To provide an improved system and a method for treating combined presence of clots and stenosis in a cerebral vasculature.SOLUTION: A design capable of both mechanical thrombectomy and stenting for treating occlusions in a cerebral vasculature provides a three-catheter setup. A first outer catheter has a largest diameter and can serve as a guide catheter while also being a sheath for the other catheters. A second deployment catheter can be configured for aspiration of occlusions and can include a stepped or recessed section proximal to a distal tip that can act as a housing for a braided expandable stent. The outer diameter of this stepped section can be lined with an inflation device on top of which the braided stent sits. Internal to the second deployment catheter is a microcatheter which can deliver mechanical thrombectomy devices to a target site to retrieve an occlusion in a vessel, after which the stent can be expanded and implanted in the vessel.SELECTED DRAWING: Figure 1A
