Abstract

In a method and a system for organizing not yet implanted implantable medical devices, each having a telemetry unit associated therewith, a local administration unit transmits an inquiry signal to at least one of the telemetry units and receives a return signal therefrom in response to the inquiry signal. The return signal establishes the existence of the medical device, and the local administration unit, or a remote external unit in communication with the local administration unit, can then determine a course of action to be taken, such as a recall procedure, invoicing or taking inventory, based on the return signal from the medical device.

Claims

1. A method for organizing not yet implanted implantable medical devices each having a telemetry unit associated therewith, comprising the steps of:

wirelessly transmitting a first inquiry signal from a local administration unit to the telemetry unit associated with one of said not yet implanted medical devices;

wirelessly transmitting a return signal, in response to said first inquiry signal, from said telemetry unit of said one of said not yet implanted medical devices to said local administration unit and thereby informing said local administration unit of the existence of said one of said not yet implanted medical devices;

supplying a second inquiry signal to said local administration unit containing identity information for a not yet implanted implantable medical device;

in said local administration unit, matching said identity information in said second inquiry signal with an identity of said at least one not yet implanted medical device; and

determining a pre-implantation action to be taken for said one of said medical devices as a result of said matching.

2. A method as claimed in claim 1 comprising:

generating said second inquiry signal in an external unit remote from said local administration unit and including an inquiry requirement in said second inquiry signal, and supplying said second inquiry signal from said external unit to said local administration unit;

in said local administration unit, generating said first inquiry signal dependent on said second inquiry signal, and including said inquiry requirement in said first inquiry signal;

in said return signal, including a response to said inquiry requirement; and

forwarding said response to said inquiry requirement from said local administration unit to said external unit.

3. A method as claimed in claim 2 comprising:

storing device data for each of a plurality of not yet implanted implantable medical devices in a central data storage accessible by said external unit; and

generating said second inquiry signal in said external unit dependent on said device data for one of said not yet implanted medical devices.

4. A method as claimed in claim 2 comprising:

entering patient data into said external unit designating a patient specific parameter for a candidate patient of a not yet implanted implantable medical device; and

generating said second inquiry signal in said external unit dependent on said patient data.

5. A method as claimed in claim 4 wherein the step of entering said patient data comprises storing patient data for a plurality of patients in a central data storage accessible by said external unit, and retrieving patient data for said candidate patient from said central data storage.

6. A method as claimed in claim 2 comprising generating said second inquiry signal in said external unit as a part of a recall procedure for said one not yet implanted medical device.

7. A method as claimed in claim 2 comprising generating said second inquiry signal in said external unit as a part of a invoicing procedure for said one not yet implanted medical device.

8. A computer readable medium encoded with a data structure for organizing not yet implanted implantable medical devices each having a telemetry unit associated therewith, said data structure programming a local administration unit to:

wirelessly transmit a first inquiry signal from the local administration unit to the telemetry unit associated with one of said not yet implanted medical devices;

wirelessly receive a return signal, in response to said first inquiry signal, from said telemetry unit of said one of said medical devices at said local administration unit and thereby informing said local administration unit of the existence of said one of said not yet implanted medical devices;

receive a second inquiry signal at said local administration unit containing identity information for a not yet implanted implantable medical device;

match said identification unit in said second inquiry signal with an identity of said at least one not yet implanted medical device; and

determine a pre-implantation action to be taken for said one of said not yet implanted medical devices as a result of said matching.

9. A system for organizing not yet implanted implantable medical devices, comprising:

a plurality of not yet implanted implantable medical devices, each having a telemetry unit associated therewith;

a local administration unit having a wireless interface for communicating with each of said telemetry units, said local administration unit wirelessly transmitting a first inquiry signal to one of said medical devices via the telemetry unit associated therewith, and receiving a return signal in response thereto from said one of said not yet implanted medical devices, thereby establishing existence of said one of said not yet implanted medical devices in said local administration unit;

a remote external unit in communication with said local administration unit, said external unit communicating a second inquiry signal from said external unit to said local administration unit containing identity information for a not yet implanted medical device;

said local administration unit matching said identity information to said existence of said one of said not yet implanted medical devices; and

said external unit determining a pre-implantation action to be taken for said one of said not yet implanted medical devices dependent on said matching in said local administration unit.

10. A system as claimed in claim 9 comprising:

a central data storage, accessible by said external unit, containing device data for a plurality of not yet implanted medical devices;

said external unit retrieving said device data from said central data storage and including said device data in said second inquiry signal;

said local administration unit generating said first inquiry signal dependent on said device data in said second inquiry signal and generating a further return signal, dependent on said return signal from said telemetry unit associated with said one of said not yet implanted medical devices, and communicating said further return signal to said external unit.

11. A system as claimed in claim 10 wherein said telemetry unit is contained in said one of said medical devices.

12. A system as claimed in claim 10 comprising an indicator unit connected to said one of said not yet implanted medical devices, said indicator unit generating a local indication signal upon generation of said return signal.

13.
