A needle driving apparatus for sternal closure following sternotomy. Accessory elements include: 1) a straight surgical needle absent attached suture and 2) a separate suture carrying small cylinders at opposing ends. Apparatus provides a dual capability of 1) needle penetration of sternum from top surface and 2) precise positioning of cylinder at undersurface of sternum. The apparatus is a handled framework supporting a rachet type drive assembly which includes a lever, a pawl, biasing springs and a toothed arm which carries a needle. A framework extension carries a socketed fixture. The fixture precisely positions a cylinder and its suture in the socket. When the lever is taken up by hand, motion is imparted to the arm and needle. The needle penetrates the sternum, then the cylinder, where it becomes locked therein by friction. Retrograde extraction of needle (using a conventional needle driver) delivers the suture by shuttle action to its desired position, atop the sternum. Repetition on the procedure described, on the opposing side of the sternum completes the placement of a single suture.

Molded body armor panels conformed to fit individual torsos based upon gender or, in custom applications, individual features of a particular male or female torso. The individual body panels are constructed of multiple layers of twill or other unconventional long float woven ballistic fibers with each layer impregnated with a curable adhesive. Additional reinforcement may be supplied in appropriate areas, such as breasts, spine, sternum and edges. The multiple impregnated layers of fabric are placed within a mold conforming to the particular torso contour desired. The long floats of the fabric allows the layers to stretch or compress as required to the particular shape desired. The adhesive is cured in the mold under low heat and low pressure, binding the layers of fabric together, as well as binding the conformed yarns of each individual layer in permanent contour. Interior and exterior coverings for comfort and appearance may be supplied.
