Abstract
OBJECTIVE: To evaluate placement efficacy and reliability of a an intratubal occlusion device for permanent contraception and to assess tolerability and overall satisfaction. METHODS: Seven hundred seventy women with known parity were recruited to participate in a prospective, multicenter study. Bipolar, low-level radiofrequency energy delivery and porous silicon inserts were used. Inserts were placed bilaterally in the fallopian tube lumen. Subsequent bilateral occlusion was assessed with hysterosalpingography. RESULTS: Overall, bilateral placement success was achieved in 611 of 645 women (95%). Bilateral occlusion was confirmed in 570 of 645 (88.4%). The 1-year pregnancy prevention rate as derived with life-table methods was 98.9%. CONCLUSION: This transcervical sterilization system offers an effective contraceptive method, which was well tolerated and had a high satisfaction rate. LEVEL OF EVIDENCE: III.
