Abstract
Description
適切な補助で針の湾曲した外形の低温形状化または室温における形状化を実行すること
課せられた湾曲した外形の幾何学構造を記憶するため、針をその補助において熱処理
を行うこと
その熱処理の間に針に堆積された酸化物の層を取り除くため、化学溶液によって針を清掃すること。
HF+HNO3+H2O2のそれぞれの割合が体積比で1:3:6
の配合組成である。
・上記表1に示されたそれぞれの直径について、異なる曲率半径で合金ワイヤを形成する
・熱処理後、それぞれのサンプルを細長いまたは直線状の姿勢のカテーテル内に挿入し、それからそれが予め定められた曲率半径によりその構成が取れるように配置する
この操作を5回から10回繰り返し、それから復元された形状を評価した。
