The Select IUI ® is a single-use, sterile, disposable, flexible catheter designed for use in intrauterine
artificial insemination. Two lateral openings opposite one another, of a 1.2 mm diameter each,
are located at 1.5 mm distance from the extreme distal, rounded, smooth, closed tip of the catheter.
The device has an overall length of 20 cm including a 3 cm long polyethylene Luer-lock hub
which is molded onto its proximal end. The effective portion of the catheter (intended for
insertion) comprises a 17 cm long clear polyethylene tube with a 2.1 mm O.D. (outer
diameter) and a 1.6 mm I.D. (inner diameter). The proximal 12.5 cm length of the catheter is
tightly surrounded by an outer, clear polypropylene heath with a 2.6 mm O.D. and a 2.15 mm I.D. for
all but the distal 1 mm length, which joins the inner tube to the outer sheath. At this 1 mm joining
length, the O.D. tapers inward from 2.6 mm to 2.1 mm. This leaves 4.5 cm of the inner catheter
tube exposed at the distal end. The proximal inner tube and the outer sheath
circumferences are molded directly onto the distal end of the Luer-lock hub so that only the lumen of
the inner tube can provide a channel for flow. This design results in a single-channel catheter
with two segments each having different degrees of flexibility: (i) a highly flexible 2.1 mm O.D.,
4.5 cm long distal portion and (ii) a more rigid 2.6 mm O.D., 12.5 cm long proximal portion.
Graduation markings are at 5, 6, 7, 8, 9, and 10 cm distance from the extreme distal tip.
The two wings of the Luer-lock hub are positioned in line with the two catheter distal openings to
enable orientation of these openings with tubal ostia while the catheter is in place within the
