Abstract
A device having a tissue-engaging member including a generally concave vacuum compartment. The vacuum compartment defines a contacting peripheral edge for contacting a portion of body tissue. The vacuum compartment also defines two compartment grasping portions. The vacuum compartment is deformable between a first compartment configuration and a second compartment configuration upon the creation of a vacuum having a threshold pressure value within the vacuum compartment. The compartment grasping portions are closer together when the vacuum compartment is in the second compartment configuration then when the vacuum compartment is in the first compartment configuration. A coupling allows fluid coupling of the vacuum compartment to a vacuum source.
