Claim Text:
1. A sliding sleeve opening with a deployed plug, the sleeve comprising: a housing defining a first bore and defining a flow port communicating the first bore outside the housing; an inner sleeve defining a second bore and being movable axially from a closed position to an opened position inside the first bore relative to the flow port, the second bore having a shoulder disposed therein; a movable ring disposed in a first axial position in the second bore; and a deformable ring disposed in the second bore between the shoulder and the movable ring, the movable ring engaging the deployed plug and moving the inner sleeve open with the deployed plug in response to initial fluid pressure applied against the engaged plug, the movable ring moving axially in the inner sleeve with the deployed plug toward a second axial position adjacent the shoulder in response to subsequent fluid pressure applied against the engaged plug, the deformable ring deforming in response to the movement of the movable ring toward the shoulder and engaging the deployed plug when deformed.
