Artificial fertilization catheter

A catheter for artificial insemination, which comprises

• (a) a flexible hose-like catheter section defining a longitudinally extending internal passage and having a first terminal portion and a second, distal terminal portion opposite the first terminal portion, the distal terminal catheter section portion having
• (1) a rounded-off closed extremity and
• (2) two peripherally staggered radial outflow openings of different-sized outflow cross sections, one of the outflow openings being larger for outflow of semen and the second outflow opening being smaller for outflow of air,
• (3) the hose-like catheter section having a length enabling the hose-like catheter section to be inserted into a uterine cavity,
• (b) an impermeable flexible hose-like extension defining a longitudinally extending internal passage in alignment with the internal passage in the hose-like catheter section and having a terminal portion adjoining the first terminal portion of the catheter section,
• (1) the hose-like extension having a length corresponding substantially to the length of a vagina, and
• (c) a concial attachment at the first terminal portion of the hose-like catheter section and tapering inwardly towards the distal terminal portion thereof or attaching the hose-like extension to the hose-like catheter section, the conical attachment
• (1) having an internal passage in communication with the internal passages in the hose-like catheter section and extension, and
• (2) fitting into a cervical opening leading from the vagina into the uterine cavity.
