The invention is directed to an intravaginal uterine artery occlusion device for treating uterine disorders such as fibroids, dysfunctional uterine bleeding, postpartum hemorrhage and the like. A occlusion device has a cervical receptacle or cap with an open distal end for receiving the patient's uterine cervix and 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 elongated 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 or otherwise, while the leading edge(s) of the cervical receptacle press against the patient's vaginal fornix to occlude an underlying or adjacent uterine artery. At least one 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 located uterine artery.

L'invention concerne un dispositif intravaginal d'occlusion d'une artère utérine permettant de traiter les troubles utérins tels que les fibroïdes, les saignements utérins dysfonctionnels, les hémorragies post-partum, et autres troubles semblables. Le dispositif d'occlusion comprend un support ou dispositif cervical présentant une extrémité distale ouverte destinée à recevoir le col de l'utérus de la patiente et une tige allongée présentant une extrémité distale fixée à l'extrémité proximale fermée du support cervical et une lumière interne s'étendant vers l'extrémité distale de la tige allongée. Le col de l'utérus de la patiente est retenu à l'intérieur du support par application d'un vide à l'intérieur du support à travers la lumière interne de la tige, tandis que le ou les bords avant du support cervical viennent en contact avec la voûte vaginale de la patiente pour boucher une artère utérine sous-jacente ou adjacente. Au moins un capteur de flux sanguin peut être situé sur le bord avant du support afin de permettre de localiser une artère utérine et de surveiller le flux sanguin dans l'artère utérine localisée.
