System and method for assessing hemodialysis arteriovenous fistula maturation

摘要

The present invention relates to the assessment of arteriovenous (AV) fistula maturation using a guidewire that measures intraluminal blood flow and / or pressure. The present invention provides a method for assessing AV maturation using an instrumented guidewire to measure intraluminal blood flow and / or pressure. By using a small diameter guidewire that does not substantially interfere with the flow, an accurate measurement that is useful for identifying when the sputum has matured and is therefore ready to be used for hemodialysis Can be done. Blood flow through the heel is measured using a guide wire, and the measured flow and / or pressure of blood is used to determine whether the heel is mature.
