Study Objective:
To assess the safety and placement effectiveness of a new delivery catheter for the Essure micro-insert hysteroscopic sterilization system.
Design:
Prospective, multicenter, single-arm clinical study. (Canadian Task Force classification II-3).
Setting:
Hospital-based clinical research centers.
Patients:
One hundred two women of reproductive age and proven fertility.
Intervention:
A new coil catheter delivery system was used for micro-insert placement.
Measurements And Main Results:
The bilateral placement of micro-inserts using the coil catheter delivery system occurred in 100 women out of 102 attempts (98%). The two women who did not have successful micro-insert placement were subsequently shown to have proximal tubal stenotic disease.
Conclusion:
These findings indicate that the introduction of the coil catheter delivery system for Essure hysteroscopic sterilization improves the micro-insert bilateral placement rate when compared with previous studies. It is hypothesized that the coil catheter has superior navigational properties, particularly within tortuous or narrowed tubal lumens.
