Abstract
A method of navigating and positioning an endovascular device in a vasculature is disclosed. Initially, a system including an endovascular device and at least one transducer is inserted into the lumen of a patient. An acoustic signal is then transmitted within the lumen. A reflected signal is pre-processed to extract one or more acoustic features. The one or more acoustic features are processed using a computer readable set of rules to produce an output related to guidance of the instrument within a blood vessel or a position of the instrument within the blood vessel.
Claims20
A method of determining a position of a medical device in vasculature of a patient, the method comprising:
- receiving an electrical signal from an electrode on the medical device;
- extracting one or more ECG features from the electrical signal;
- calculating a first indicator score by inputting the one or more ECG features into a first indicator equation;
- calculating a second indicator score by inputting the one or more ECG features into a second indicator equation;
- identifying a positional state of the medical device by comparing the first and second indicator scores;
- and
- displaying an indicator on an output device indicating the positional state.
A non-transitory computer readable storage medium including a program configured to be executed by a processor to perform a method of determining a position of a medical device in vasculature of a patient, the method comprising:
- receiving an electrical signal from an electrode on the medical device;
- extracting one or more ECG features from the electrical signal;
- calculating a first indicator score by inputting the one or more ECG features into a first indicator equation;
- calculating a second indicator score by inputting the one or more ECG features into a second indicator equation;
- identifying a positional state of the medical device by comparing the first and second indicator scores;
- and
- displaying an indicator on an output device indicating the positional state.
A system configured to determine a position of a medical device in vasculature of a patient, the system comprising:
- a pre-processor configured to:
- receive an electrical signal from an electrode on the medical device, and
- extract one or more ECG features from the electrical signal
- a processor configured to:
- receive the one or more extracted ECG features from the pre-processor,
- calculate a first indicator score by inputting the one or more ECG features into a first indicator equation,
- calculate a second indicator score by inputting the one or more ECG features into a second indicator equation, and
- identify a positional state of the medical device by comparing the first and second indicator scores;
- and
- an output device configured to display an indicator indicating the positional state.
