  • Method for making fast absorbing sutures by hydrolysis
    Patent number: 6945985
    Abstract: A method for making a surgical article is provided which comprises exposing a bioabsorbable material, e.g., a copolymer derived from a major amount of glycolide and a minor amount of lactide, to a humid environment either prior to coating the material or prior to or following sterilization of the material for a time period and at a temperature sufficient to predegrade the resulting surgical article.
    Type: Grant
    Filed: December 4, 2002
    Date of Patent: September 20, 2005
    Assignee: Tyco Healthcare Group LP
    Inventors: John Kennedy, Mark S. Roby, Matthew E. Hain

  • Spiroid braided suture
    Patent number: 5662682
    Abstract: A suture is provided with a solid spiroid braid construction. The suture exhibits greater flexibility, better hand and less chatter and drag than tubular braided sutures of known construction.
    Type: Grant
    Filed: January 15, 1993
    Date of Patent: September 2, 1997
    Assignee: United States Surgical Corporation
    Inventors: Michael P. Chesterfield, Ilya Koyfman, Matthew E. Hain
  • Dynamic treatment of suture strand
    Patent number: 5294389
    Abstract: A suture strand is subjected to dynamic treatment by passing the suture with multiple turns around at least two godets located within a heating zone provided by an oven. The suture strand can be bioabsorbable or non-bioabsorbable, and either monofilament or multifilament. A combination of large and small diameter godets in the oven can achieve dynamic relaxation or stretching.
    Type: Grant
    Filed: April 26, 1993
    Date of Patent: March 15, 1994
    Assignee: United States Surgical Corporation

    Inventors: Matthew E. Hain, Cheng-Kung Liu
  • Spiroid braided suture
    Patent number: 5181923
    Abstract: A suture is provided with a substantially solid spiroid braid construction. The suture exhibits greater flexibility, better hand and less chatter and drag than tubular braided sutures of known construction.
    Type: Grant
    Filed: August 17, 1990
    Date of Patent: January 26, 1993
    Assignee: United States Surgical Corporation
    Inventors: Michael P. Chesterfield, Ilya Koyfman, Matthew E. Hain
  • Combined surgical needle-spiroid braided suture device
    Patent number: 5133738
    Abstract: A surgical needle is attached to a spiroid braided suture to provide a combined surgical needle-spiroid braided suture device. A shrinkable tubing is employed to secure the needle to the suture. The tubing shrinks in response to the application of energy, e.g., heat. Attachment parameters may be controlled to provide standard needle attachment or removable needle attachment.
    Type: Grant
