Abstract
A study was performed to evaluate a new transcervical, Fallopian tube access system for use in falloposcopy procedures without the need for conventional hysteroscopy or uterine distension. Visualization was accomplished by the use of a 0.5 mm falloposcope which was delivered to the Fallopian tube by a new linear everting catheter. The linear everting catheter allows access to the Fallopian tube by means of a flexible, tubular rolling membrane which can safely negotiate the tortuous anatomy from the ostium to the ampulla. Concurrent laparoscopy was performed solely for supervision purposes and not for tubal manipulations in 13 Fallopian tube access procedures in 10 patients. The ostia were visualized in 12 cases and the Fallopian tube was accessed in all 12 without complications. As a precursor for future gamete and embryo transfer procedures, intra-tubal insemination was performed by visualizing the ostia, accessing the Fallopian tubes, and obtaining successful isthmic-ampullary, intra-luminal images.
