  • Tipped multifilament surgical suture
    Patent number: 5569302
    Abstract: A multifilament surgical suture has an end portion tipped with cyanoacrylate resin. The suture can also include filling agents and lubricants which are incorporated into the suture prior to the suture being tipped. A typical filling agent is glycerol. A typical lubricant includes a copolymer of glycolide and lactide. Tipping is accomplished by passing a portion of the suture through a mist of monomeric cyanoacrylate resin and allowing the resin to harden by curing. The tipped portion may then be cut to create a tipped end for insertion into a surgical needle.
    Type: Grant

  • Method and apparatus for tipping sutures
    Patent number: 5437726
    Abstract: An apparatus for tipping surgical sutures includes a drum around which the suture is wound. The drum is placed on a carriage which moves the drum into a chamber wherein selected portions of the suture are passed through a mist of cyanoacrylate tipping agent generated by ultrasonic atomization. The tipping agent quickly cures and the tipped portion of the suture may be cut to create a tipped end for insertion into a surgical needle to form a needle-suture device.

    Inventors: George R. Proto, Francis D. Colligan, Harold Bellmore, Jr.
  • Suture-needle combination with cyanoacrylate tipped sutures
    Patent number: 5425746
    Abstract: A method and apparatus for tipping surgical sutures which includes winding the suture around a drum while continuously monitoring the suture diameter in x and y directions and adjusting the tension on the suture to control the suture diameter as it is being wound. The drum is then placed in an apparatus which passes selected portions of the suture through a mist of cyanoacrylate tipping agent generated by ultrasonic atomization. The tipping agent quickly cures and the tipped portion of the suture may be cut to create a tipped end for insertion into a surgical needle to form a needle suture device.
