Problems solved by technology

Ablation and resection result in considerable CIN clearance (80-90%)
Excision offers the advantage of providing a pathological sample for histological examination, but has the disadvantage of increased surgical complications such as bleeding and cervical incompetence

Embodiment Construction

[0079] Provided herein are embodiments of systems and methods for ablation therapy of epithelial tissue of the female urinary and reproductive systems to treat diseases such as cervical epithelial neoplasia (also known as cervical intraepithelial neoplasia) and early spread neoplastic lesions (cancer). Other exemplary disorders or diseases of the genitourinary tract that can be treated by embodiments of the systems and methods include vaginal intraepithelial neoplasia, endometriosis, radiation vaginitis, rectovaginal fistula, vesicovaginal fistula, or ureterovaginal fistula , and vaginal or cervical vascular malformations (eg, hemangiomas, arteriovenous malformations, or vascular dysplasia).

[0080] An exemplary mode of ablation therapy is to distribute radiofrequency energy to the target area of ​​the lesion. Other sources of ablation energy include ultraviolet, microwave energy, ultrasonic energy, thermal energy delivered from a heated fluid medium, thermal energy delivere...

Abstract

The invention provides a system, devices, and methods for ablating abnormal epithelial tissue of the uterine cervix. Embodiments of an ablation device include an operative head with a support surface adapted to conformably engage and therapeutically contact the cervix, and an energy delivery element on the support surface. The energy delivery element is configured to deliver energy, such as RF energy, to the tissue in a manner that controls the surface area and depth of ablation. The device may further include a shaft and a handle to support the ablation device, and may further include a speculum to facilitate access to the cervix. A system to support the operation of the ablation device includes a generator to deliver energy to the energy delivery element. Embodiments of a method for ablating abnormal cervical tissue include inserting an ablation device intravaginally to contact the cervix, aligning an energy delivery element support surface conformably against a region of the cervix with abnormal tissue, and ablating the tissue.
