  • Surgical needle swage tool
    Patent number: 8214996
    Abstract: In a method of attaching a suture to a needle barrel, a first compression stroke compresses the radially-defined top of the barrel against a suture in the bore of the barrel while restraining the bottom and sides of the barrel against deformation. A second compression stroke compresses the bottom of the barrel against the suture while restraining the sides against deformation. In another method, the top and bottom are compressed concurrently while the sides are restrained against deformation. An apparatus for attaching a suture to a needle barrel includes two die sets, each including a die with a groove therein. In one die set, the groove protects the bottom and sides of the barrel from deformation while the top is compressed. In the other die set, the groove protects the sides of the barrel from deformation while the bottom is compressed.
