1. An interventional catheter for treating an artery, comprising:
an elongated body adapted to be inserted into a common carotid artery via an access location such that the elongated body can be navigated distally to an artery in a brain through the common carotid artery via the access location, the elongated body having an internal lumen, a proximal opening, and a distal opening, wherein the distal opening is formed by a distal edge of the catheter, and wherein the distal edge forms an angle that is non-perpendicular relative to a longitudinal axis of the elongated body;
wherein the elongated body has a proximal most section and a distal most section, the proximal most section being a stiffest portion of the elongated body, and wherein the elongated body has an overall length such that the distal most section can be positioned in the artery in the brain while the proximal most section is positioned in the common carotid artery during use;
wherein the distal most section of the catheter has an inner diameter of 0.035 to 0.062 inch;
wherein the catheter can navigate around a 180° bend with a radius of 0.100″ without kinking; and
wherein the catheter does not collapse when connected to a vacuum up to 25 inHg while navigating around a 180° bend with a radius of 0.100″.
