The instrument has impressive adaptation within the uterine cavity, regardless of size and dynamics. Due to its shape, it offers great flexibility. Good molecular memory allows for it to return to its original shape. Insertion into narrow neck holes and easy reading can be achieved thanks to the thin cannula. For optimal efficiency, the unit features an area of approximately 380 mm(2) of a copper active contraceptive. The removal process is easy as well. The design is ideal for use in nuliparous or parous women who have had problems with other types of IUDs.
