FLOW REGULATION VALVE FOR CONTROLLING INFLATION RATE OF A BALLOON DEPLOYING A SCAFFOLD

摘要

An apparatus and method for controlling inflation pressure, pressurization rate, and volumetric flow rate of a balloon during deployment of a stent or scaffold is disclosed. The apparatus includes a valve (200, 300) that has a flow restrictor (228, 328) that limits flow of inflation fluid into the balloon to a maximum value and provides essentially no resistance upon deflation of the baloon.
