1. A catheter device, comprising:
an elongate body having a distal end and a proximal end;
a passageway extending along a part of the elongate body, the passageway including an opening positioned adjacent the distal end and along an outer wall of the elongate body; and
an injector slidably engaged with the passageway and configured to extend through the opening and penetrate tissue of a carotid artery;
an ejectable holdfast including a plurality of flexible extensions, the plurality of flexible extensions expanding and extending from the distal end of the elongate body when ejected from the distal end of the elongate body, each flexible extension of the plurality of flexible extensions comprising a single length of flexible material that extends between a distal extension end and a proximal extension end, the proximal extension end being coupled to the elongate body, the plurality of flexible extensions radially expand and allow each distal extension end to contact inner walls of a carotid artery when the plurality of flexible extensions are ejected and extending from the distal end of the elongate body; and
wherein the plurality of flexible extensions all have distal ends that are disposed distally of the distal end of the elongate body when the plurality of flexible extensions are ejected from the distal end of the elongate body.
