Abstract

Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to provide FFR measurements over a length of a vessel of interest in a small, compact device that integrates with existing proximal and distal pressure measurement systems and does not require a separate power source.

Description

technical field [0001] The present disclosure relates generally to the assessment of blood vessels, and in particular to the assessment of the severity of blockages or other restrictions to the flow of fluid through a blood vessel. In some instances, various aspects of the present disclosure are particularly suited for assessment of biological blood vessels. For example, some embodiments of the present disclosure are specifically configured for the assessment of narrowing of blood vessels in humans. Background technique [0002] One currently accepted technique for assessing the severity of stenosis in blood vessels, including ischemia leading to injury, is Fractional Flow Reserve (FFR). FFR is a calculation of the ratio of distal pressure measurements (taken on the distal side of the stenosis) to proximal pressure measurements (taken on the proximal side of the stenosis). FFR provides an index of stenosis severity that allows a determination of whether the blockage is res...
