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.

Aspiration catheter systems and methods of use

An anchoring delivery system for use in an intracranial artery is provided including a tethering device having an elongated tether and an anchor coupled to a distal end of the tether. The anchor is deployable from a low profile configuration to a higher profile configuration to fix the distal end of the tether at an anchoring site in an anchoring vessel. The tethering device is configured to be used with a guide-sheath having a lumen configured to receive the tether. Related devices, systems, and methods are also described.

Anchoring delivery system and methods

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.
