Modular magnetic devices for use in creating tissue anastomosis

A modular magnet assembly comprising:

• a) a first set of modular magnets;
• and
• b) a second set of modular magnets,
• wherein the first set of modular magnets and the second set of modular magnets are configured for placement on a first body wall and a second body wall respectively, within such a distance that the first set of modular magnets and the second set of modular magnets are magnetically attracted to one another through a defined tissue area, and are further configured to magnetically couple such that a magnetic coupling of the first set of modular magnets with the second set of modular magnets compresses the first body wall and the second body wall between the magnetically coupled first set of modular magnets and second set of modular magnets to form an anastomosis between the first body wall and the second body wall;
• wherein the first set of magnets and the second set of magnets each independently form a chain of magnets arranged and maintained on a structure made of resilient material or with shape memory;
• and
• wherein the structure made of resilient material or with shape memory comprises a band of material surrounding the circumference of the chain of magnets;
• and wherein the modular magnetic assembly is attached to a wire guide for delivery;
• and wherein the wire guide is directly attached to each magnet of the chain of magnets or to the band of material.
