  • Patent number: 9248256
    Abstract: A medical treatment device enables an injection needle to accurately puncture brain tissue at a prescribed position and a drug solution to be injected into brain tissue, while avoiding damage to the brain tissue as the injection needle is handled. The use of the medical treatment device involves inflating a first balloon located on the outside of a catheter, directing a distal portion of a puncture needle, which is located inside the catheter, to outside the catheter through an opening in the catheter, after which the first balloon is deflated and a second balloon is inflated, and moving the catheter towards the brain tissue located on the opening side so that the injection needle projecting from the opening punctures the brain region.

  • Patent number: 8329094
    Abstract: A magnesium alloy having excellent strength and elongation at high temperatures and further having excellent creep characteristics at high temperatures. Also provided is a process for producing the alloy. In producing the magnesium alloy, a magnesium alloy containing yttrium and samarium in respective specific amounts is cast and the resultant cast is subjected to a solution heat treatment, subsequently hot working, and then an aging treatment, thereby reducing the average crystal grain diameter of the structure. In addition, the amounts of the yttrium and samarium in solution in the magnesium matrix are balanced with the number of precipitate particles of a specific size in the crystal grains. The magnesium alloy thus obtained has excellent strength and elongation at high temperatures and further having excellent creep characteristics at high temperatures.
