Essure hysteroscopic sterilization: results based on utilizing a new coil catheter delivery system

Study objectiveTo assess the safety and placement effectiveness of a new delivery catheter for the Essure micro-insert hysteroscopic sterilization system.DesignProspective, multicenter, single-arm clinical study. (Canadian Task Force classification II-3).SettingHospital-based clinical research centers.PatientsOne hundred two women of reproductive age and proven fertility.InterventionA new coil catheter delivery system was used for micro-insert placement.Measurements and main resultsThe 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.ConclusionThese 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.Kerin, John F. ; Munday, David N. ; Ritossa, Martin G. ; Pesce, Andrew ; Rosen, Davi
