Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0036] like figure 1 As shown, a program control device that can update the internal firmware of a cardiac pacemaker includes an external program control instrument radio frequency transceiver device I, and a pacemaker telemetry circuit II for two-way data wireless transmission with the external program control instrument. Circuit II is bidirectionally connected with a microprocessor MCU; this microprocessor MCU can be any micro-power consumption processor that contains multi-channel analog-to-digital converter ADC and digital-to-analog converter DAC, and the present embodiment adopts TI's Msp430 microprocessor.

[0037] The telemetry circuit II on the upper left of the block diagram, when there is no program controller function, the pacemaker circuit is powered by the internal battery; when the program controller function and the radio frequency signal...

Abstract

This invention relates to a program control apparatus and method capable of updating inside solidification software of heart pacemaker, which comprises an external programmed-control RF receive / send device, a pacemaker remote measurement circuit with bidirectional wireless data transmission to the programmed-control device and bidirectional connected to a MPU that comprises a random access memory for running variable and data buffer and a ROM to rewrite program and divide into three storage zones, the programmed-control parameter zone with pacemaker default mode, running parameters and edition information; the main program zone for current control software of the pacemaker, and the bootstrap program zone to rewrite pacemaker main program. It also comprises a program to upgrade the pacemaker software acted on the remote measurement circuit by the RF field, and a bootstrap program stored in bootstrap program zone of pacemaker flash memory.

Description

technical field [0001] The invention relates to a program control system of an active implantable medical device, in particular to a program control system for rewriting or updating the internal firmware of an implantable cardiac pacemaker. Background technique [0002] Various active implant devices, such as implantable cardiac pacemakers, implantable cardiac defibrillators, implantable nerve stimulators and implantable drug delivery systems, have been widely used clinically, and their functions and classifications are becoming more and more more and more complicated. Taking pacemakers as an example, from the most basic single-chamber ventricular demand pacemaker (VVI) to the most complex intelligent dual-chamber frequency-responsive pacemaker (DDDR), there are many corresponding to different pacing modes and additional diagnostics The type of function to choose from. [0003] The choice of pacemaker type and the setting of pacing parameters are generally determined by do...
