Abstract: Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

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.

Abstract: Processes for forming magnetic anastomotic components subject suitable stock material to a series of steps to produce a biocompatible device for implantation in a patient's body. The processes treat the exterior of the material to form a smooth outer surface free of irregularities and discontinuities. The anastomotic component may undergo additional processing, for example, applying one or more coatings, changing the surface configuration of the component or creating one or more areas of concentrated magnetic flux. According to another aspect of the invention, the anastomotic component is magnetized after it has been packaged. Finally, the exterior of the component may be rendered smooth after initial forming by an acid etching process that is carried out pursuant to principles of the invention.

Abstract: Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.

Abstract: Anastomotic methods and devices for placing a target vessel in fluid communication with a target vessel. A conduit includes an attachment portion adapted to be secured to a target vessel in fluid communication with the lumen of the vessel. The target vessel wall is sandwiched between first and second components of the attachment portion to provide both a secure and sealed connection. One component is placed in the vessel lumen against the interior surface of the wall and has an outlet that directs blood into the target vessel. This component is elongated, e.g., elliptical or rectangular, such that a minimum amount of material is present at the outlet. This results in the outlet having a diameter that substantially maintains much of the cross-sectional area of the native target vessel.
