Abstract
Methods, systems, and devices for facilitation of intraluminal medical procedures within the neurovasculature including a catheter advancement element an inner diameter that is at least about 0.014″ up to about 0.024″ and an outer diameter having at least one snug point. A difference between the inner diameter of the distal, catheter portion and the outer diameter of the tubular portion at the snug point is no more than about 0.010″. A tip portion located distal to the at least one snug point of the tubular portion has a length and tapers along at least a portion of the length of the tip portion, wherein the tip portion has a distal point located a distance of at least 5 mm proximal from the distal-most end of the catheter advancement element, the distal point having a bending force that is no greater than about 0.05 Newtons.
