The wire which has possessed with the outer part shell and the core. The core at least the 1st it does with the 1st core material plural core parts and, includes with the core part which is done with the 2nd plural 2nd core materials which differ from the 1st core material. The 1st and 2nd core part periodic is arranged alternately alongside the wire. As for the outer part shell, doing with the metal like the biological compatibility metal, in order to offer periodic material quality alongside the wire, it does the core part, with the material which differs. Although the wire, although the first pulling extending of 1 or more is made to receive to wire constitution, in order continuously to make wire constitution, inserts the core part in the outer part shell, on the one hand, the wire pulls and extends and closes the outer part shell in the core part by type being pulled, in order continuously, in order for density to contact high mutually with the outer part shell and the core part, to maintain the core part, it is produced by applying compression to the core part of high-level side of type. As for the wire which it occurs then, the pulling extending of the plural finishes is received. Illustrate use of the wire, for example in vivo heating system, the sunea device and in vivo positioner which operate thermally, includes the medical device like sutento, and organizational foothold.< Selective figure >Figure 1A外側シェルとコアとを有しているワイヤ。コアは、第1のコア材料でできている少なくとも第1の複数のコア部分と、第1のコア材料と異なる第2の複数の第2のコア材料でできているコア部分とを含む。第1および第2のコア部分は、ワイヤに沿って周期的な交互に配置される。外側シェルは、生物学的適合性金属のような金属でできていて、コア部分は、ワイヤに沿って周期的な材料特性を提供するため、異なる材料でできている。ワイヤは、ワイヤ構成に1以上の最初の引き伸ばしを受けさせるのに続いてワイヤ構成を作るため、コア部分を外側シェルに挿入し、一方で、ワイヤが引き伸ばし型によって引っ張られてコア部分に外側シェルを閉じるのに続いて、外側シェルとコア部分との間で密度が高く互いに接触するようにコア部分を維持するため、型の上流側のコア部分に圧縮力を適用することによって製造される。生じたワイヤはそれから、複数の仕上げの引き伸ばしを受ける。ワイヤの例示的な用途は、例えば生体内加熱装置、熱的に作動するスネア装置、生体内位置決め装置、ステント、および、組織足場のような医療装置を含む。【選択図】図1A
