Abstract

Techniques and systems for using spectroscopy, and/or image-based sensing with an intravascular blood pump are provided. The techniques generally include capturing a spectral response to light of a measured tissue and/or blood. Based on the specific needs, the method may include, e.g., determining a type of the measured tissue based on the spectral response, determining if the type of the measured tissue matches a target tissue type, determining a health of the measured tissue based on the spectral response, determining a treatment plan based on the health of the measured tissue, determining a type and/or quantity of components and/or characteristics in the blood, and/or determining a degree of heart recovery based on the type and/or quantity of the components and/or characteristics in the blood.

Dependent claims

A system, comprising:

an intravascular blood pump;
a sensor disposed in or on the intravascular blood pump, the sensor being operably coupled to one or more processors, a light source, and a spectrometer;
a non-transitory computer-readable storage medium containing instructions that, when executed by the one or more processors, causes the system to:
pass a light from the light source through the sensor towards a tissue to be measured within a patient's vasculature;
sense, using the spectrometer, a spectral response of light of the measured tissue captured by the sensor;
determine a type of the measured tissue based on the spectral response;
determine if the type of the measured tissue matches a target tissue type;
indicate to a user when the type matches the target tissue type;
determine a distance from the intravascular blood pump to the measured tissue having the target tissue type;
and
determine if the distance from the intravascular blood pump to the measured tissue having the target tissue type matches a target distance.
