TREATMENT OF THE REPRODUCTIVE TRACT WITH PULSED ELECTRIC FIELDS

Devices, systems and methods are provided for treating conditions of the reproductive tract. A number of conditions can afflict the lining and cell layers deeper within the anatomical structures. For example, cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is a condition involving abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer in situ (CIS). Other conditions include human papillomavirus (HPV)-related cervical disease, various endometrial diseases, acute and chronic cervicitis, and various infections (e.g. trichomoniasis) to name a few. In some embodiments, treatments eliminate diseased, damaged, abnormal or otherwise undesired cells leaving the tissue framework intact. This allows the tissue to regenerate in a normal fashion, avoiding the formation of scar tissue. When the tissue framework is left intact, the framework structure repopulates with healthy cells, regenerating the normal tissue without altering the structural properties.
