Abstract
A vascular catheter assembly includes an over-the-wire stent deployment catheter and a flow-by-channel assembly. The stent deployment catheter is positioned just below the occluded artery in accordance with standard procedures. The flow-by-channel then shunts blood, and thus all friable plaque, from the high pressure carotid occlusion to the negative pressure extremity to effectively reverse the flow of blood through the occluded artery. The stent is then advanced into the narrowed artery and deployed. Thus, the vascular catheter assembly takes advantage of the collateral blood flow to solve the problem of stroke during endovascular procedures.
