1. A method of performing a medical procedure at a treatment site in a cerebral vessel of a patient, the method comprising:
delivering a neurovascular catheter through a working lumen of a sheath to a treatment location distal to a petrous portion of an internal carotid artery, the neurovascular catheter comprising:
an elongate control element configured to advance the neurovascular catheter comprising a flat ribbon; and
a distal luminal portion extending along a longitudinal axis having a proximal end region coupled to the control element, wherein the distal luminal portion has a side wall defining a single, inner lumen, the side wall comprising:
a tubular inner liner;
a reinforcement structure wound around and bonded to the tubular inner liner; and
an outer jacket surrounding the reinforcement structure,
wherein a distal end of the elongate control element is coupled to the proximal end region of the distal luminal portion sandwiched between layers of the side wall, and
wherein the proximal end region of the distal luminal portion includes a step-up in outer diameter to form a seal with the working lumen of the sheath; and
applying suction through the working lumen of the sheath and the single, inner lumen of the neurovascular catheter to the treatment location from a single source of suction.
