Claim:
1. An actuating apparatus comprising: a wellbore tubular having at least one flow path between an exterior of the wellbore tubular and an interior of the wellbore tubular; a sleeve disposed within a wellbore tubular, wherein the sleeve is configured to longitudinally translate along the wellbore tubular interior between a first position preventing fluid flow through the at least one flow path and a second position allowing fluid flow through the at least one flow path; at least one actuable member, wherein at least one actuable member engages the sleeve and the wellbore tubular; and a deformable seat engaged to the sleeve, wherein the deformable seat is configured to form a sealing engagement with a driving member, and wherein a first pressure is applied to the driving member on the deformable seat to release the at least one actuable member and translate the sleeve from the first position to the second position, and wherein the deformable seat is configured to deform in response to a second pressure applied by the driving member on the deformable seat to permit the driving member to pass through the deformable seat, the second pressure being higher than the first pressure.
