Abstract

A method for subdiaphragm hemorrhage control in a patient or for non-invasively enhancing cerebral and myocardial perfusion in a patient includes positioning a moveable surface through the esophagus adjacent the patient'"'"'s esophageal-gastric junction and displacing the moveable surface thereby applying a force posteriorly in the direction of the patient'"'"'s descending aorta sufficient to partially or substantially completely occlude the descending aorta. The moveable surface may be positionable in a lower portion of the esophagus where the esophagus and the aorta pass through the diaphragm or may be positioned in a portion of the patient'"'"'s stomach juxtaposed with the patient'"'"'s descending aorta.

Claims

1. A non-invasive method of subdiaphragm hemorrhage control in a patient, including:

positioning a moveable surface through the patient'"'"'s esophagus at a portion of the patient'"'"'s esophageal-gastric junction that passes through the patient'"'"'s diaphragm; and

displacing the esophageal-gastric junction posteriorly with the moveable surface thereby displacing the patient'"'"'s descending aorta toward the patient'"'"'s vertebral column as a result of binding of the patient'"'"'s esophageal-gastric junction and descending aorta at the patient'"'"'s diaphragm; and

at least partially occluding the descending aorta between the moveable surface and the patient'"'"'s vertebral column.

2. The method of claim 1 including positioning said moveable surface with an elongated member and wherein said applying said force includes moving said moveable surface with a displacement mechanism joining said moveable surface to said elongated member.

3. The method of claim 2 including anchoring said elongated member with an anchoring member in the patient'"'"'s esophagus.

4. The method of claim 2 including anchoring said elongated member with an anchoring member in the patient'"'"'s stomach.

5. The method of claim 2 wherein said displacement mechanism includes parallel linkages supporting said moveable surface in a parallel relationship with said elongated member.

6. The method of claim 2 wherein said moveable surface pivots with respect to said elongated member.

7. The method of claim 1 wherein said moveable surface is defined by a cuff and wherein said displacing the moveable surface includes inflating said cuff sufficiently to at least partially occlude the descending aorta.

8. The method of claim 7 wherein said cuff inflates unidirectionally.

9. A non-invasive method of enhancing cerebral and myocardial perfusion in a patient, including:

positioning a moveable surface through the patient'"'"'s esophagus at a portion of the patient'"'"'s esophageal-gastric junction that passes through the patient'"'"'s diaphragm; and

displacing the esophageal-gastric junction posteriorly with the moveable surface thereby displacing the patient'"'"'s descending aorta toward the patient'"'"'s vertebral column as a result of binding of the patient'"'"'s esophageal-gastric junction and descending aorta at the patient'"'"'s diaphragm; and

at least partially occluding the descending aorta between the moveable surface and the patient'"'"'s vertebral column and thereby increasing central and intracranial arterial pressure.

10. The method of claim 9 including positioning said moveable surface with an elongated member and wherein said applying said force includes moving said moveable surface with a displacement mechanism joining said moveable surface to said elongated member.

11. The method of claim 10 including anchoring said elongated member with an anchoring member in the patient'"'"'s esophagus.

12. The method of claim 10 including anchoring said elongated member with an anchoring member in the patient'"'"'s stomach.

13. The method of claim 10 wherein said displacement mechanism includes parallel linkages supporting said moveable surface in a parallel relationship with said elongated member.

14. The method of claim 10 wherein said moveable surface pivots with respect to said elongated member.

15. The method of claim 9 wherein said moveable surface is defined by a cuff and wherein said displacing the moveable surface includes inflating said cuff sufficiently to at least partially occlude the descending aorta.

16. The method of claim 15 including inflating said cuff unidirectionally.

22. The method of claim 14 wherein said connecting member is a lever.

23. The method of claim 15 including anchoring said elongated member with an anchoring member in the patient'"'"'s esophagus.

17. A non-invasive method of enhancing cerebral and myocardial perfusion in a patient, including:

positioning an inflatable device through the patient'"'"'s esophagus in a portion of the patient'"'"'s stomach juxtaposed with the patient'"'"'s descending aorta and at least partially inflating the inflatable device; and

applying a force in the patient'"'"'s stomach with the at least partially inflated device, including applying said force posteriorly in the direction of the patient'"'"'s descending aorta, said force being sufficient to at least partially occlude the descending aorta and thereby increasing central and intracranial arterial pressure.

18. The method of claim 17 including positioning said inflatable device with an elongated member attached to said inflatable device and wherein said applying said force includes moving said inflatable device in the direction of the patient'"'"'s diaphragm by applying traction to said elongated member.

19. The method of claim 17 wherein said applying a force includes applying a force on an exterior surface of the patient.

20. The method of claim 19 using a belt around the patient'"'"'s thoraco-abdominal region to apply said force.

21. The method of claim 17 including positioning said inflatable device with an elongated member and wherein said applying said force includes moving said inflatable device with a connecting member joining said inflatable device to said elongated member.

24. The method of claim 21 including anchoring said elongated member with an anchoring member in the patient'"'"'s stomach.

25. The method of claim 24 wherein said anchoring member is another inflatable device positioned to react with the patient'"'"'s diaphragm.

26. The method of claim 17 including positioning said inflatable device with an elongated member and wherein said applying a force includes providing a substantially rigid portion of said elongated member and expanding said inflatable device posteriorly from said rigid portion.

27. The method of claim 26 including anchoring said elongated member with an anchoring member in the patient'"'"'s esophagus.

28. The method of claim 26 including anchoring said elongated member with an anchoring member in the patient'"'"'s stomach.

29. The method of claim 28 wherein said anchoring member is another inflatable device positioned to react with the patient'"'"'s diaphragm.

30. The method of claim 29 including defining at least one electrode with at least one of said inflatable devices.

32. The method of claim 31 including defining at least one electrode with said inflatable device.

33. The method of claim 17 including applying said force in synchronism with ventricular contractions of the patient.

34. A non-invasive method of subdiaphragm hemorrhage control in a patient, including:
