Patent ID: 8915894

Claim:
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; and a 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.
