Abstract
A medical device system includes a cardiac electrical stimulation device and a ventricular assist device (VAD). The cardiac stimulation device and the VAD are capable of communication with each other to confirm detection of cardiac events.
Claims20
A system comprising:
- a blood pump comprising a motor, an inflow cannula for receiving blood from a patient's heart, and a flow outlet for coupling to a patient's artery;
- a controller comprising a power source, a processor and a telemetry circuit configured for communication with a second device;
- and
- a drive line coupled between the blood pump and the controller for transmitting a drive signal to the blood pump;
- wherein the controller is configured to:
- estimate a flow rate of the blood pump;
- detect a cardiac event from the estimated flow rate;
- and
- control the telemetry circuit to transmit a request signal to the second device in response to detecting the cardiac event.
6 more elements
A method comprising:
- estimating a flow rate of a blood pump;
- detecting a cardiac event from the estimated flow rate;
- and
- transmitting a request signal to a second device in response to detecting the cardiac event.
1 more element
A non-transitory, computer readable medium comprising a set of instructions which, when executed by a processor of a medical device, cause the medical device to:
- estimate a flow rate of a blood pump;
- detect a cardiac event from the estimated flow rate;
- and
- transmit a request signal to a second device in response to detecting the cardiac event.
