Abstract
Description
図面を参照すると、図1及び図2には、円形リング補強材の形態をしている一実施形態が示されており、図3には、使用状態の円形リング補強材が示されている。本発明による不透過性補強リング10は、複合撚り又は編みワイヤ12の複数の巻きを備えていることが分かるであろう。ワイヤはおよそ2回巻かれれているのが望ましいが、他の巻き数が使用されていてもよい。特に図2のワイヤ断面図から理解できるように、ワイヤ12は、ニッケルチタン合金の芯部14、4本のニッケルチタン合金の周辺部素線16、及び2本の金、銀、又は白金などの放射線不透過性ワイヤの素線18を備えている。金、銀、又は白金のワイヤは、複合ワイヤに放射線不透過特性を提供し、ニッケルチタン合金は、複合ワイヤに形状記憶特性を与えている。
