title: A new compound curved needle for intradermal suture closure.
abstract: A new compound curved needle has been designed and developed for intradermal suture closure from a unique stainless steel alloy, American Society of Testing Materials (ASTM) 45500. This needle has a short, straight, sharpened point with a reverse cutting edge, followed by a curved distal section. Despite its geometry, it exhibited a similar resistance to bending and breakage as did a curved needle with a single radius of curvature manufactured from the same alloy. The design of this new needle enabled the physician to pass it through the dermis with a greater accuracy to a controlled depth and length of bite than curved cutting edge needle with a single radius of curvature.
