MOUNTAIN VIEW, Calif., Feb. 24, 2011 (GLOBE NEWSWIRE) -- Conceptus Inc. (Nasdaq:CPTS), developer of the Essure® procedure, the most effective non-surgical permanent birth control method available, today announced receipt of the CE mark for use of Transvaginal Ultrasound ("TVU") to confirm proper placement of Essure micro-inserts three months following the Essure procedure. TVU is an alternative to the standard flat plate pelvic X-ray, and both will be included in the European Physicians' Instruction for Use. TVU takes place in the physician's clinic, while X-rays typically are taken at a radiology facility. Essure micro-inserts are radiopaque, which enables physicians to visualize the location of the micro-inserts using either TVU or the standard flat plate pelvic X-ray. TVU is a non-invasive technique that uses sound waves sent out by an ultrasound probe to create a live picture (a sonogram) showing the reproductive organs. TVU advantages for patients include the ability to return to the familiar setting of the physician's clinic and avoid ionizing radiation associated with X-rays. TVU advantages for physicians include more control over the entire Essure procedure and improved patient compliance with the confirmation process. M.P.H. Vleugels MD PhD FRCOG, department Obstetrics and Gynecology, Riverland Hospital Tiel, the Netherlands and S. Veersema MD FRCOG, department Obstetrics and Gynecology St. Antonius Hospital Nieuwegein, the Netherlands, led an investigator-sponsored study of TVU as an alternative confirmation test for the Essure procedure. Following a two-year, multi-center cohort study with more than 1,000 patients, Drs. Vleugels and Veersema verified that the cumulative failure rate for patients who had the Essure procedure and TVU test was less than laparoscopic sterilization methods. Their research supported Conceptus' submission to receive the CE mark for TVU. "Gynecologists who perform Essure procedures can now confirm placement without having to rely upon a radiologist for an X-ray. In addition, using TVU instead of an X-ray enhances patient safety by eliminating exposure to ionizing radiation and reduces cost to the health care system," said Dr. Vleugels. "This streamlined process is more convenient, less expensive and may enhance patient compliance."
