Abstract
An apparatus comprising an implantable acoustic transducer, an acoustic transducer interface circuit communicatively coupled to the acoustic transducer, and a controller circuit communicatively coupled to the acoustic transducer interface circuit. The controller is configured to, in response to receiving an indication of a patient condition associated with a development of a blood vessel obstruction, initiate delivery of acoustic energy that mitigates the blood vessel obstruction. Other systems and methods are described.
Claims25
Apparatus comprising:
- an acoustic transducer configured to be implanted in a thoracic blood vessel or heart;
- an acoustic transducer interface circuit communicatively coupled to the acoustic transducer;
- and
- a controller circuit, communicatively coupled to the acoustic transducer interface circuit, wherein the controller is configured to:
- enable detection of a patient condition by initiating application of acoustic energy by the transducer at a first frequency;
- and
- in response to receiving an indication of the patient condition, cause the transducer to initiate delivery of acoustic energy at a second frequency configured to mitigate the blood vessel obstruction.
4 more elements
A method comprising:
- applying acoustic energy to thoracic cardiovascular tissue of a patient at a first frequency to detect a patient condition associated with a development of a blood vessel obstruction using an implantable medical device (IMD);
- receiving an indication of the patient condition into the IMD;
- and
- applying, in response to receiving the indication of the patient condition, acoustic energy at a second frequency to mitigate the blood vessel obstruction using the IMD.
