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 device has an over all 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, The Curve 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.
