  • Leadless pacemaker and method for storing event data in a leadless pacemaker
    Patent number: 11583681
    Abstract: A leadless pacemaker, and method for storing event data therein, comprising a central processing unit, a first logic circuit configured to generate event data based on a first event occurring during operation of the leadless pacemaker, a first hardware event counter configured to be incremented if specific event data are generated by said first logic circuit, a first memory unit comprising a first bit configured to be set if said first hardware event counter is incremented to a first maximum number of counts, a second memory unit communicating with said first memory unit, wherein said central processing unit is configured to transfer said first bit to said second memory unit, a first RAM event counter in a random access memory of said leadless pacemaker, wherein said central processing unit is configured to increment said first RAM event counter if said first bit is transferred to the second memory unit.

  • Intra-cardiac communications using ultrasound to provide direct timing information without electrical interferences
    Patent number: 11219771
    Abstract: A medical system contains a first implantable device and a second implantable device. Each implantable device contains a communication unit configured to transmit an ultrasonic signal to the communication unit of another implantable device of the medical system. The first implantable device is configured to periodically transmit a broadcast message to at least the second implantable device using the communication unit of the first implantable device.
