Described herein are methods and devices that may be useful, for instance, in thrombectomy and embolectomy procedures, stent delivery procedures, and procedures for bridging the neck of an aneurysm. The bifurcated guidewire device described herein comprises a proximal end, a distal end, a length therebetween, and at least one bifurcation branching the guidewire into at least two arms. The arms are controllable, which may be accomplished, e.g., by providing arms constructed of a shape memory material, or by providing mechanical methods to control the arms. The guidewire may have any number of bifurcations branching the guidewire into any number of arms as practicable. The arms may or may not have radio-opaque markers thereon or be constructed of a radio-opaque material. The arms may have webbing or a semi-permeable sac disposed between them to help capture natural or foreign matter therein. The guidewire may be used with or without a catheter.
