Abstract

An implantable medical device (IMD) may include a communication module, a therapy control module, a firmware control module, and a service application. The communication module is configured to wirelessly communicate over an RF link with an external device. The therapy control module is configured to deliver therapy to the patient, and may include a reprogrammable therapy logic circuit configured to operate the therapy control module in a reprogrammable mode of operation, and base-therapy state machine (BTSM) logic circuit configured to operate the therapy control module in a base therapy mode of operation. The firmware control module may include CPU and a memory. The service application may be stored in the memory. The firmware control module is configured to launch the service application, and the BTSM logic circuit provides a base level of sensing and pacing therapy while the communications module in parallel maintains the RF link with the external device.
