covered stent
Stent device with synthetic membrane covering designed to seal perforations or exclude aneurysms from circulation.
Full Definition
A covered stent, also known as a stent-graft, consists of a metallic stent framework covered with a synthetic membrane material such as PTFE or polyurethane. These devices are primarily used to treat vessel perforations, pseudoaneurysms, or to exclude true aneurysms from circulation while maintaining vessel patency. The covering material provides immediate sealing but may increase thrombogenicity and requires careful anticoagulation management.
Usage
Usage note: Distinguish from drug-eluting stents which have pharmaceutical coatings, not membrane coverings.
