Endoscopic magnetic anastomosis system, and methods and devices for forming an anastomosis

An endoscopic anastomosis system, the endoscopic anastomosis system comprising:

• a first main body assembly, the first main body assembly being an elongated body having a first end and a second end, at least a portion of the second end of the first main body assembly controllable to bend in a plurality of directions;
• a head assembly, the head assembly having a first end and a second end, the head assembly including:
• a head assembly body, the head assembly body including:
• a first region, the first region having a first end, a second end, and a midsection between the first and second ends of the first region, the first end of the first region secured to the second end of the first main body assembly, the second end of the first region including:
• a first section, the first section secured to a first end of a second region of the head assembly;
• and
• a second section, the second section having a second main body assembly opening;
• and
• the second region, the second region having the first end and a second end, the second end of the second region including:
• a first pressure port, the first pressure port configured to apply a negative pressure;
• and
• a first expandable member, the first expandable member secured to at least a portion of the midsection of the first region of the head assembly body, the first expandable member configured to expand radially away from the first region of the head assembly body;
• a second main body assembly, the second main body assembly being an elongated body having a first end and a second end, at least a portion of the second end of the second main body assembly provided in and moveable through the second main body assembly opening of the second section of the first region of the head assembly body, the second main body assembly including:
• a second expandable member, the second expandable member secured to a portion of the second end of the second main body assembly, the second expandable member configured to expand radially away from the second main body assembly;
• and
• a second pressure port, the second pressure port configured to apply a negative pressure;
• a magnetic implant assembly, the magnetic implant assembly including:
• a magnetic body, the magnetic body formed as a cylindrical body with a central axis, the magnetic body including:
• a front wall;
• a rear wall opposite to the front wall;
• and
• an exterior circumferential sidewall formed around the magnetic body, the exterior circumferential sidewall defining a thickness of the magnetic body, the exterior circumferential sidewall formed at a first radius from the central axis;
• and
• a securing assembly, the securing assembly secured to the second end of the second main body assembly, the securing assembly actuatable between a locked configuration and an unlocked configuration, the locked configuration being a configuration in which the magnetic implant assembly is secured to the securing assembly, the unlocked configuration being a configuration in which the magnetic implant assembly is not secured to the securing assembly.
