  • Tissue, expansion and approximation device
    Patent number: 5618310
    Abstract: A device applies continuous tension to skin adjacent an ulcerative area, to expand and approximate this skin until it covers the ulcerative area. The new device includes a frame which defines a path in which sliders move under the force of a constant tension spring. Each slider includes a hook-like element that engages and pulls the skin until the skin on opposite sides of the ulcerative area comes together. This element is curved, thus defining a plane which is oriented perpendicular to the path of the slider.
