Abstract: The present disclosure generally pertains to methods and kits for preparing an ACL repair surgical implant, the method including drilling femoral and tibial bone plugs of a tendon graft to create medial to lateral holes, and passing a braided suture around the tendinous portion of the tibial end, through soft tissue, and out the tibial end. Next, an anterior to posterior femoral hole is drilled, and a flat-braided suture is passed through the femoral medial to lateral hole and, using a bent needle, passed through junctions of the femoral bone plug and the tendinous portion and out through junctions of the tibial bone plug and the tendinous portion on both sides of the graft. Ends of the flat-braided suture are crisscrossed through the medial to lateral tibial hole. A bone-to-bone fixation suture assembly is passed through the anterior to posterior femoral hole.

Abstract: An apparatus for safely purifying hydrogen gas, comprising: a hydrogen gas diffusion cell for filtering hydrogen gas, the cell having an input for hydrogen gas to be purified, an output for ultrapurified hydrogen gas and an output for waste gas, including hydrogen gas and concentrated corrosive agents; an electrical power supply for heating the diffusion cell to an elevated operating temperature; an electrical circuit for detecting hydrogen gas, disposed adjacent the diffusion cell and the input and outputs, and for generating a command signal when hydrogen is detected; an electrically activatable valve disposed in and controlling the hydrogen gas input, operable in response to the command signal; and, an electrical switch for disabling the electrical power supply in response to the command signal, whereby the apparatus will be rendered completely inoperative before explosive levels of hydrogen gas can accumulate.
