发明名称 Artificial fertilization catheter
摘要 The invention specifies a catheter for artificial fertilization, which is provided with a flexible hose-like catheter section insertible into the uterine cavity of a womb via the cervical cavity. In a terminal portion allocated to a cervical passage, there is provided a conical attachment enlarging rearwardly. A passage in the other terminal portion facing away from the attachment, is closed off at the forward and end, is rounded off or made in spherical cap form. The passage is provided rearwards of the rounded-off terminal portion with two peripherally staggered and radially extending outflow openings. The hose-like catheter section has a flexible hose-like rearward extension extending from the conical attachment. The length of the hose-like extension corresponds substantially to the length of a vagina.
