Knitted Stent Unravels for Complete Removal from Patient

Stents are cylindrical mesh tubes that can be placed in arteries or in the lungs to open blockages or areas that are narrow or weak. Traditional stents work well, but one disadvantage is that they must remain in the body. Researchers from the Norwegian University of Science and Technology, Trondheim, Norway, are testing a removable stent that can be used in the lungs.
