Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal portion coupled to a proximal end region of the flexible elongate body and extending proximally to a proximal-most end of the catheter advancement element. A hardness of the flexible elongate body transitions proximally towards increasingly harder materials up to the proximal portion forming a first plurality of material transitions. At least a portion of the flexible elongate body is formed of a plurality of layers including a reinforcement layer. An outer diameter of the flexible elongate body is sized to be positioned coaxially within a lumen of a catheter such that a distal tip portion of the flexible elongate body extends distally beyond a distal end of the catheter to aid in delivery of the catheter to an intracranial vessel.

Single Operator Intracranial Medical Device Delivery Systems And Methods Of Use
A rapid exchange microcatheter for accessing the intracranial neurovasculature. A side opening through the sidewall is located a first distance proximal to the distal-most tip. A proximal opening located proximal to the side opening is a second distance from the distal-most tip. A distal, reinforced catheter portion extends between a distal end region to a point near the side opening. A proximal, reinforced catheter portion extends a distance from a point near the side opening towards the proximal end of the catheter body. The side opening is positioned within a gap between a proximal end of the distal reinforced catheter portion and a distal end of the proximal reinforced catheter portion. A payload of a cerebral treatment device is housed within the lumen proximal to the side opening. Related devices, systems, and methods are disclosed.
