Abstract

One aspect of the invention relates to a device for control of hemorrhage from major blood vessels in acute trauma. The device can be a self sizing expandable/collapsible device placed percutaneously across the site of injury and fitted with intravascular imaging to allow visualization of positioning without the need for x-ray equipment or an operating room. The expandable/collapsible device can be tapered to accommodate a large variance in vessel size and can be textured with treads to prevent movement in high flow vessels. The expandable/collapsible device can be placed at the patient'"'"'s bedside, provides for vascular control during definitive repair, and can be removed after said repair.

Claims

1. A catheter for an emergency medic, said catheter comprising:

a flexible, rigid tube, said rigid tube comprising;

an intravascular imaging device for providing real-time imaging of a passageway;

at least one expandable/collapsible device in a collapsed state wherein when said catheter is inserted in a percutaneous fashion into said passageway, and said catheter is guided based on said real-time imaging to an area adjacent to an area of injury, and said expandable/collapsible device is expanded from the collapsed state into an expandable state.

2. The catheter of claim 1 further comprising three balloon assemblies including:

a proximal expandable/collapsible device having a proximal total occlusion device;

a expandable/collapsible device having a middle tubular device; and

a expandable/collapsible device having a distal total occlusion device, such that definitive repair is possible with inflation of said proximal total occlusion device and said distal total occlusion device.

3. The catheter of claim 1 wherein said expandable/collapsible device comprises a total occlusion device to encompass the entirety of the blood vessel lumen.

4. The catheter of claim 1 wherein said expandable/collapsible device comprises a tubular device to provide a center flow channel to provide blood flow while maintaining control of bleeding across an injury.

5. The catheter of claim 1 wherein said expandable/collapsible device comprises a tapered device.

6. The catheter of claim 1 wherein said expandable/collapsible device further comprises tread markings so as to provide traction and stability of said device in blood vessels.

7. The catheter of claim 1 wherein said rigid tube further comprises:

a guidewire endhole;

a wire port at a proximal end; and

a wire port channel disposed between said guidewire endhole and said wire port.

8. The catheter of claim 1 further comprising echogenic etch marks.

9. The catheter of claim 1 wherein said device further comprises tread markings.

10. The catheter of claim 1 Comprising a total occlusion device and tubular device.

11. A method for the intravascular control of hemorrhage from major blood vessels in acute trauma comprising the sequential steps of:

a) providing a catheter having at least one intravascular imaging device for providing real-time imaging of a body passageway and at least one expandable/collapsible device;

b) guiding said catheter into a blood vessel in open or percutaneous fashion to an area adjacent said hemorrhage;

using said real-time imaging as a guide for location of said device without the use of an x-ray, and

c) expanding said device.

12. The method of claim 11 wherein said balloon comprises a total occlusion device said guiding at step b) comprises inserting said total occlusion device past said area of injury.

13. The method of claim 11 wherein said balloon comprises a total occlusion device to block blood flow.

14. The method of claim 11 wherein said balloon comprises a tubular device to permit blood flow.

15. The method of claim 11 wherein said catheter at step a) comprises:

a proximal expandable/collapsible device having a proximal total occlusion device;

a middle expandable/collapsible device having a middle tubular device; and

a distal expandable/collapsible device having a distal total occlusion device,

wherein said guiding a step b) further comprises placing said middle tubular balloon across the injury, and wherein said expanding at step c) comprises expanding said distal total occlusion device, and expanding said tubular device.

16. The method of claim 15 wherein said middle device is tapered

17. The method of claim 15 further comprising the step of collapsing said distal total occlusion device after step c).
