Abstract

The present disclosure provides modular magnetic anastomosis devices that can be implemented in digestive surgery or in any circumstance of anastomosis between adjacent organs or two hollow viscera. The device is minimally invasive and easily and quickly delivered using laparoscopic or endoscopic procedures.

Claims (22)

1. A method for creating tissue anastomosis comprising:

(i) delivering a first modular magnet assembly to a first location within a body, wherein the first modular magnet assembly is configured for placement on a first body wall, and wherein the magnets of the first modular magnet assembly are positioned so that an even number of dipoles of the magnets of the first modular magnet assembly have an alternate north-south, south-north orientation;

(ii) delivering a second modular magnet assembly to a second location within the body, wherein the second modular magnet assembly is configured for placement on a second body wall;

(iii) placing the first modular magnet assembly and the second modular magnet assembly on the first body wall and the second body wall respectively.

2. The method of claim 1 , wherein the delivering of the first modular magnet assembly or the second modular magnet assembly comprises using a laparoscopic trocar.

3. The method of claim 1 , wherein the delivering of the first modular magnet assembly or the second modular magnet assembly comprises implanting the first modular magnet assembly or the second modular magnet assembly using endoscopy.

4. The method of claim 1 , wherein the placing is characterized by placing the first modular magnet assembly within a distance of the second modular magnet assembly such that they are magnetically attracted to one another through a defined tissue area.

5. The method of claim 4 , wherein the placing of the first modular magnet assembly and the second modular magnet assembly comprises configuring the first modular magnet assembly and the second modular magnet assembly to couple together, thereby forming a magnetic coupling.

6. The method of claim 5 , wherein the placing of the first modular magnet assembly and the second modular magnet assembly comprises configuring the magnetic coupling to compress the first body wall and the second body wall between the first modular magnet assembly and the second modular magnet assembly respectively.

7. The method of claim 6 , wherein the placing of the first modular magnet assembly and the second modular magnet assembly comprises compressing of the first body wall and the second body wall to form an anastomosis between the first body wall and the second body wall.

8. The method of claim 1 , wherein the first modular magnet assembly or the second modular magnet assembly comprise a chain of magnets arranged and maintained on a structure made of resilient material or on a structure with shape memory.

9. The method of claim 8 , wherein the structure made of resilient material or the structure with shape memory comprises a band of material surrounding the circumference of the chain of magnets.

10. The method of claim 8 , wherein the structure made of resilient material or the structure with shape memory comprises a biodegradable material or a biocompatible material.

11. The method of claim 1 , wherein the first modular magnet assembly or the second modular magnet assembly comprises a wire guide.

12. The method of claim 11 , wherein the placing comprises positioning the first modular magnet assembly or the second modular magnet assembly with the wire guide.

13. The method of claim 11 , wherein the placing comprises switching the first modular magnet assembly or the second modular magnet assembly from a delivery configuration to a deployment configuration.

14. The method of claim 13 , wherein the switching of the first modular magnet assembly or the second modular magnet assembly from a delivery configuration to a deployment configuration comprises a manipulation of the wire guide.

15. The method of claim 14 , wherein the manipulation of the wire guide comprises pulling on the wire guide.

16. The method of claim 1 , comprising an excising step.

17. The method of claim 16 , wherein the excising step comprises introducing a cutting instrument and manipulating the cutting instrument.

18. The method of claim 1 , further comprising removing the first modular magnet assembly or the second modular magnet assembly.

19. The method of claim 18 , wherein the removing comprises performing laparoscopic removal, performing endoscopic removal, or allowing natural passage through the body.
