摘要: A technique utilizes blocking members to resist contraction of expandables in wellbore environments. The technique comprises an expandable having a wall with a plurality of expandable cells. A plurality of blocking members cooperate with at least some of the cells to resist contraction of the expandable device once transitioned to a desired expanded state.
