Das hier hab ich eben zufällig entdeckt. Möglich, dass es hier schon besprochen wurde. Wohl eine neue Generation der IUDs, die noch getestet wird. Was sagt ihr?

An important feature includes its downwards curving opposite to the uterine fundus as it emerges out of the tube, minimizing the risk of perforation. The three dimensional shape's elasticity allows for better amenability to the uterus, nullifying the possibility of malposition and its final outer diameter reducing the probability of expulsion. Lacking rigid or protruding segments and being significantly smaller than other IUDs, the IUB™ is expected to reduce distortion and tissue irritation, possibly resulting in less bleeding, discomfort and pain, leading to lower discontinuation rates. A thread is attached to the IUB™ to allow easy removal.
The trialed IUB™ will be copper-based (Cu surface area of 300mm2). […]"
