title: The IUB, a newly invented IUD: a brief report.
abstract: OBJECTIVE
  To evaluate the initial safety and effectiveness of the intrauterine ball (IUB), a copper intrauterine device that, upon insertion in the uterus, takes a three-dimensional spherical form.
  
  
  METHODS
  Fifteen women were followed for 1 year, with follow-up visits at 1, 3, 6, 9 and 12 months.
  
  
  RESULTS
  The physician reported that all devices were very easy to insert. One subject discontinued before the 6-month visit (at 119 days after insertion) for a reason not related to the device. There were no perforations, expulsions, malpositions or complications, or pregnancies.
  
  
  CONCLUSIONS
  No safety or efficacy concerns were raised.
  
  
  CONCLUSIONS
  Due to its form and deployment process the IUB is expected to ease insertion and reduce perforation, malposition and expulsion rates and may also reduce dysmenorrhea and menorrhagia.
