Abstract

Methods and devices using magnetic force to form an anastomosis between hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although such attachment means may be used in practicing some aspects of the invention. Magnetic anastomotic components may be attached to the exterior of a vessel, e.g., by adhesive, without extending into the vessel lumen. Various magnetic component configurations are provided and may have different characteristics, for example, the ability to match the vessel curvature or to frictionally engage the vessel.

Claims

1. An anastomosis device comprising:

a component configured to be secured to a vessel and having an opening adapted to be placed in fluid communication with a lumen of the vessel;

wherein the component comprises a material having the ability to produce or be attracted by a magnetic field; and

wherein the component is configured to be secured to the vessel substantially without any fixation structure being present in the vessel lumen.

2. The device of claim 1, wherein the component is configured to be secured to the vessel without any fixation structure being present in the vessel lumen.

3. The device of claim 1, wherein the component has a surface configured to be secured to the vessel wall by adhesive.

4. An anastomosis device comprising:

a component having a portion configured to be adhered to a wall of a vessel by biocompatible adhesive to define a blood flow path into the vessel; and

wherein the component is configured to be secured to the vessel wall by an additional, nonadhesive-based attachment mechanism.

5. The device of claim 4, wherein the portion of the component and the attachment mechanism are configured to secure the component to the vessel without any fixation structure being present in the vessel lumen.

6. The device of claim 4, wherein the component comprises a material having the ability to produce or be attracted by a magnetic field.

7. An anastomosis device comprising:

a component configured to be secured to a vessel and having an opening adapted to be placed in fluid communication with a lumen of the vessel;

wherein the component comprises a material having the ability to produce or be attracted by a magnetic field; and

wherein the component has a portion that is at least partially curved.

8. The device of claim 7, wherein the component is configured to be secured to the vessel wall by an adhesive.

9. A method for forming an anastomosis comprising:

(a) providing a first vessel with a first anastomotic component;

(b) providing a second vessel with a second anastomotic component; and

(c) coupling the first and second anastomotic components to place their lumens in fluid communication;

(d) wherein at least one of steps (a) and (b) is performed at least in part by securing the anastomotic component to the vessel using adhesive.

10. The method of claim 9, wherein step (c) is performed at least in part by using magnetic force to couple the anastomotic components.
