Case Discussion
These devices are made of a soft flexible plastic that slowly releases synthetic progesterone for hormonal contraception. It is inserted under local anesthetic by a preloaded disposable applicator and is easily removed under local anesthetic but may require US guidance for removal. The plastic contains a small amount of barium sulfate to allow radiographic localization. Contraceptive effect can last for 3 years. The most common location for insertion in the medial arm.
