Abstract

A method includes disabling a synchronization mechanism of a handheld device and disabling one or more hardware buttons on the handheld device. The method also includes removing user access to one or more settings on the handheld device. In addition, the method includes removing one or more system functions on the handheld device.

Claims

1. A method of converting a personal digital assistant (PDA) into a controller device for an implantable medical device, the PDA comprising an operating system, the method comprising:

installing a medical program on the PDA, the medical program allowing a user of the PDA to control operations of the implantable medical device; and

installing a securing program on the PDA such that the securing program is executed on the PDA whenever the PDA is reset;

wherein upon execution, the securing program is operable to modify the operating system of the PDA to secure the operating system to prevent interference with operations of the medical program by;

(i) disabling a synchronization mechanism of the PDA that automatically synchronizes data with one or several other computing devices;

(ii) changing operating system settings associated with hardware buttons of the PDA to prevent execution of previous operating system enabled functions associated with the hardware buttons;

(iii) modifying an operating system menu to remove user access to selected operating system settings that permit user modification of assignment of functions to the hardware buttons; and

(iv) disabling selected operating system enabled functions.

2. The method of claim 1 wherein the securing program is further operable to disable access to one or more applications packaged with the operating system.

3. The method of claim 1 wherein one of the applications to which access is disabled is an internet browser application.

4. A personal digital assistant (PDA) device adapted to control an implantable medical device, comprising:

an operating system;

a medical device program for providing a user interface to control operations of the implantable medical device; and

a securing program that is automatically executed whenever the PDA is reset;

wherein upon execution, the securing program is operable to modify the operating system of the PDA to secure the operating system to prevent interference with operations of the medical program by;

(i) disabling a synchronization mechanism of the PDA that automatically synchronizes data with one or several other computing devices;

(ii) changing operating system settings associated with hardware buttons of the PDA to prevent execution of previous operating system enabled functions associated with the hardware buttons;

(iii) modifying an operating system menu to remove user access to selected operating system settings that permit user modification of assignment of functions to the hardware buttons; and

(iv) disabling selected operating system enabled functions.

5. The PDA of claim 4 wherein the securing program is further operable to disable access to one or more applications packaged with the operating system.

6. The PDA of claim 4 wherein one of the applications to which access is disabled is an internet browser application.

7. The PDA of claim 4, wherein:

the one or more operating system settings comprise operating system settings for a buttons group and a today group in a settings menu on the PDA; and

the one or more system functions comprise a date function, a calendar function, an inbox function, an owner information function, and a task function from a today screen on the PDA.
