Abstract
An endovascular navigation and positioning system including a transducer on a distal end of an endovascular instrument, a control system connected to the transducer, the control system being configured to generate and receive at least one acoustic signal using the transducer, a pre-processor containing computer-readable instructions for manipulating the acoustic signal input to extract information related to desired parameters, a processor configured to evaluate the parameters to generate an output related to guidance of the instrument, and an output device for displaying an indication of the output generated by the processor. The processor may evaluate the information using artificial intelligence including inference rules related to navigation state, comparisons to information in a database, and probabilities, among others. The system may use an electrical signal as a confirmation input. Further disclosed is a method of navigating and positioning an endovascular device in a vasculature.
