Abstract
Described here are devices, systems, and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter and a second catheter, which may comprise one or more fistula-forming elements. The first and second catheters may comprise one or more magnets, which may be used to assist in bringing the first and catheters in closer proximity to facilitate fistula formation. In some variations, the magnet may have a plurality of magnetic domains each characterized by a magnetic flux vector, with the magnetic flux vectors of the magnet passing through a common magnetic origin.
