Medical implant software systems and methods

A method for remotely updating a medical device, comprising:

• providing build information to a build machine;
• receiving cryptographic key information and a key path;
• creating, by the build machine, a medical device update;
• receiving, by a server, companion device information, wherein the companion device is associated with the medical device;
• sending, from a key management system to the build machine, cryptographic certificate information;
• certifying and encrypting the medical device update, with the cryptographic key information;
• transmitting the encrypted medical device update, the key path, and companion device information to the server;
• sending a notification to a patient-facing application from the server, wherein the patient-facing application is accessed by the companion device;
• performing over the air update operations;
• downloading the encrypted medical device update from the server to the patient-facing application;
• updating the patient-facing application's cryptographic material using the key path;
• transmitting the medical device update from the companion device to the medical device;
• decrypting the encrypted medical device update on the medical device;
• and
• validating the medical device update on the medical device.
