For easy transfer of washed sperm into the uterine cavity, in Artificial Insemination procedures. Single lumen, radiopaque transparent catheter with different stiffness: - Rigid proximal portion (2) for easy insertion through the cervix; - Flexible, soft, distal tip (3), for atraumatic and gentle seminal transfer. Centimeter-marking (50-60-70 mm) determines the penetration depth. A female luer lock connector (1) serves as finger grip and allows a safe syringe connection for sperm injection. The two orientation wings aligned with the double side-eyes placed on the distal tip, enhance accurate placement of the catheter. Rounded tip ensures a smooth insertion through the cervix; double side-eyes allow an excellent distribution of the seminal fluid. AINSEBLUE is not intended for in vitro fertilization and Intra Falloppian tubes procedures.
