IUI Catheter

The gold standard of insemination, Select IUI catheters have dual openings that mirror the normal orientation of the fallopian tubes. TheCurve Intrauterine Insemination Catheter with Luer Lock hub has a rounded, beveled tip which helps to ensure smooth insertion, while the slight curve is designed to facilitate entry.

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.

TheCurve® is a single-use, sterile, disposable, flexible catheter designed for use in intrauterine insemination. The opening is at the tip of the catheter which has been rounded and beveled for the comfort of the patient. The distal part of the catheter has been curved to ease its insertion and for better patient comfort.

The Select IUI® 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 sheath 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 uterine cavity.

TheCurve® has an overall length of 19.9 cm including a 2.7 cm long polyethylene Luer-lock hub which is permanently affixed to its proximal end. The effective portion of the catheter (intended for insertion) comprises a 17.2 cm long clear polyethylene tube with a 1.6 mm O.D. (outer diameter) and a 1.1 mm I.D. (inner diameter). When filled, TheCurve contains 0.2 ml of fluid. The proximal 12.7 cm length of the catheter is tightly surrounded by a clear polypropylene sheath with a 2.6 mm O.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 1.6 mm over the 1 mm spindle-shaped portion. 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 1.6 mm O.D., 4.5 cm long distal portion and (ii) a more rigid 2.6 mm O.D., 12.7 cm long proximal portion. Graduation markings are placed at 5, 6, 7, 8, 9, and 10 cm distance from the extreme distal tip. The distal portion is curved to ease its passage into the cervical os and insertion through the cervical canal up to the uterine fundus.
