Abstract
An interventional catheter is adapted for treating a blood vessel. In an embodiment, the catheter includes an elongate shaft sized for insertion in a blood vessel and a stent positioned on a distal region of the elongate shaft. An expandable dilation member is coupled to a distal region of the elongate shaft. The expandable dilation member is adapted to expand outward. A stent containment member is positioned over the elongate shaft and the stent to contain the stent in a collapsed state.

91. A method of treating a blood vessel, comprising:
-
transcervically inserting a catheter system into a carotid artery, the catheter system 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; and retracting the stent containment member from the elongate shaft to withdraw the stent containment member from the distal section and into the proximal extension proximal to the connector. - View Dependent Claims (92, 93, 94, 95, 96, 97, 98, 99, 100)
