Abstract

Devices and methods are disclosed for treating a uterine disorder which receive its blood supply from a uterine artery. In particular, uterine fibroids are effectively treated by occluding the uterine arteries using trans-vaginal, trans-uterine, transrectal, or retroperitoneal approaches. The devices and methods are advantageous because the inventive procedures may be performed by a patient'"'"'s gynecologist in the course of treatment, avoiding the need for referrals to specialist practitioners and for more radical treatments, such as hysterectomies. The methods include both temporary and permanent occlusion of the arteries. A cannula carries an imaging device and a member which will easily penetrate tissue, the member including a device which partially or completely, and temporarily or permanently, occludes a uterine artery.

Claims

1. A therapeutic device for treating a female patient'"'"'s uterine disorder by temporarily occluding the patient'"'"'s uterine artery, comprising:

an elongated cannula having a proximal end and a distal end, wherein the elongated cannula comprises a distal portion adjacent the distal end, a rigid shaft section extending along a longitudinal axis from the proximal end of the elongated cannula toward the distal portion, and a junction disposed between the rigid shaft section and the distal portion, wherein the junction is flexible so that the distal portion is deflectable to one side of the longitudinal axis of the rigid shaft section;

a supporting member extendable from a first surface of the distal portion for deflecting the distal portion to one side of the longitudinal axis of the rigid shaft section, wherein the supporting member comprises a belt having a distal end attached to the distal portion and a proximal end that is movable along the longitudinal axis of the rigid shaft section to bow the belt outwardly for bearing against opposing tissue;

a blood flow sensor positioned adjacent the distal end of the elongated cannula and being adapted for locating the patient'"'"'s uterine artery;

a tissue penetrating member extendable from the distal end of the elongated cannula, the tissue penetrating member including a tissue penetrating cannula having a lumen extending to a distal end thereof and a pressure applying mechanism movable through the lumen of the tissue penetrating cannula between a retracted position and an extended position; and

the proximal end of the elongated cannula being adapted to extend out of the patient.

2. The therapeutic device of claim 1 wherein the blood flow sensor is selected from the group consisting of a CT scanner, a fluoroscope, an X-ray device, an MRI device, a Doppler audio device, a gray scale color 2D Doppler ultrasound device, a landmark system, and combinations hereof.

3. The therapeutic device of claim 1 wherein the tissue penetrating member has a distal end adapted to penetrate tissue.

4. The therapeutic device of claim 1 wherein the distal portion of the elongated cannula is rigid.

5. A method of treating a female patient'"'"'s uterine disorder by temporarily occluding a uterine artery of the patient, comprising:

a. providing a treatment device which has a distal portion with a pair of opposed pressure applying surfaces and which has a blood flow sensor;

b. advancing the treatment device within the female patient;

c. locating the patient'"'"'s uterine artery with the blood flow sensor and placing the opposed pressure applying surfaces adjacent to opposed sides of the uterine artery with the blood flow sensor;

d. temporarily occluding the located uterine artery by at least partially closing the opposed pressure applying surfaces of the treatment device against the opposed sides of the located uterine artery to at least partially occlude the located uterine artery;

e. maintaining the uterine artery occlusion for sufficient time for therapeutic effects on the uterine disorder; and

f. releasing pressure applied to the uterine artery.

6. The method of claim 5, wherein the treatment device penetrates tissue to access a region adjacent the patient'"'"'s uterine artery.

7. The method of claim 6, wherein the tissue penetrated by the treatment device includes abdominal tissue.

8. The method of claim 5, wherein the treatment device is inserted into a body cavity of the patient.

9. The method of claim 8, wherein said body cavity is the patient'"'"'s vaginal canal.

10. The method of claim 8, wherein said body cavity is the patient'"'"'s uterus.

11. The method of claim 8, wherein said body cavity is the patient'"'"'s rectum.

12. The method of claim 8, wherein said body cavity is a peritoneal cavity.

13. The method of claim 5, wherein the blood flow sensor utilized to locate the uterine artery is an ultrasonic transducer.

14. A method of claim 5, wherein the uterine disorder is a uterine fibroid.

15. A method of claim 5, wherein the uterine artery is located with a blood vessel sensor selected from the group consisting of a CT scanner, a fluoroscope, X ray, a MRI device, Doppler audio device, a gray scale color 2D Doppler ultrasound device, a landmark system, and combinations thereof.

16. A method of claim 5, wherein the treatment device is inserted into a body cavity along a path selected from the group consisting of a path along a uterine wall, a path along a vaginal wall, a path along a rectal wall, a path through a uterine wall, a path through a vaginal wall, a path through a rectal wall, and a path into a peritoneal cavity.

17. An intravaginal method for treating a female patient'"'"'s dysfunctional uterus by temporarily at least partially occluding the female patient'"'"'s uterine artery, comprising:

a. providing an elongated occlusion device having on a distal portion thereof at least one pressure-applying member and at least one blood flow sensor;

b. advancing the distal portion of the elongated occlusion device through the patient'"'"'s vaginal canal;

c. locating a uterine artery with the blood flow sensor provided on the distal portion of the occlusion device;

d. placing the at least one pressure applying surface adjacent to the uterine artery with the aid of the blood flow sensor;

e. applying pressure to the located uterine artery with the pressure applying member of the occlusion device to at least partially occlude the located artery;

f. maintaining pressure on the located uterine artery to at least partially occlude the uterine artery temporarily to obtain a therapeutic effect; and

g. releasing pressure applied to the occluded uterine artery.

18. The method of claim 17, wherein the treatment device penetrates tissue to access a region adjacent the patient'"'"'s uterine artery.

19. The method of claim 18, wherein the tissue penetrated by the treatment device includes abdominal tissue.

20. The method of claim 17, wherein the treatment device is inserted into a body cavity of the patient.

21. The method of claim 20, wherein said body cavity is the patient'"'"'s vaginal canal.

22. The method of claim 20, wherein said body cavity is the patient'"'"'s uterus.

23. The method of claim 20, wherein said body cavity is the patient'"'"'s rectum.

24. The method of claim 20, wherein said body cavity is a peritoneal cavity.

25. The method of claim 17, wherein the blood flow sensor utilized to locate the uterine artery is an ultrasonic transducer.

26. A method of claim 17, wherein the uterine disorder is a uterine fibroid.

27. A method of claim 17, wherein the uterine artery is located with a blood vessel sensor selected from the group consisting of a CT scanner, a fluoroscope, X ray, a MRI device, Doppler audio device, a gray scale color 2D Doppler ultrasound device, a landmark system, and combinations thereof.

28. A method of claim 17, wherein the treatment device is inserted into a body cavity along a path selected from the group consisting of a path along a uterine wall, a path along a vaginal wall, a path along a rectal wall, a path through a uterine wall, a path through a vaginal wall, a path through a rectal wall, and a path into a peritoneal cavity.
