A catheter assembly for performing embryo implants in a female's uterus including an inner component having an echogenic soft distal tip for supporting the embryo to be implanted in the womb. A guide cannula receives the inner component which in combination with the rigid proximal portion facilitates insertion of the distal tip and embryo into the womb through the cervix. The guide cannula is a hollow tubular member attached to the hub, and a distal end which protects the embryo on the inner component during insertion. Markings indicate the position of the soft distal tip of the inner component with respect to the guide cannula as well as the overall length of the catheter assembly. During the implantation process, ultrasound imaging equipment is used to monitor the position of the echogenic distal tip.
