Abstract
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.
Claims20
An orifice insertion device configured to be inserted into an orifice and connecting conduit, the orifice insertion device comprising:
- a stent;
- and
- a plurality of sealing elements where each sealing element is operatively attached to the stent, wherein 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 and surrounding conduit sufficient to seal the conduit wall without appreciable deformation of the conduit wall,
- wherein the two sealing elements are formed from different materials, and
- wherein a further one of the plurality of sealing elements is configured to seal an opening of the conduit.
An orifice insertion device comprising:
- a stent;
- and
- a plurality of sealing elements where each sealing element is operatively attached to the stent, wherein two sealing elements of the plurality of sealing elements include an expandable section configured to be disposed within a canal and to exert a pressure on a canal wall sufficient to seal the canal,
- wherein the two sealing elements are formed from different materials, and
- wherein a further one of the plurality of sealing elements is configured to seal an opening of the canal.
An orifice insertion device comprising:
- a stent;
- and
- a plurality of sealing elements where each sealing element is operatively attached to the stent, wherein two sealing elements of the plurality of sealing elements include an expandable section configured to be disposed within an volume that traverses from an orifice to another orifice and exerts a pressure on a wall within the area sufficient to seal the volume,
- wherein the two sealing elements are formed from different materials, and
- wherein a further one of the plurality of sealing elements is configured to seal an opening of the volume.
