Devices and methods for achieving hemostasis and leakage control in hollow body vessels such as the small and large intestines, arteries, and veins as well as ducts leading to the gall bladder and other organs. The devices and methods disclosed are especially useful in the emergency, trauma surgery or military setting, and most especially during damage control procedures. In such cases, the patient may have received trauma to the abdomen, extremities, neck or thoracic region. The devices utilize removable or permanently implanted, broad, soft, parallel jaw clips with minimal projections to maintain vessel contents without damage to the tissue comprising the vessel. These clips are applied using either standard instruments or custom devices that are subsequently removed leaving the clips implanted, on a temporary or permanent basis, to provide for hemostasis or leakage prevention, or both. These clips overcome the limitations of clips and sutures that are currently used for the same purposes. The clips come in a variety of shapes and sizes. The clips may be placed and removed by open surgery or laparoscopic access.

1. A method of achieving wound closure in a body vessel or lumen comprising the steps of: accessing a wound in a body vessel or lumen;providing a clip having at least two jaws, wherein the clip comprises at least two tabs rotationally connected at a single hinge;moving the tabs to open the jaws of the clip;applying said clip to the body vessel or lumen;closing the jaws of the clip to treat spillage of contents from the wound in the body vessel or lumen, wherein the jaws of the clip are spring biased closed; andfolding the tabs back onto the jaws of the clip to substantially reduce the projection of the tabs away from the clip. 2. The method of claim 1 wherein the step of closing the jaws of the clip further comprises the step of limiting pressure applied to the body vessel or lumen by the jaws of the clip to between 2 and 50 mm Hg. 3. The method of claim 1 wherein the step of closing the jaws of the clip comprises compressing the body vessel or lumen with jaws that are ring-shaped. 4. The method of claim 1 further comprising the step of removing the clip from the body vessel or lumen. 5. The method of claim 1 further comprising the step of resorbing the clip from the body vessel or lumen. 6. The method of claim 1 wherein the step of closing the jaws of the clip comprises maintaining approximately parallel tissue-contacting surfaces between the jaws when in the closed position. 7. The method of claim 1 wherein the step of folding the tabs back onto the jaws creates a clip geometry that is substantially atraumatic to surrounding tissue. 8. The method of claim 1 wherein the step of closing the jaws totally occludes the body vessel or lumen. 9. The method of claim 1 wherein the step of closing the jaws partially occludes the body vessel or lumen. 10. The method of claim 1 wherein the step of closing the jaws of the clip further comprises the step of limiting pressure applied to the body vessel or lumen by the jaws of the clip to between 100 and 300 mm Hg. 11. The method of claim 1 wherein the step of closing the jaws totally occludes and seals both ends of a completely severed vessel. 12. The method of claim 1 wherein the step of closing the jaws comprises compressing said tissue surrounding the wound with jaws that have an opening in a central region. 13. The method of claim 1 further comprising the step of grasping the tabs extending from the clip using a grasping instrument.
