Ronen Kadushin (b. 1964) is an Israeli designer and design educator living in Berlin. In 2004 Kadushin developed the Open Design concept, where the designs of his products can be downloaded, copied, modified and produced, much as in Open Source software.

One interesting object Kadushin designed and produced is "Bearina IUD Concept".

The intrauterine device (IUD) is the world's most widely used method of reversible birth control for women. But as their production and common materials cost only a few cents, they are sold for a staggering 400$- 850$, unreachable for many women, especially young ones.


The Bearina IUD is a political product. It demonstrates the disruptive potential of 3D printed Open Designs to give free and global access to essential products, and circumvent industries (such as the Pharma industry) that aggressively defend their intellectual property to control the price and availability of their products.

Description of the Bearina IUD:

In copper- containing IUDs, metal ions dissolving from the device create a spermicidal action. To do precisely that, a 1€ cent coin (copper covered steel) easily snaps in the plastic 3D printed part. An additional piece of nylon string is tied to the bottom part to complete the assembly of the Bearina IUD.

The Bearina IUD is a conceptual product and absolutely should not be used as an IUD or for any internal use. But as an Open Design, it is designed in relation to dimensions, materials and shapes commonly found in IUDs. And it is available for experimenting with and improving, and could evolve into a functional IUD.

The Bearina IUD can be downloaded here on Kadushin's site. You can also order some 3D printed Bearinas from Kadushin's Shapeways store for 1.25€ each.

The problem is that the uterus is sterile - chucking a non-sterile printed IUD and a grubby coin in there isn't great, and you also need to make sure you use monofilament non-wicking and acid-resistant string, so the string doesn't track bacteria up from the vagina! Pretty difficult to put together safely without a proper production line, but a great demonstrator!

The biggest problem that is not solved with that product is how to insert it without knowledge and/or help from a specialist. There will be al lot of broken devices and serious injuries caused by the fragments. Hope your liability insurance is capable enough...
