Patent number: 5569302Abstract: 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: GrantFiled: March 3, 1995Date of Patent: October 29, 1996Assignee: United States Surgical CorporationInventors: George R.

Patent number: 5425746Abstract: 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.Type: GrantFiled: September 14, 1993Date of Patent: June 20, 1995Assignee: United States Surgical CorporationInventors: George R. Proto, Francis D. Colligan, Harold Bellmore, Jr.

Patent number: 5374278Abstract: A heat tipping method and apparatus for surgical sutures to facilitate inserting the sutures into the barrel ends of surgical needles. The method comprises tensioning the suture, heating a portion of the suture to be heat tipped by blowing a current of hot air across the portion of the suture, and releasing the tension and cutting the portion of the suture to create heat tipped ends. The apparatus comprises a cylindrical drum around which the suture is wound, a concave channel in the drum for delimiting a portion of the suture to be heated, and hot air blowers for heating the delimited portions of the suture to a heat tipping temperature. In another embodiment, the suture is looped and knotted. The loop and/or knot is then heated under such conditions so as to reversibly stiffen the loop and/or knot. Such stiffening facilitates placement and securement of the suture loop during surgical procedures.Type: GrantFiled: October 19, 1992Date of Patent: December 20, 1994Assignee: United States Surgical CorporationInventors: Michael P. Chesterfield, Stanley J. Malinowski, George R. Proto, Jonathan Wilson

Patent number: 5259846Abstract: A loop threaded needle-suture device is disclosed wherein a surgical needle is provided with a pointed end and a drilled aperture extending axially of the butt end, and a length of flexible suture material is doubled upon itself to form a loop, both free ends of which are attached to the needle in the butt end aperture. The blunt end of the needle is deformed to form the aperture into an elliptical cross-section and the length of the loop is substantially greater than the length of the needle to facilitate insertion of the needle and suture material into tissue to be sutured, and looping the needle through the suture material prior to tieing the suture material. Thus, the loop functions as a double suture. A method of forming the unique loop threaded needle-suture is disclosed.Type: GrantFiled: January 7, 1991Date of Patent: November 9, 1993Assignee: United States Surgical CorporationInventors: Richard N.

Patent number: 5168619Abstract: An apparatus is disclosed for attaching a surgical needle having a generally cylindrical end portin defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the needle. The apparatus includes a pair of dies, each having a generally arcuate surface portion having irregularities including concave portions such that when the cylindrical end portion of the suture is positioned within the aperture of the needle and the dies are positioned about the generally cylindrical end portion of the needle with the surface portions facing the outer surface thereof, the application of inward force to the dies causes the dies to impact the needle and produces inward crimping of the needle so as to attach the needle to the suture.Type: GrantFiled: June 10, 1991Date of Patent: December 8, 1992Assignee: United States Surgical CorporationInventors: George R.
