- 12. The intrauterine clamping device of claim 1, wherein an artery location sensor is provided at a distal portion of the clamping element.
- 13. The intrauterine clamping device of claim 12, wherein the artery location sensor is a Doppler ultrasound sensor.
- 14. The intrauterine clamping device of claim 13, wherein the Doppler ultrasound sensor is configured to sense ultrasound energy having a frequency of between about 5 MHz and about 20 MHz.
- 15. The intrauterine clamping device of claim 15, wherein the Doppler ultrasound sensor is configured to sense ultrasound energy having a frequency of between about 6 MHz and about 10 MHz.
- 16. The intrauterine clamping device of claim 1, wherein the clamping element has a length between about 1 and about 6 inches.
- 17. The intrauterine clamping device of claim 1, wherein the clamping member has a length between about 2.5 inches and about 4.5 inches.
- 18. The intrauterine clamping device of claim 1, wherein the distal end of the clamping element is disposed distal to the distal end of the stabilizing member by a distance of about 0.1 inch to about 1 inch.
- 19. The intrauterine clamping device of claim 1, wherein the clamping element has a width of about 0.5 inch to about 3 inches.
- 20. The intrauterine clamping device of claim 1, wherein the clamping element is formed at least in part of a loop-shaped wire frame.
- 21. A system for occluding a female patient's uterine artery, comprising:
a. a uterine artery clamping device which has
i. a clamping member which has an elongated handle at an obtuse angle with respect to the first handle, ii. a stabilizing member which has an elongated handle at an obtuse angle with respect to the second elongated handle; and b. an artery location sensor secured to a distal portion of a clamping member.
- 22. The system of claim 22 wherein the clamping device has a pivotal connection between the clamping member and the stabilizing member so that rotation of the handles about the pivotal connection adjusts spacing between the clamping member and the stabilizing member;
- 23. The system of claim 22 including an elongated signal transmitting member having a proximal end and a distal end and being secured at its distal end to the artery locating sensor and having a connector on its proximal end configured to be connected to a sensor controller.
- 24. The system of claim 21, wherein the artery location sensor is a Doppler ultrasound sensor.
- 25. The system of claim 22 wherein the handles have a locking mechanism to provide a locked configuration effective to retain the clamping member and the stabilizing member in a pressure-applying configuration.
- 26. A method of treating a female patient suffering from a uterine disorder, comprising:
a. providing an intrauterine clamping device having
i. an clamping member which has an elongated handle with a proximal manipulative end; ii. a stabilizing member which has an elongated handle with a proximal manipulative end; iii. a pivotal connection between the clamping member and the stabilizing member so that rotation of the handles about-the pivotal connection adjusts spacing between the clamping member and the stabilizing member; and iv. a blood flow sensor on the distal end of the clamping member; b. introducing the intrauterine clamping device into the patient's vaginal canal, and advancing the device therein until the stabilizing member is disposed within the patient's uterine cervix and the clamping member is disposed about an exterior portion of the patients uterine cervix; c. further advancing the device within the patient's vaginal canal to press the clamping element of the clamping member against a region of the patient's vaginal fornix to fold the tissue of the vaginal fornix over the patient's uterine artery; and d. compressing the handles of the clamping device together to close the clamping member against tissue of the patient's vaginal fornix to at least partially occlude the uterine artery.
- 27. The method of claim 26, wherein the clamping member and the stabilizing member are locked in a closed configuration to at least partially occlude a uterine artery of the patient.
- 28. The method of claim 26, wherein the uterine artery is located by an artery location sensor on a distal end of the clamping member when the clamping member is pressed against a region of the patient's vaginal fornix to fold the tissue of the vaginal fornix over the patient's uterine artery to occlude same.
- 29. The method of claim 28, wherein the artery location sensor is a Doppler ultrasound sensor.
- 30. The method of claim 29, wherein the Doppler ultrasound sensor emits ultrasound toward the uterine artery having a frequency of between about 5 MHz and about 20 MHz.
- 31. The method of claim 29, wherein the Doppler ultrasound sensor detects a change in blood flow in the patient's uterine artery.
- 32. The method of claim 29, wherein the Doppler ultrasound sensor detects a reduction in blood flow in the blood vessel.
- 33. The method of claim 27, wherein the uterine artery is at least partially occluded for a period less than 24 hours.
- 34. The method of claim 27, wherein the uterine artery is at least partially occluded for a period comprising between about 0.5 hours and about 7 hours.
- 35. The method of claim 27, wherein the uterine artery is at least partially occluded for a period comprising between about 0.5 and about 5 hours.
- 36. The intrauterine clamp of claim 2 wherein the connector is a spring.
- 37. The intrauterine clamp of claim 2 wherein the connector is a rack and pinion mechanism.
