Abstract
Devices, systems and methods are disclosed for determining the composition of a plaque at a plaque site, which could be inside a blood vessel. Through a combination of fluid injection with different conductivities and measurement of the resultant conductances, a parallel tissue conductance measure is obtained that assists in determining the composition of the site plaque. Lower parallel conductance levels are determinative of a higher lipid and/or fatty plaque, which is a type that may break out of its position and cause organ injury or death.
