Systems and methods for evaluating hemodialysis arteriovenous fistula maturation
The invention relates to evaluation of maturity of arteriovenous (AV) fistula using guidewires that measure intravascular blood flow and/or pressure. The invention provides methods of evaluating AV fistula maturation using an instrumented guidewire to measure intravascular flow and/or pressure. By using a small diameter guidewire that does not interfere substantially with the flow, an accurate measurement can be made that is useful for identifying when a fistula is mature and therefore ready to be used for hemodialysis. The flow of blood through the fistula is measured using the guidewire and the measured flow and/or pressure of blood is used to determine if the fistula is mature.

Intravascular devices, systems, and methods are disclosed. In some embodiments, an intravascular pressure measurement device is provided. The intravascular device includes a flexible elongate member with a proximal portion and a distal portion and a lumen extending therethrough. The lumen is configured to allow the passage of a guidewire. The distal portion of the member includes first and second distal sections. The second distal section having an outer diameter that is smaller than the outer diameter of the first distal section. The intravascular device further includes a first pressure sensor disposed within the wall of the first distal section of the flexible elongate member to measure the pressure within the lumen.
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 assess the severity of a stenosis in the coronary arteries by monitoring fluid flow. In some embodiments, the devices, systems, and methods of the present disclosure include a flow-sensing element within a distal portion of an intravascular device that is mounted at an oblique angle with respect to a central longitudinal axis of the intravascular device. The angled flow-sensing element can be oriented away from a vessel wall and towards the center of the vessel lumen through rotation of the intravascular device.
