Abstract
Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a collapsible seat disposed within the bore. The seat has a first position defining a first seat inner diameter when the apparatus is in the run-in position and a second position defining a second seat inner diameter when the apparatus is in the set position. The first seat inner diameter is greater than the second seat inner diameter. A plug element is adapted to be disposed into the bore and landed on the seat to move the seat from the first position to the second position. While in the second position, the seat restricts fluid flow through the bore and provides additional support to the plug member landed on the seat.
