Interactive programmer for biomedical implantable devices

Abstract

A computer-controlled programmer having a user-interactive display is designed to control the parameters of a wide variety of implantable devices with different programming requirements. During programming, screen messages prompt the user to perform required actions by pressing lighted targets on the display screen. The programmer includes a console and a lightweight cable connected programming head. When the console is turned on, a self test routine automatically tests the programmer's batteries, memory banks and communications systems. For the communications test, the programmer employs a self-contained telemetry system which mimics the response of an implant. With certain implants, the programmer automatically changes programming options in response to information received from an implant as well as in response to selection of certain modes and lead configurations. The programmer software is designed to limit access to certain values and parameters which require the attendance of an authorized physician. Access to these non-routine programming functions is provided via a combination lock on the console. With implants having data telemetry, the programmer software is designed to confirm programming by comparing a stored replica of the originally transmitted programming data to an automatic echo of the programming data received by the implant.
