Abstract
A method for producing a detachable surgical needle-suture combination of the type incorporating a fluid swellable suture material is capable of producing needle-suture attachments which conform to the prescribed minimum pull-out forces for detachable needle-suture combinations as set forth in the U.S. Pharmacopeia. Generally, the method includes the steps of providing a surgical needle and a fluid swellable suture, immersing an end portion of the suture into a liquid solution whereby the suture end portion swells and assumes an expanded condition, positioning the suture end portion in its expanded condition into an aperture formed in the blunt end of the needle and swaging the blunt end of the needle to cause deformation of at least a portion of the blunt end and engagement with the suture end portion to effect needle-suture attachment.
