  • Publication number: 20230301535
    Abstract: This invention is related to artificial intelligent (AI) system with biodegradable endovascular nanoscale-structured flowmeter layer for monitoring cerebral blood flow during mental performance, blood flow through in-stent re-stenosis (ISR) and thromboembolism. The invention is based on blood flow inducing changes in magnetization of nanoscale microwave ferrites. These changes in magnetization, then interact with the microwave in a frequency-dependent manner using a microprocessor for processing and transmission via cellular phone network to human-machine interface for control of computers, machines or weapon systems. It detects reduction of blood flow through ISR and microembolic signals due to thromboembolism of the vessel much earlier before severe symptoms develop.

  • Publication number: 20230158311
    Abstract: The present invention provides monitoring of brain blood circulation in a patient with cardiac pacemaker for the prevention of symptoms associated with pacemaker syndrome and stroke. The monitoring of brain blood flow velocity is performed using a transcranial Doppler ultrasound device synchronized with an implanted cardiac pacemaker, to select the pacing mode that enhances cerebral perfusion in the patient. The system further detects microembolic signals in the cerebral circulation and triggers sonothrombolysis as well as release of thromolytic and neuroprotective agents for clot dissolution.

  • Patent number: 8282559
    Abstract: The present invention provides a method for monitoring long-term potentiation and long-term depression, comprising placing a subject in head down bed rest position and monitoring in real-time cerebral mean blood flow velocity using a transcranial Doppler device during psychophysiologic tasks. The method involves using Fourier analysis of mean blood flow velocity data to derive spectral density peaks of cortical and subcortical processes. The effect of head-down bed rest at different time intervals is seen as accentuation of the cortical peaks in long-term potentiation and attenuation of subcortical peaks in long-term depression, relative to baseline. The effect of different interventions could be evaluated for research, diagnosis, rehabilitation and therapeutic use.
