Abstract: An electrocautery device comprises first and second continuous loop electrode structures. The electrodes are typically coupled together at one end, permitting the electrodes to be introduced anteriorly and posteriorly over a uterine body. The electrodes may be clamped together, and radiofrequency energy may be delivered through the clamped electrodes to sever and cauterize blood vessels, tubular structures, and ligaments which connect the uterine body to surrounding tissue structures. The mobilized uterine body may then be removed by conventional hysterectomy.

Abstract: Uterine artery occlusion is performed for the treatment of uterine fibroid using a tool which is introduced through the vaginal wall to the exterior of the uterus. The tool carried clamping elements which may be positioned over the uterine artery. Electrodes or other energy applying devices on the clamping elements may be used to deliver energy to seal the uterine artery. Optionally, the tool may carry ultrasonic, visual, or proximity sensors for detecting the presence of the uterine artery prior to delivering energy.

Abstract: Transvaginal hysterectomy is performed by mechanically engaging and extracting a uterus through opposed cutting and cauterizing elements. The cutting and cauterizing elements are typically provided on an expandable frame which may be positioned at the vaginal os. An associated traction device may be used to pull the uterus through the frame at a controlled rate.
