An armature-based suction device comprising a convex surface on one side of the device when the device is not in use. A concave surface is located on an opposite side of the device when the device is not in use. The concave surface has a matte finish. The concave surface comprises a perimeter located on an outer edge of the concave surface where the perimeter is non-occlusive when the device is sealed onto a native surface. An annular square-shouldered cross-sectional recess located adjacent to the perimeter. The recess has a main flat surface that is at an acute angle to the concave surface, where the recess is non-occlusive when the vacuum seal is sealed onto a native surface. At least one annular band of soft, resilient, sticky, solid, and non-flowable material is located on the annular square-shouldered cross-sectional recess, and where the device is reusable.
