    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
