Surgical Suture Testing

Sutures are used in a variety of different surgical procedures to close wounds and aid in tissue healing. Sutures can be designed to biodegrade into the body or be removed after a certain period of time. Testing the tensile strength of sutures is a critical measure of performance to determine how likely the stitch is to break. Precise, consistent and reliable measures of strength are essential for product development and quality control.

The U.S. Pharmacopeia (USP) defines the test requirements for surgical sutures made from synthetic or natural materials which may be absorbable or non-absorbable. DDL performs all of the mechanical tests required to demonstrate compliance with the suture Monographs.

The mechanical tests defined in the USP are:

  • Suture Length
  • <861> Suture Diameter
  • <871> Needle Attachment
  • <881> Tensile Strength
