A method of upgrading a medical device (32) having a controller (48) that controls operation of the medical devices according to an operating routine executed by the controller (48). Upgrading the medical device (32) includes communicating an external device (34), such as a conventional computer, with the controller. An external access key is provided to the external device and compared to an internal access key provided by the medical device (32). Upgrading of the medical device (32) is enabled if the two access keys match. Upgrading includes modifying or rewriting the operating routine stored in the medical device (32). A medical device (32) manufacturer, supplier, or seller controls the distribution of the external access keys, thereby providing the ability to track the medical devices (32) being upgraded and the upgrade provided to that device.

L'invention concerne un procédé de mise à niveau d'un dispositif médical comportant une unité de commande qui agit sur le fonctionnement du dispositif médical selon une routine de fonctionnement exécutée par l'unité de commande. La mise à niveau du dispositif médical consiste à relier un dispositif externe, tel qu'un ordinateur classique, avec l'unité de commande. Une clé d'accès externe est fournie au dispositif externe et comparée à une clé d'accès interne fournie par le dispositif médical. La mise à niveau du dispositif médical est activée si les deux clés d'accès concordent. La mise à niveau implique la modification ou la réécriture de la routine de fonctionnement contenue dans le dispositif médical. Le fabriquant, le fournisseur ou le vendeur contrôle la distribution des clés d'accès externes de façon à permettre le suivi des dispositifs médicaux pendant la mise à niveaux ainsi que la mise à niveau offerte au dispositif.
