Claim:
1. An interventional catheter system for treating a blood vessel, comprising: an access sheath positionable transcervically in a carotid artery, the access sheath comprising a distal section forming part of a reverse flow path of an embolic protection system, a proximal extension outside of the reverse flow path and connected to the distal section by a connector; an elongate shaft sized for insertion through the access sheath positioned transcervically in the carotid artery; a self-expanding stent positioned on a distal region of the elongate shaft; a retractable stent containment member slidably positioned over the elongate shaft and the stent to contain the stent in a collapsed state, wherein the retractable stent containment member is configured to be retracted from the elongate shaft a first length of the distal region exposing the self-expanding stent and wherein the stent containment member is longer than the elongate shaft; a control mechanism on a proximal region of the elongate shaft, wherein the control mechanism is coupled to the stent containment member and can be used to retract the stent containment member; and a flow shunt fluidly connected to the access sheath and forming a part of the reverse flow path of the embolic protection system, wherein the flow shunt comprises two or more parallel flow paths and a valve to open or close one or more of the parallel flow paths selectively directing blood flow through the one or more of the parallel flow paths to adjust a state of flow through the flow shunt, wherein retraction of the stent containment member from the elongate shaft the first length withdraws the stent containment member from the distal section of the access sheath and into the proximal extension proximal to the connector.
