FredAttorney, Agent or FirmInternational ClassesA61B 17/11 (20060101)A61B 17/03 (20060101) AbstractA preferred embodiment of the anastomosis device comprises a cylindrical, radially resilient spring upon which is attached a number of outwardly extending barbs. The radial spring action significantly simplifies the anastomosis procedure and in addition allows the mended portion of the blood vessel to pulsate in a fashion similar to that of the pulsatile action of an unmended vessel. The barbs attach the device to the blood vessel thus maintaining its position securely. The disclosed anastomosis device is recommended for rejoining small blood vessels where a simple, reliable alternative to micro-suturing techniques is desirable. In the anastomosis method of the present invention a cylindrical, radially resilient spring is compressed and placed about one end of a vessel. The second end of the vessel is then placed about the spring and the compression is released. | |
