In various embodiments of the invention, the components can include a hemostatic vacuum cup which can utilize ancillary or self-contained vacuum generation, and a therapeutic agent which is supplied prior, simultaneously or subsequent to the application of a vacuum with the ultimate aim of slowing or arresting the flow of blood in a bodily tissue or organ. The invention relates to a hemostatic vacuum cup which can utilize ancillary or self-contained vacuum generation. The cup produces a hemostatic effect by the physical application of the device upon a traumatized tissue site and through the delivery of an agent, such as one that assists in hemostasis, antinociception, coagulation, sterilization, or other effective wound healing agents including antibiotics, antiseptics and antioxidants. The cup can be adapted to deliver the therapeutic agent, by methods integral to the vacuum cup. The therapeutic agent can be delivered in the form of a sponge, cellulose or other filter material.

1. A device for compressing a tissue surface comprising: a vacuum cup including an outer perimeter adapted to attach to the tissue surface when a negative pressure is applied in the vacuum cup, a top and a wall including a plurality of parallel ridges extending lengthwise from the top of the cup toward the outer perimeter aligned perpendicular to the tissue surface, where the outer perimeter, the wall and the top define two or more cavities, where the plurality of ridges assist one or both deformation and collapse of the wall when the negative pressure is applied in the vacuum cup, where the outer perimeter is adapted to be positioned proximal to the tissue surface; anda vacuum source adapted to apply the negative pressure in the vacuum cup, where activation of the vacuum source evacuates air out of the vacuum cup such that when the outer perimeter is brought into contact with the tissue surface a negative pressure is generated in the vacuum cup which results in one or both the deformation and collapse of the wall and results in compression of the tissue surface. 2. The device of claim 1, where the tissue surface is a site of trauma. 3. The device of claim 2, where the compression of the tissue surface assists healing. 4. The device of claim 1, where the vacuum cup wall is adapted to controllably collapse on application of the negative pressure. 5. The device of claim 4, where collapse of the vacuum cup wall applies inward radial pull on the tissue surface. 6. The device of claim 4, where collapse of the vacuum cup wall creates one or both an axial compression and a radial constriction to the tissue surface. 7. The device of claim 4, where rate of the collapse of the vacuum cup wall is controlled by the negative pressure applied. 8. The device of claim 1, where the vacuum cup wall is constructed with a plurality of thicknesses corresponding to the plurality of ridges. 9. The device of claim 8, where the plurality of thicknesses of the vacuum cup wall assists in controlling one or both deformation and collapse of the vacuum cup wall under the negative pressure. 10. The device of claim 1, further comprising one or more of a membrane, a bead, a platform, a base and a cavity adapted for administering a therapeutic agent to the tissue surface. 11. The device of claim 10, further comprising a flexible bellows integral with the vacuum cup. 12. The device of claim 10, further comprising a relief valve to assist in controlling the negative pressure in the vacuum cup. 13. A device for administering a therapeutic to a tissue surface comprising: a vacuum cup including an outer perimeter, a wall and a top, where the outer perimeter includes an inset positioned near the edge of the outer perimeter, where the outer perimeter is adapted to be positioned proximal to the tissue surface;a bead adapted to be inserted in the inset, where the inset and the bead administer a therapeutic agent to the tissue surface via the exterior surface of the bead; anda vacuum source adapted to apply negative pressure inside the vacuum cup, where the negative pressure deforms the wall in a controlled manner to administer the therapeutic agent to the tissue surface. 14. The device of claim 13, where an adhesion agent is associated with the outer perimeter to assist the bead to attach to the tissue surface. 15. The device of claim 13, further comprising a relief valve and a pump to generate a positive pressure, where the pump can supply the positive pressure to the relief valve. 16. The device of claim 13, where the therapeutic agent is one or more of impregnated, coated, sprayed and dispersed on the bead. 17. The device of claim 2, where the application of the negative pressure seals the site of trauma. 18. A device for administering a therapeutic to a tissue surface comprising: a vacuum cup including a wall with a plurality of ridges forming an annular pattern with respect to the cup wall, where the plurality of ridges are perpendicular to the tissue surface and a top;one or more of a membrane, a bead, a platform, a base and a cavity; anda vacuum source adapted to apply negative pressure inside the vacuum cup, where the plurality of ridges assist one or both deformation and collapse of the wall when a negative pressure is applied in the vacuum cup, where the bead administers the therapeutic along the length of the bead. 19. The device of claim 18, where the therapeutic agent is located outside of the device and the wall deforms to bring the top into contact with the tissue surface for administering the therapeutic agent to the tissue surface. 20. The device of claim 18, where the compression of the tissue surface arrests the flow of blood.
