Abstract
An arterial access device has an internal lumen and a proximal port, the arterial access device sized and shaped to be inserted directly into an arterial access site in the common carotid artery such that the lumen provides a passageway for an interventional device to be inserted via the proximal port into the carotid artery. The arterial access device has a distal portion that is configured to be inserted into an arterial pathway through the access site, and a proximal portion configured to extend outward from the access site when the distal portion is in the arterial pathway.

1-20. (canceled)
An inner member comprising an elongate flexible catheter body defining a single lumen extending between a proximal opening and a distal opening to facilitate placement over a guidewire,
- wherein the elongate flexible catheter body comprises variable flexibility and made from softer materials at a distal section and harder materials towards more proximal sections,
- wherein a distal end region of the elongate flexible catheter body comprises a first outer diameter and a second outer diameter, wherein the first outer diameter of the elongate flexible catheter body is sized and shaped to correspond to an internal lumen of an interventional distal catheter through which the inner member extends, and wherein the second outer diameter is located along a substantially uniform microcatheter tip portion distal to the first outer diameter and is smaller than the first outer diameter, and
- wherein an inner diameter of the single lumen of the elongate flexible catheter body extending through the distal end region and extending through the microcatheter tip corresponds to an outer diameter of the guidewire.
