Systems and methods for measuring pulse wave velocity with an intravascular device
First Claim
1. A method of measuring the velocity of a pulse wave, comprising:
- collecting pulse wave data with an intravascular device at a first location within a body lumen;
collecting pulse wave data with the intravascular device at a second location within the body lumen; and
calculating the velocity of the pulse wave in the region between the first and second locations with the pulse wave data collected at the first and second locations.

Abstract
The systems and methods described herein allow measurement of the velocity of a pulse wave propagating within a body lumen using an intravascular elongate medical device. The elongate medical device can include a data collection device configured to collect pulse wave data at a location within the lumen. The data collection device is communicatively coupled with a velocity measurement system and configured to output the collected data to the velocity measurement system. The velocity measurement system is configured to calculate the velocity of the pulse wave based on the collected data. The velocity of a pulse wave over a region of the lumen can be used for tissue characterization, diagnosis and the like.
