US BIODESIGN PTFE Felt Sheets are used by suture OEMs to produce various shapes and sizes of non-absorbable suture pledgets.  Pledgets are used by surgeons as suture buttresses to protect delicate tissue from possibility of the suture cutting into/through the tissue.

  • Cardiovascular repair
  • Orthopedic repair
  • Vascular closure
  • Septal repair
  • Myocardial closure
