SCu300A IUB

The **SCu300A IUB** is a **copper-based intrauterine device (IUD)** marketed under the name IUB (Intrauterine Ball). Unlike traditional T-shaped IUDs, the SCu300A IUB takes a three-dimensional spherical shape when deployed in the uterus. The device is constructed from a shape memory alloy wire, which is threaded with 17 pure copper spheres (providing a total copper surface area of 300 mm²), and the wire is coated with a thin polymer. The IUB is designed to improve user experience by minimizing risks of uterine perforation, malposition, and expulsion, while also possibly reducing discomfort, bleeding, and pain compared to standard IUDs. The main mechanism of action is the spermicidal and ovicidal effect of copper, which induces a hostile environment for sperm and ova, preventing fertilization. The IUB SCu300A is intended for long-term contraception, typically up to 5 years, and is inserted and removed similarly to other IUDs[1][3][5]. Developer and manufacturer is Ocon Medical. Primarily indicated for contraception in adult women.
