Abstract

A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprises wrapping a flexible band of a hemostatic device around the wrist of the patient, wherein the hemostatic device also includes a curved plate, a balloon and a marker used to position the balloon at the puncture site, and wherein the flexible band, the curved plate and the balloon are substantially transparent. The wrapping of the flexible band around the wrist of the patient involves wrapping the flexible band around the wrist of the patient while the balloon is in an uninflated state. The wrapping can also take place while an introducer sheath is in place at the puncture site. The method also involves using the marker to position balloon relative to the puncture site such that the balloon overlies the puncture site, introducing a fluid into the balloon and inflating the balloon, and maintaining inflation of the balloon and compression against the puncture site.

Claims

1. A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprising:

wrapping a flexible band of a hemostatic device around the wrist of the patient, the hemostatic device also comprising a curved plate, a balloon and a marker used to position the balloon at the puncture site, wherein the flexible band, the curved plate and the balloon are substantially transparent;

the wrapping of the flexible band around the wrist of the patient comprising wrapping the flexible band around the wrist of the patient while the balloon is in an uninflated state and while an introducer sheath is in place at the puncture site;

using the marker to position balloon relative to the puncture site such that the balloon overlies the puncture site;

introducing a fluid into the balloon and inflating the balloon; and

maintaining inflation of the balloon and compression against the puncture site.

2. The method of claim 1, wherein the marker is positioned to identify a center of the balloon, and wherein the using of the marker to position the balloon relative to the puncture site comprises positioning the marker so that the marker overlies the puncture site.

3. The method of claim 1, wherein the introducer sheath is removed from the puncture site after the inflating of the balloon.

4. The method of claim 1, wherein the flexible band is wrapped around the wrist so that the balloon overlaps a thumb side of the wrist.

5. The method of claim 1, wherein the marker is a greenish color.

6. The method of claim 1, wherein the balloon is a first balloon and the hemostatic device comprises a second balloon positioned between the curved plate and the first balloon.

7. The method of claim 6, wherein the second balloon applies a pressing force to the first balloon that is directed toward substantially a center of the wrist.

8. The method of claim 7, wherein a portion of the first balloon and a portion of the second balloon are joined together, and an opening communicates an interior of the first balloon and an interior of the second balloon.

9. The method of claim 8, wherein a terminal end of the first balloon and a terminal end of the second balloon are connected to the flexible band, the first balloon being connected to the flexible band only at the terminal end of the first balloon, and the second balloon being connected to the flexible band only at the terminal end of the second balloon.

10. The method of claim 6, wherein the marker is located on the second balloon.

11. A method to stop bleeding at a puncture site of an artery on a wrist of a patient comprising:

wrapping a flexible band of a hemostatic device around the wrist of the patient so that the flexible band encircles the wrist of the patient, the hemostatic device also comprising a plate made of a material more rigid than the flexible band and having a curved portion, a balloon and a visually identifiable marker used to position the balloon at the puncture site, the flexible band, the plate and the balloon being substantially transparent so that when the flexible band is wrapped around the wrist of the patient, the puncture site is visible through the plate, through the balloon and through the flexible band, and the marker is visible to position the balloon at the puncture site;

positioning the balloon relative to the puncture site through use of the marker to so that the balloon overlies the puncture site and is situated between the plate and the wrist of the patient;

introducing fluid into the balloon after the wrapping of the flexible band around the wrist of the patient to inflate the balloon so that the balloon applies a compressive force to the puncture site; and

maintaining inflation of the balloon and compression against the puncture site to stop the bleeding from the puncture site.

12. The method of claim 11, wherein the wrapping of the flexible band around the patient'"'"'s wrist is performed while an introducer sheath is positioned in the puncture site.

13. The method of claim 12, wherein the introducer sheath is removed from the puncture site after the inflating of the balloon.

14. The method of claim 11, wherein the balloon is a first balloon and the hemostatic device comprises a second balloon, the method comprising inflating the second balloon after the wrapping of the flexible band around the wrist of the patient.

15. The method of claim 14, wherein the second balloon is positioned between the plate and the first balloon.

16. The method of claim 14, wherein the first balloon is in direct contact with the wrist of the patient when the first balloon is inflated.

17. The method of claim 14, wherein the second balloon applies a pressing force to the first balloon which is directed toward substantially a center of the wrist.

18. The method of claim 14, wherein an opening communicates an interior of the first balloon and an interior of the second balloon so that both the first balloon and the second balloon are inflated by the introduction of the fluid.

19. The method of claim 14, wherein a terminal end of the first balloon and a terminal end of the second balloon are connected to the flexible band, the first balloon being connected to the flexible band only at the terminal end of the first balloon, and the second balloon being connected to the flexible band only at the terminal end of the second balloon.

20. The method of claim 14, further comprising inflating the second balloon after the wrapping of the flexible band around the wrist of the patient.

21. The method of claim 14, wherein the fluid introduced into the first balloon to inflate the first balloon is also introduced into the second balloon to inflate the second balloon.

22. The method of claim 14, wherein the marker is located on the second balloon, and the positioning of the balloon relative to the puncture site through use of the marker comprises positioning the first balloon such that the marker on the second balloon overlies the puncture site.

23. The method of claim 11, wherein the marker is positioned to identify a center of the balloon, and the positioning of the balloon relative to the puncture site through use of the marker comprises positioning the balloon such that the marker overlies the puncture site.

24. The method of claim 11, wherein the balloon is in direct contact with the wrist of the patient when the balloon is inflated.

25. The method of claim 11, wherein the marker is visible through the flexible band and through the plate.
