Patents by Inventor David M. Steinhaus

David M. Steinhaus has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200397962
    Abstract: The disclosure describes systems and techniques for detection of pump thrombosis in mechanical circulatory support (MCS) devices. An example pump thrombosis detection system includes a transducer and processing circuitry. The transducer may be configured to generate a signal representative of a mechanical wave from a mechanical circulatory support device. The processing circuitry is communicatively coupled to the transducer. The processing circuitry may be configured to determine an indication of pump thrombosis based on the signal and, based on the indication of pump thrombosis, control the pump thrombosis detection system to at least one of generate an alert or initiate an intervention.
    Type: Application

  • Patent number: 9750943
    Abstract: An implantable medical device includes an activity sensor, a pulse generator, and a control module. The control module is configured to determine an activity metric from the activity sensor signal over an activity metric interval and compare the activity metric to a loss of capture detection threshold. The control module may detect loss of capture in response to the activity metric being less than the loss of capture detection threshold and increase a pacing pulse output in response to detecting the loss of capture.
