Devices. 2016;10(1): doi: / Figure Legend: Illustration of the Magnamosis procedure: (a) the first magnet is installed at the distal end using laparotomy and (b) the second magnet is installed at the proximal end using an endoscope. In this case, it is in the stomach. (c) The two magnets are bought close to each other. (d) The magnets are self-aligned and are attracted to each other. (e) Once the entire tissue between the two magnets is completely necrosed, it is dislodged and comes out of the rectum.

Devices. 2016;10(1): doi: / Figure Legend: Testing configuration. The inductor coil printed on a printed circuit board is placed on the first magnet. Polycarbonate sheets of thickness 0.6 mm are used to simulate the tissue. (a) The second magnet is not modified and is used as is and placed on the polycarbonate sheets. (b) The aluminum foil is used as the second conducting target. (c) The aluminum foil is used in conjunction with the second magnet. (d) Symmetric configuration. Two coils are mounted on each magnet. The two coils are connected in series.

Devices. 2016;10(1): doi: / Figure Legend: Experiment setup with pig intestine between the two magnets. The bottom magnet and the inductor coil are kept in a polycarbonate cover to avoid short circuiting of the inductor coil due to contact with the tissue. In a clinical setting, this will be avoided be including the inductor coil within the polycarbonate casing that holds the magnet.

One coil is mounted below the magnet, and the second magnet is on top of the magnet. Both the magnets are thus identical and is referred to as symmetric setup/also shown in the same graph the results with single coil to highlight the contrast.
