programming of the control software, or program, which is controlling the functionality of an implanted pacemaker. The system comprises an external programmer device, which is capable both of programming the implanted device in a conventional way, and also downloading new control software to the implanted device. The downloaded software is programmed into a PLD integrated into the microprocessor, I/O, memory, and a clock control system via a standard data bus. The PLD may be configured to modify the function of the microprocessor, system I/O, random logic, and/or firmware function. The system enables increased processing capabilities, speed, flexibility, and attenuation of battery current drain.
