Abstract
Magnetic anastomosis devices constructed from magnetic segments coupled together with members that help the devices spontaneously transform from a linear delivery configuration to a polygonal deployment configuration. When two devices are joined together over tissue(s), the compressive force causes the tissue(s) to necrose and form an anastomosis. By altering the arrangement of the magnetic poles of the magnetic segments in the devices, the magnetic interaction between paired devices can be altered. This property gives surgeons flexibility in choosing how much attractive force the devices will experience during a procedure.
