Abstract

A system and methods for the automatic update of the software of an external programmer implant is that is used to program and configure an active implantable medical device implant and acquire data obtained by the implant. The programmer comprises software composed of an assembly of software objects. The implant comprises a memory containing parametric data for the functioning of the implant and an assembly of software objects necessary for the functioning of the programmer in connection with the aforementioned of parametric data. The programmer and the implant communicate bi-directionally. The automatic updating preferably occurs by the programmer reading of the memory of the implant, establishing a list of objects that are found in the implant with their respective versions, comparing the list to the objects (and their versions) that are in the programmer software, downloading from the implant of those objects which are not found in the programmer software and adding these objects to the programmer software; and/or downloading from the implant those objects in the programmer software whose version is prior to the version of the object found in the implant, and to replace the programmer software objects, with the more current version.

the programmer further comprises means for commanding the downloading from the implant of at least a part of said at least one software object contained in the implant memory and storing in said programmer memory the downloaded part of said software object.

2. The system of the claim 1, in which the programmer further comprises:

means for reading a list of software objects in said implant;

means for establishing a list of software objects read;

means for comparing said established list and the software objects of the software stored in the programmer memory;

means for identifying as an absent software object an object in said established list and not in said programmer software,

wherein the means for downloading downloads from the implant an identified absent object and adds the absent objects to the software in the programmer memory.

3. The system of claim 1 which wherein each implant software object has an associated version code corresponding to a date, and the programmer further comprises:

means for reading the memory of the implant and establishing a list of implant software objects and associated version codes;

means for comparing the established list to the programmer software objects and identifying a newer software object as an implant software object having a version code that is newer than the corresponding programmer software object; and

means for downloading from the implant the identified newer software and replacing said downloaded newer software object for the corresponding programmer software object.

4. The system of claim 3 wherein the programmer further comprises means for comparing said established list to the programmer software objects and identifying an absent software object as an object in said established list and not in said programmer software, and

wherein the downloading means further comprises means for adding said absent software object to the programmer software.

5. The system of claim 1 wherein each implant software object further comprises an identifying object, an identifying version and a block of program instructions and the programmer means for downloading downloads the block of program instructions for execution in connection with said parametric data, thereby updating said programmer for operation with said implant.

6. The system of claim 1 wherein said implant further comprises means for detecting a cardiac frequency of a patient and said at least one implant software object further comprises an object to display a nominal frequency for a cardiac pacemaker, wherein the programmer means for downloading downloads said display object and the programmer further comprises a display, and means for executing said downloaded display object to display the nominal cardiac frequency of said implant.

7. The system of claim 1 wherein said implant further comprises means for detecting a cardiac frequency of a patient over time and said at least one implant software object further comprises an object to display a cardiac frequency over a time measure, wherein the programmer means for downloading downloads said display object and the programmer further comprises a display, and means for executing said downloaded display object to display the cardiac frequency over time detected by said implant.

8. An active implantable medical device implant having a predetermined function comprising:

a memory,

a software program in said memory, and

parametric data for the functioning of the implant,

means for establishing a bidirectional information exchange with an external programmer including an antenna and means responsive to an external command from an external programmer for downloading information in said implant memory to said external programmer;

wherein the software further comprises at least one software object for the functioning of a programmer in connection with programming the parametric data of said implant, said at least one object being downloadable to an external programmer.

9. The implant of claim 8 wherein each software object stored in said implant memory further comprises an associated version code corresponding to a date.

10. The implant of claim 8 wherein the software stored in said implant memory further comprises a list of each downloadable software object in said implant.

11. The implant of claim 10 wherein each software object stored in said implant memory further comprises an associated version code corresponding to a date, wherein said list further comprises said version code for each software object.

12. An external programmer for use with an active implantable medical device implant, comprising:

a software, having at least one software object;

bi-directional information exchange connection by selective transfer from the implant to the programmer, of a datum of the functioning of the implant and a software object necessary for the functioning of a programmer in connection with the aforementioned implant; and

means for downloading from the implant of at least a part of said at least one software object and storing said downloaded software object as part of the programmer software.

13. The programmer of claim 12, in which the means for downloading further comprises

means for reading the memory of the implant;

means for establishing a list of objects found in said implant memory with their respective version code;

means for comparing the established list to at least one of the objects of the programmer software and determining whether or not the at least one object is absent from the list and, if not absent, determining whether the at least one object is a version prior to the object version in said programmer memory, and

means for commanding the downloading from the implant of the determined absent objects of the programmer software and to add these objects to the programmer software, and

means for commanding the downloading from the implant of the determined objects present in programmer software but whose version is prior to the one found in the implant, and to replace these objects in the programmer software.

14. The programmer of claim 12, in which each software object further comprises at least an identifying object, an identifying version and a block of program instructions, wherein the means for downloading said at least a part of said at least one software object downloads and stores in said programmer memory said block of program instructions and said identifying versions for said block of program instructions.
