Abstract
A system for treating a body lumen including a first stent configured to be positioned in a body lumen and a second stent configured to be positioned in the lumen of the first stent prior to removing the first stent from the body lumen. The first stent includes a liner disposed radially inward of the tubular scaffold of the first stent to permit tissue ingrowth within a tissue ingrowth region defined between the liner and the tubular scaffold. The retrieval stent is configured to be expanded within the previously implanted first stent to cause tissue to recede from the tissue ingrowth region to facilitate removal of the first stent from the body lumen.
