Abstract:
A device for use during carotid angioplasty or stenting comprising:a guide catheter having proximal and distal ends, and a lumen extending therebetween; a tubular member slidably disposed within the lumen of the guide catheter, the tubular member having first and second proximal ports, a distal end formed from a fluid impermeable material that defines a drainage port, and a lumen extending between the first and second proximal ports and the drainage port, the tubular member having a retracted position wherein the distal end is disposed within the guide catheter and has a retracted diameter suitable for endoluminal insertion, and an extended position, wherein the distal end of the tubular member extends beyond the distal end of the guide catheter and self-expands to an expanded diameter adapted to occlude antegrade blood flow in a vessel, the distal end having a non-folding edge that lies flush against the vessel to prevent the accumulation of emboli thereagainst; and a hemostatic valve disposed on the first proximal port for controlling the flow of blood therethrough.
