Abstract
A communication device (CD) exchanges messages with an implantable infusion pump via telemetry such that commands are supplied thereto and operational information is obtained therefrom. The CD is controlled, at least in part, by a processor IC according to a software program operating therein and provides feedback to a user via a visual display, an audio alarm, and a vibrational alarm, and allows input from the user via a touch sensitive keypad. Certain input functions are restricted by password. The visual display includes an icon and fixed element display region and a bitmap display region. The fixed element display region includes time and date displays, battery and drug level displays that decrement, and a moving delivery state display. Various screens allow operational or log information to be displayed and/or user entry of commands. Program features when disabled are removed from a series of screen options that can be scrolled through.

11. An external communication device for an implantable medical device, the external communication device comprising:
-
a device housing;
an antenna coupled to the housing;
wireless telemetry circuitry, within the housing, that communicates with the implantable medical device via the antenna;
a display, within the housing, that presents information;
a backlight that illuminates the display; and
control circuitry that disables the backlight during activation of the telemetry circuitry to reduce electrical interference. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method comprising:
-
activating wireless telemetry circuitry in an external communication device to communicate with an implantable medical device, wherein the external communication device includes an internal antenna, and the telemetry circuitry receives signals from the implantable medical device via the internal antenna during activation of the telemetry circuitry;
disabling an electroluminescent backlight of a liquid crystal display in the external communication device during activation of the telemetry circuitry to reduce electrical interference in response to a telemetry quiet mode signal; and
enabling the backlight when the telemetry is not activated.
