SYSTEM FOR INCREASING TOTAL DIAMETER AND LUMEN DIAMETER OF PERIPHERAL VEIN SO AS TO FORM ARTERIOVENOUS FISTULA OR ARTERIOVENOUS GRAFT, OR SYSTEM TO BE USED BEFORE FORMING ARTERIOVENOUS FISTULA OR ARTERIOVENOUS GRAFT

摘要

PROBLEM TO BE SOLVED: To provide a system for increasing a lumen diameter and a total diameter of a peripheral vein in a sustained manner.SOLUTION: There is provided a system 10 and method for increasing blood velocity and wall shear stress (WSS) of a peripheral vein over a sufficient period so as to increase a total diameter and a lumen diameter of the peripheral vein 30 in a sustained manner. The method includes pumping of blood by desired flow velocity and pulsation. To optimize the velocity and extent of the peripheral vein expansion, monitoring and adjustment of the pumping are performed as needed so that desired blood velocity, WSS, and pulsation in the peripheral vein are maintained.SELECTED DRAWING: Figure 1B
