1. A device for closing a tissue opening, the device comprising:
a compression support frame configured to contact tissue surrounding the tissue opening, the compression support frame comprising an arc-shape with a first linear edge, a second linear edge, an inner peripheral edge extending between the first linear edge and the second linear edge, and an outer peripheral edge extending between the first linear edge and the second linear edge, forming part of a circle having a dimension D1 from a center of the circle to the outer peripheral edge, and forming a continuous arc whose central angle is less than 180° and greater than 45° and whose dimension D1 is constant over the outer peripheral edge, the compression support frame having a top surface disposed in a first plane, a bottom of the compression support frame comprising a plurality of elongate protrusions each having a long axis and a short axis as viewed in a direction perpendicular to the first plane, the long axis of each of the plurality of elongate protrusions extending transversely to the dimension D1 of the compression support frame and extending from the inner peripheral edge to the outer peripheral edge of the compression support frame;
a compression support mounted to and extending from the top surface of the compression support frame, the compression support being rotatably mounted to an elongated protrusion extending from the top surface of the compression support frame, an axis of rotation of the elongated protrusion being perpendicular to the first plane of the compression support frame; and
a tension member selectively slidable in relation to the compression support to rotate the compression support about the compression support frame, wherein the compression support is configured to rotate based on a tension force applied by the tension member, the arc-shape of the compression support frame evenly distributing the tension force applied by the tension member to gather epidermal tissue together.
