Abstract
Methods and devices use magnetic force to form a magnetic port in a hollow body. Additional methods and devices form anastomoses between two or more hollow bodies. First and second anastomotic securing components create a fluid-tight connection between the lumens of the 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 mechanical attachment structure may be used in conjunction with the magnetic attachment. The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may be used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts, etc. The system may be sized and configured for forming an anastomosis in or between a specific hollow body, for example, a coronary artery, the aorta, a radial artery, etc.
