Abstract
Apparatuses for restricting fluid flow through a well conduit comprise a tubular member having a seat member disposed within the tubular member for receiving a plug element. One or both of the seat member or the plug element comprise at least one shape-memory material to facilitate the plug element being able to land on the seat and/or to facilitate the plug element to pass through a seat member or other restriction in the tubular member either before or after landing on a seat.
