FLUID FLOW IMPEDANCE SYSTEM

摘要

A fluid flow impedance system including a member having a wall with at least one opening therethrough and a tool positionable relative to the at least one opening. The tool has a carrier with an expandable material disposed therewith. The expandable material is operatively arranged to expand into the at least one opening, in response to the expandable material experiencing a predetermined condition, for impeding a flow of fluid through the at least one opening.
