  • Publication number: 20160346827
    Abstract: A method is used for fabricating a surgical needle for use in with a circular needle applier having a needle driver. A wire body is straightened and cut to an initial length, the wire body having a first end and a second end. A point is ground on the first end of the wire body. The wire body is plastically deformed to form two recessed features adapted to be engaged by a needle driver. The wire body is cut to a final length with a trailing end. A hole is drilled in the trailing end to create a barrel. The wire body is bent along a circular arc while keeping straight a trailing portion with the barrel. A length of suture is attached in the barrel. The trailing portion is bent along the circular arc.
