Abstract: Medical devices and methods for making and using a medical device are disclosed. An example medical device may include a guidewire for accessing and treating a region of the neural vasculature. The guidewire may include an elongate shaft having a distal end region. The elongate shaft may include an inner tubular member and an outer tubular member. The inner tubular member may have a plurality of openings formed therein. The outer tubular member may have a plurality of slots formed therein. An occlusive balloon may be coupled to the distal end region of the elongate shaft and disposed about at least some of the plurality of openings. The inner tubular member may define a lumen in fluid communication with the occlusive balloon through the plurality of openings. The tip member may be coupled to the distal end region of the elongate shaft.
