DEVICES AND METHODS FOR DETERMINING PULSE WAVE VELOCITY BASED ON CHANGES IN VESSEL DIAMETER

摘要

Devices, systems and methods for pulse wave velocity determination in a renal artery are disclosed. An intravascular system may be included with two or more sensors disposed a certain distance apart on a flexible, elongate member. The sensors may be configured to measure changes in measurement value of the renal artery, such as the diameter of the renal artery and/or a distance between the sensors and the vessel walls, with pulse waves moving through the renal arter. The difference in the time at which the sensors measure these changes and the distance between the sensors may be used to calculate pulse wave velocity.
