Abstract:
1. A method of disrupting flow through a fistula, the method comprising: advancing a microcatheter through a guide catheter, the guide catheter having a distal end at a first point in vasculature, the microcatheter having a distal end; advancing a steerable microwire through the guide catheter, the steerable microwire extending distal to the distal end of the microcatheter; after advancing the steerable microwire through the guide catheter, further advancing and steering the steerable microwire to a second point in the vasculature, the fistula being proximate to the second point in the vasculature; after further advancing and steering the steerable microwire, advancing the microcatheter over the steerable microwire to the second point in the vasculature; after further advancing the microcatheter over the steerable microwire to the second point in the vasculature, removing the steerable microwire; advancing a flow disruptor through the microcatheter to the second point in the vasculature, the flow disruptor comprising, in an expanded state: expanding the first bulb and the second bulb on a first side of the fistula; extending the second neck through the fistula; and expanding the third bulb and the fourth bulb on a second side of the fistula.
