Wallace® Classic

Embryo Transfer Catheters

Our Classic range offers a soft-profiled tip associated with some of the highest pregnancy rates across the world1-5.

Key Features

  • Soft material and smooth tip minimizes trauma and maximizes success rates1-5
  • Formable outer sheath to suit different patient anatomies
  • Centimeter markings to show outer sheath depth and inner lumen protrusion for confidence of placement within the uterus
  • 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 rates6
  • The Classic range is fully compatible with the Sure View range
