Abstract
Systems and method for delivering and deploying an expandable stent to treat Intracranial atherosclerotic disease (ICAD) involving large and medium-sized blood vessels. The disclosed systems include a catheter, a shaft comprising a distal end disposed within the catheter, an expandable stent comprising a proximal end and a distal end, wherein the shaft is coupled to the expandable stent and the shaft is disposed within the expandable stent, and a plurality of struts, wherein a first end of each strut is coupled to the shaft and a second end of each strut is coupled to the expandable stent. Longitudinal movement of the shaft relative to the expandable stent extends the plurality of struts radially outward and expands the expandable stent, similar to umbrella. The plurality of struts provides radial force to the expandable stent in an expanded configuration to the vessel walls of the patient.
