Abstract

A sterilizable programmer repeater system for retransmission of a programmed code via an RF data link from a pacemaker or defibrillator programmer to an implanted pacemaker or defibrillator which can be used in the operating theater. Coded program information from a remotely placed programmer is data linked by an RF transmitter to a programmer repeater placed externally adjacent to an implanted pacemaker or defibrillator. The received coded program data information is rebroadcast by a transmitter in the programmer repeater to the implanted pacemaker or defibrillator. Coded program data information from the implanted pacemaker or defibrillator is also sent in the reverse direction from the implanted device to the remotely linked placed programmer.

Claims

1. A wireless programmer/repeater system for communicating with an implanted medical device in a patient comprising:

programmer means positioned remote from the patient for providing programming data to be communicated to the medical device; and

repeater means physically separate from and not connected to the programmer means and positioned proximite to the patient for relaying the programming data from the programmer means to the medical device.

2. The wireless programmer/repeater system of claim 1 wherein the repeater means comprises:

first antenna means for communicating with the programmer means; and

second antenna means for communicating with the medical device.

3. The wireless programmer/repeater system of claim 2 wherein the repeater means includes means for generating the program data in a first and a second code format and the first antenna means transmits and receives according to the first code format and the second antenna means transmits and receives according to the second code format.

4. The wireless programmer/repeater system of claim 1 wherein the repeater means is contained in a nonconductive enclosure.

5. The wireless programmer/repeater system of claim 1 wherein the repeater means is contained within an enclosure that is sterilizable and can be used in a sterile environment separate from and not physically connected to the programmer means.

6. The wireless programmer/repeater system of claim 1 further comprising radio frequency (RF) signal generation means for relaying the programming data between the programmer means and the repeater means in the form of radio frequency (RF) signals.

7. The wireless programmer/repeater system of claim 1 further comprising infrared signal generation means for relaying the programming data between the programmer means and the repeater means in the form of infrared signals.

8. The wireless programmer/repeater system of claim 1 further comprising ultrasonic signal generation means for relaying the programming data between the programmer means and the repeater means in the form of ultrasonic signals.

9. A wireless programmer/repeater system for communicating with an implanted medical device in a patient comprising:

programmer means positioned remote from the patient for indirectly sending data to and receiving data from the medical device; and

repeater means physically separate from and not connected to the programmer means and positioned proximite to the patient for relaying data between the programmer means and the medical device,

10. The wireless programmer/repeater system of claim 9 wherein the repeater means comprises:

first antenna means for communicating with the programmer means; and

second antenna means for communicating with the medical device.

11. The wireless programmer/repeater system of claim 10 wherein the repeater means includes means for generating the program data in a first and a second code format and the first antenna means transmits and receives according to the first code format and the second antenna means transmits and receives according to the second code format.

12. The wireless programmer/repeater system of claim 9 wherein the repeater means is contained in a nonconductive enclosure.

13. The wireless programmer/repeater system of claim 9 wherein the repeater means is contained within an enclosure that is sterilizable and can be used in a sterile environment separate from and not physically connected to the programmer means.

14. The wireless programmer/repeater system of claim 9 further comprising radio frequency (RF) signal generation means for relaying the programming data between the programmer means and the repeater means in the form of radio frequency (RF) signals.

15. The wireless programmer/repeater system of claim 9 further comprising infrared signal generation means for relaying the programming data between the programmer means and the repeater means in the form of infrared signals.

16. The wireless programmer/repeater system of claim 9 further comprising ultrasonic signal generation means for relaying the programming data between the programmer means and the repeater means in the form of ultrasonic signals.
