Abstract

A downhole apparatus comprises a tubular body including a seat, and an actuating member including a wiper dart and an extrudeable portion adapted to mate with the seat. When a first pressure is applied across the member a function may be performed. Application of a higher second pressure causes the portion to be extruded through the seat.
