Key Features of  TT1816 and TT1816N

  • Trial transfer catheters allow for confident positioning of the outer sheath before introducing the embryo loaded inner. Clinicians have found this technique to have a positive impact on pregnancy rates 6
  • Same soft material and smooth tip as the Classic catheter to minimise trauma
  • Formable outer sheath to suit different patient anatomies
  • Centimetre marking to show outer sheath depth and inner lumen protrusion for confidence of placement
  • Fully compatible with the Wallace Classic Catheter ranges and stylets
  • Also compatible with SureView® range

Key Features of CE418 and CE423

  • Visible under ultrasound from hub to tip7
  • Trial transfer catheters allow for confident positioning of the outer sheath before introducing the embryo loaded inner. Clinicians have found this technique to have a positive impact on pregnancy rates 6
  • Same soft material and smooth tip as the Classic and Sureview catheter to minimise trauma
  • More accuracy and confidence when positioning catheter tip within uterus before embryo transfer
  • Formable outer sheath to suit different patient anatomies
  • Centimetre marking to show outer sheath depth and inner lumen protrusion for confidence of placement
  • Fully compatible with the Wallace Classic Catheter ranges and stylets
