An intravaginal uterine artery occlusion device is used for treating uterine disorders such as fibroids, dysfunctional uterine bleeding, postpartum hemorrhage and the like. A occlusion device has a cervical receptacle with an open distal end for receiving the patients uterine cervix, an elongated shaft having a distal end secured to the closed proximal end of the cervical receptacle, and an inner lumen extending to the distal end of the shaft. The patient's uterine cervix is held within the interior of the receptacle by the application of a vacuum to the interior of the receptacle through the inner lumen of the shaft while the leading edge(s) of the cervical receptacle press against the patient's vaginal fornix to occlude the uterine artery. A blood flow sensor may be provided on the leading edge of the receptacle to aid in locating a uterine artery and to monitor blood flow through the uterine artery.

The invention is directed to instruments and procedures using such instruments for temporarily reducing or terminating blood flow through a female patient's uterine artery to treat post partum hemorrhage (PPH). The uterine artery is occluded by a clamping device which includes a pair of pivotally connected clamping members, with each of the clamping members having a handle and a clamping element at the distal end of the handle. The clamping elements are inclined with respect to the longitudinal axes of the handles at an included obtuse angle between about 120° and about 170°, preferably between about 130° and 160°. An artery locating sensor is provided on the distal end of at least one of the clamping elements. Preferably, the artery locating sensor is a Doppler ultrasound blood flow sensor. After birth, the clamping device is inserted into the female patient's post partum vaginal canal and advanced therein until one of the clamping elements Is in the patient's uterine cervix and the other clamping element is on the exterior of the uterine cervix. The clamping element on the exterior of the patient's uterine cervix is pressed against the patient's vaginal fornix and the clamping device closed so as to occlude the uterine artery disposed within tissue grasped by the clamping device. The clamping device is locked in the closed configuration and maintained in the condition until the patient's uterus is sufficiently clotted up to ensure termination of the hemorrhaging, typically about 5 minutes to about 7 hours.

An apparatus for simulating a female vagina includes a pressure chamber, a vaginal model disposed in a pressure chamber and means to deliver liquid into the vaginal model. The pressure chamber includes an interior, first means to provide fluid pressure to the pressure chamber, and second means to provide localized fluid pressure within the pressure chamber. The vaginal model includes a wall that (1) defines a vaginal lumen extending inwardly from a vaginal opening associated with a bore through an exterior surface of the pressure chamber to vaginal fornices adjacent a cervical port; (2) has an outer surface comprising an anterior vaginal surface and a posterior vaginal surface; and (3) has at least one passage for providing a fluid to the cervical port. Methods for using this apparatus are also disclosed.

A device positioned in the vagina includes a sensor. The sensor data is used to determine whether conditions are met or exist to trigger a therapeutic response by the device. A device for stimulating nerves adjacent to the vagina includes a nerve stimulating element coupled to a body. The neurostimulatory element is positioned and designed to stimulate the bladder plexus, the Frankenhauser plexus and / or the hypogastric plexus. The device may reside in the vaginal vault. Also provided is an implant having a neurostimulatory element in contact with the uterosacral ligament. A device positioned within the vagina may be used to charge the implant's power source, which may be a capacitor.

A method of contraception for a female subject is provided, as well as a contraceptive product and a contraceptive product system. The method includes spraying an amount of a thixotropic contraceptiveproduct that has Bingham fluid characteristics into a subject's vaginal vault, which contraceptive product comprises a viscosity increasing agent in the range of about 4-8% by weight and an aqueous carrier. The thixotropic contraceptive product is sprayed in a manner that forms a barrier configured to prevent spermatozoa from entering a cervix of the subject.
