Abstract
Described are methods for performing a medical procedure at a treatment site in a cerebral vessel of a patient. The methods include positioning a system of devices into an advancement configuration, the system including a catheter and an inner member sized and shaped to slide within the catheter lumen. The inner member defines a single lumen and has a distal portion, the distal portion having a first outer diameter that tapers distally to a second outer diameter that is smaller than the first outer diameter. When positioned in the advancement configuration, the inner member extends coaxially through the catheter lumen and the distal portion of the inner member is positioned distal to the distal end of the catheter. The method further includes advancing the system of devices distal to a petrous portion of an internal carotid artery while the system of devices is positioned in the advancement configuration.
