1. A method of occluding an artery, comprising:
advancing a catheter through the artery to a site at which an occlusion is desired, the catheter having a side port just proximal of an inflatable balloon disposed near a distal end of the catheter;
inflating the inflatable balloon;
advancing a puncture guidewire through a lumen of the catheter, out of the side port and into a subintimal space of the artery, where the inflated inflatable balloon guides the puncture guidewire towards a wall of the artery;
advancing an occlusion implant over the puncture guidewire into the subintimal space; and
withdrawing the puncture guidewire, leaving the occlusion implant positioned within the subintimal space.
