Conceptus Submits PMA Supplement to Support Essure Four- and Five-Year Effectiveness.

SAN CARLOS, Calif. -- Conceptus, Inc. (Nasdaq:CPTS), developer of the non-incisional permanent birth control procedure Essure(R), today announced that it has submitted a Pre-Market Approval (PMA) supplement to the U.S. Food and Drug Administration (FDA) in order to extend effectiveness data on the Essure product labeling. E[acute accent]The supplemental filing supports an extension of the effectiveness of Essure to four and five years of follow-up and is expected to be unchanged from the 99.8% effectiveness rate for one, two and three years of follow-up. There continue to be no pregnancies to date among patients who had been enrolled in the Essure phase II and pivotal trials. E[acute accent]"With our compelling five year data, Essure has reached an important long-term milestone for clinical study of a medical device, and has reached it with an exceptionally high effectiveness rating that remains consistent over time," commented Mark Sieczkarek, President and Chief Executive Officer of Conceptus. "Essure has withstood the test of time by establishing a long-term efficacy so critical to physicians, payers and patients. For women looking for permanent birth control, we believe that Essure continues to be the best choice from every perspective, including cost, convenience, risk and effectiveness." E[acute accent]Based on past practices, Conceptus estimates that the PMA supplement could take up to six months for FDA action.

E[acute accent]About Essure

E[acute accent]The Essure procedure deploys a soft micro-insert into the fallopian tube through the cervix using a minimally invasive transcervical tubal access catheter. Once in place, the device is designed to elicit tissue growth in and around the micro-insert to form an occlusion or blockage in the fallopian tube. An Essure procedure does not require cutting or penetrating the abdomen and can be performed in a less costly procedure setting without general anesthesia. A woman is able to return home about 45 minutes after the procedure is completed. There is a three-month waiting period after the procedure during which women must use another form of birth control. Essure is 99.80% effective after three years of follow-up.
