EXPANDABLE SEALING DEVICES AND METHODS

摘要

An orifice insertion device includes a stent and a plurality of sealing elements where each sealing element is operatively attached to the stent. Two sealing elements of the plurality of sealing elements include an expandable section configured to be disposed within the orifice and to exert a pressure on an orifice wall sufficient to seal the orifice without appreciable deformation of the orifice wall. The two sealing elements are formed from different materials and a further one of the plurality of sealing elements is configured to seal an opening of the orifice. Other embodiments are disclosed.
