FIGURE 1 View of microinserts in one patient at second-look hysteroscopy performed 28 months postprocedure. (A) Hysteroscopic appearance of the trailing end of the right microinsert at completion of placement. Three coils extend from the right ostium. (B) Second-look hysteroscopy in the same woman 28 months later demonstrates complete tissue encapsulation of the intrauterine portion of the right microinsert. (C) Hysteroscopic view of left microinsert at completion of placement shows three coils extending from the left ostium. (D) Second-look hysteroscopy demonstrates tissue encapsulation, leaving only the tip of one coil remaining visible on the left. Kerin. IVF pregnancy after Essure® sterilization. Fertil Steril 2007.

FIGURE 2 Ultrasound scan following ET and conception. (A) Transverse, transvaginal ultrasound image at 11 weeks of gestation shows the gestational sac, which contains a viable fetus. The left and right echogenic microinserts traverse the gravid uterus in the region of the intramural tubes. The gap between the proximal ends of the microinserts and the pregnancy sac is approximately 10 mm wide, and contains placental tissue. (B) A line drawing highlights the spatial relationships between the echogenic microinserts and the pregnancy sacs. The arrows in (A) and (B) indicate the locations of the microinserts. Kerin.
