Handheld patient programmer for implantable human tissue stimulator
First Claim
1. A portable patient programmer for an implanted device, said programmer comprising:
- a main housing, configured to be held in a user'"'"'s hand;
a battery, disposed within said housing;
a plurality of user key, disposed on said main housing;
at least one visual indicator, disposed within said main housing and visible from outside said main housing;
an audio indicator, disposed within said main housing and audible from outside said main housing;
a telemetry receiver circuit, disposed within said housing and operative to receive uplink telemetry signals from said implanted device;
a telemetry transmitter circuit, disposed within said housing, for transmitting said downlink operational command and parameter signals to said implanted device;
a control circuit, disposed in said main housing and coupled to said user key, said visual indicators, said audio indicator, and said battery, said control circuit responsive to actuation of each of said key to control said transmitter circuit to transmit a predetermined one of said command and parameter signals to said implanted device wherein said control circuit is further responsive to continuous depression of one of said plurality of keys for longer than a first predetermined period of time during which none of said uplink signals is received by said receiver circuit to disable said transmitter circuit until said at least one key has been released.

Abstract
A patient programmer for facilitating patient control over an implanted medical device, such as an implanted spinal cord stimulator or the like, is disclosed. A programmer in accordance with the present invention is a portable, light-weight, easy to use patient programmer. The programmer enables a patient to control the operation of his or her implanted device outside of a clinical setting. The programmer incorporates features which ensure that users of varying ages, education levels, dexterity levels, physical and mental health will be able to safely control the operation of their implanted devices, within predefined limits established by a physician or clinician. Circuitry is provided for avoiding battery depletion and/or undesired programmer/implanted device communication in the event that the programmer'"'"'s key is accidentally depressed (for example, due to being jammed into a purse or pocket) or is depressed repeatedly or continuously over an extended period of time. The programmer provides tactile, audible, and visible feedback to the user to convey information regarding the proper (or improper) operation of the programmer and the implanted device. In one embodiment, the device includes a beeper and light-emitting diodes (LEDs) to indicate, for example, that a desired programming function has been successful or unsuccessful.

12. A method of controlling a portable patient programmer for an implanted device, the programmer having a main housing configured to be held in a user'"'"'s hand, a battery disposed within the housing, at least one user key disposed on the main housing, a telemetry receiver circuit disposed within the housing and operative to receive uplink telemetry signals from the implanted device, a telemetry transmitter circuit disposed within the housing for transmitting downlink operational command and parameter signals to the implanted device, a control circuit disposed in the main housing and coupled to the at least one user key and the battery, the method comprising the steps of:
-
a) actuating a user key;
b) transmitting a predetermined one of the command and parameter signals to the implanted device in response to step a);
c) continuously actuating the user key in step a) for longer than a first predetermined period of time during which none of the uplink signals from the implanted device are received by the receiver circuit to disable the transmitter circuit until the user key in step a) has ceased to be actuated. - View Dependent Claims (13, 14, 15)
