Methods, systems and devices for providing cardiac resynchronization therapy (CRT) to a patient using a leadless cardiac pacemaker and an extracardiac device. The extracardiac device is configured to analyze one or more QRS complexes of the patient's heart, determine whether fusion pacing is taking place, and, if not, to communicate with the leadless cardiac pacemaker to adjust intervals used in the CRT in order to generate desirable fusion of the pace and intrinsic signals. The extracardiac device may take the form of a subcutaneous implantable monitor, a subcutaneous implantable defibrillator, or other devices including wearable devices.

Cardiac resynchronization using fusion promotion for timing management

A system and method for confirming identity and authority by a patient medical device is provided. Master credentials are issued to a requesting device and a receiving device from an authorizing agent. The master credentials include a public key of the authorizing agent and a digital signature of a root certification authority. Device credentials are issued to the requesting device from the authorizing agent. The device credentials include a public key of the requesting device and a digital signature of the authorizing agent. Identification credentials are provided to the receiving device and include the device credentials and a digital signature of the requesting device. The requesting device is authenticated. The digital signature of the authorizing agent in the device credentials is checked using the public key of the authorizing agent in the master credentials of the receiving device. The digital signature of the requesting device in the identification credentials is checked using the public key of the requesting device in the device credentials.

The authorizing agent's digital signature in the device credentials is checked using the authorizing agent's public key in the master credentials of the receiving device. The requesting device's digital signature in the identification credentials is checked using the requesting device's public key in the device credentials.

A system and method for providing secure communication of sensitive information is provided. A crypto key unique to an implantable medical device is dynamically generated on a programmer. Sensitive information for the implantable medical device is encrypted using the crypto key. A telemetry connection of at least one of a short range and a long range is established between the implantable medical device and the programmer. The encrypted sensitive information is transmitted to the implantable medical device via the telemetry connection. The crypto key is transmitted to the implantable medical device via the telemetry connection at short range.

System and method for providing secure communication of sensitive information

A system and method for securely exchanging sensitive information with an implantable medical device is presented. A crypto key stored on an implantable medical device is retrieved by a programmer via a secure short range interface. Sensitive information is encrypted as sensitive data using the crypto key. The encrypted data is stored on the implantable medical device.

System and method for securely exchanging sensitive information with an implantable medical device

A system and method for securely authenticating a data exchange session with an implantable medical device is presented. A crypto key uniquely associated with an implantable medical device is defined to authenticate data during a data exchange session. A secure connection is established from an external source with a secure key repository securely maintaining the crypto key. Authorization to access data on the implantable medical device is authenticated by securely retrieving the crypto key from the secure key repository.

System and method for securely authenticating a data exchange session with an implantable medical device

Integrity of a wirelessly telemetered message communicated between an implantable medical device and an external programmer is authenticated by encoding the message. The message is encrypted based on a random number or time stamp and a secret key. The message is authenticated by encryption and decryption or by executing a hash function.

Cryptographic authentication for telemetry with an implantable medical device

A system and method for providing secure exchange of sensitive information with an implantable medical device is presented. A crypto key uniquely associated with an implantable medical device is defined to encrypt sensitive information during a data exchange session. The crypto key is securely obtained over a secure connection from a secure key repository securely maintaining the crypto key. The sensitive information is encrypted using the crypto key and the sensitive information is stored as encrypted data onto the implantable medical device.
