Abstract

A compression and ligation device includes a pair of jaws including one or more Doppler chips oriented to send and receive Doppler signals across the jaws, to assist a practitioner in determining whether or not a uterine artery is between the jaws. A suture leader with an attached suture can be pushed through a channel on one of the jaws, through tissue behind the uterine artery, into another channel on the other jaw, and proximally out the device so that the practitioner can ligate the artery and effect hemostasis.

Claims

1. An intravaginal occlusive device for occluding a uterine artery of a female human patient comprising:

a. a first elongated member having a first jaw with a distal end, a first ligature guide formed on the first jaw, a pivoted proximal end and an inner surface between the proximal and distal end which forms a tissue receiving recess and having a handle extending proximal to the pivoted proximal end;

b. a second elongated member having a second jaw with a distal end, a second ligature guide formed on the second jaw, a pivoted proximal end and an inner surface between the proximal and distal end and having a handle extending proximal to the pivoted proximal end; and

c. at least one Doppler crystal attached to the distal end of at least one of the first or second jaws having a direction of view toward the distal end of the other jaw when in a closed configuration to detect a uterine artery disposed between the distal ends of the first and second jaws.

2. A device in accordance with claim 1, wherein the at least one Doppler crystal is releasably attached to the one of the first and second distal end faces.

3. A device in accordance with claim 1, wherein the at least one Doppler crystal is integrally formed in the one of the first and second distal end faces.

4. A device in accordance with claim 1, wherein the at least one Doppler crystal comprises at least one Doppler crystal attached to each of the first and second distal end faces.

5. A device in accordance with claim 1, wherein the at least one Doppler crystal comprises a plurality of Doppler crystals attached to each of the first and second distal end faces.

6. A device in accordance with claim 1, wherein the at least one Doppler crystal comprises a plurality of Doppler crystals attached to the one of the first and second distal end faces.

7. A device in accordance with claim 1, wherein

the first ligature guide has a proximal opening, a distal opening, and a lumen extending between the proximal and distal openings;

and

the second liguature guide has a proximal opening, a distal opening, and a lumen extending between the proximal and distal openings.

8. A device in accordance with claim 7, wherein the first ligature guide distal opening and the second ligature guide distal opening are oriented toward each other when the jaws are in a closed configuration.

9. A device in accordance with claim 7, further comprising:

a suture leader sized and configured to pass through the first ligature guide lumen and the second ligature guide lumen; and

a length of ligation material attached to the suture leader.

10. A device in accordance with claim 1, wherein said inner surfaces of both the first and second jaws define tissue receiving recesses.

11. A device in accordance with claim 1, wherein at least one of the first and second jaws is C-shaped.

12. A device in accordance with claim 10, wherein both of the first and second jaws are C-shaped.

13. A method of occluding a uterine artery of a female human patient, the patient having a uterus, a cervix with a cervical os, and a vaginal wall with a vaginal formix, comprising:

a. providing a compressing member comprising,

i. a first elongated member having a first jaw with a distal end, a first ligature guide on the first jaw, a pivoted proximal end and an inner surfaces between the proximal and distal end which forms a tissue receiving recess and having a handle extending proximal to the pivoted proximal end;

ii. a second elongated member having a second jaw with a distal end, a second ligature guide on the second law, a pivoted proximal end and an inner surface between the proximal and distal end and having a handle extending proximal to the pivoted proximal end; and

iii. at least one Doppler crystal attached to the distal end of at least one of the first or second laws having a direction of view toward the distal end of the other jaw when in a closed configuration to delect a uterine artery disposed between the distal ends of the first and second jaws;

b. advancing the compressing member within a patient'"'"'s vagina toward a region of the patient'"'"'s vaginal fornix adjacent to a uterine artery until the compressing member reaches the vaginal fornix;

c. manipulating the compressing member effective to distend the vaginal wall at the vaginal fornix adjacent to and on two substantially opposite sides of the uterine artery by the first and second laws;

d. pressing a portion of the vaginal fornix wall with the first and second jaws of the compressing member and closing the jaws to detect the underlying uterine artery; and

e. passing ligature through one of the ligature guides, through the tissue between the closed jaw distal to the uterine artery and through the other ligature guide, and tightening the ligature about the uterine artery so as to occiude the uterine artery.

14. A method in accordance with claim 13, further comprising sensing blood flow through the uterine artery with at least one Doppler crystal having a direction of view.

15. A method in accordance with claim 14, wherein said direction of view comprises a direction along a line passing through two substantially opposite sides of the uterine artery, and wherein the step of sensing blood flow through the uterine artery comprises sensing blood flow along said direction of view.

16. A method in accordance with claim 14, wherein the ligature at least partially occludes the uterine artery for a therapeutically effective time after the at least one Doppler crystal indicates that blood flow through the uterine artery has stopped.

17. A method in accordance with claim 13, wherein the uterine artery is at least partially occluded by compressing the uterine artery between two end faces of the two pivoting jaws.
