Abstract
【課題】 酸化物の付着を抑えた生体内留置部材を、高い製造効率にて製造できる製造方法を提供する。
【解決手段】 1次コイルCL1をマンドレル11で加工することで、生体内留置部材となる2次コイルCL2を製造する場合、1次コイルCL1を巻き付けるマンドレル11は、表面に、1次コイルCL1を収める螺旋溝12を有しており、その螺旋溝12の少なくとも一部における溝ピッチPが、1次コイルCL1の外径Dに対して、90%以上99%以下である。
【選択図】 図1
Description
実施の一形態について、図面に基づいて説明すれば、以下の通りである。なお、便宜上、ハッチングや部材符号等を省略する場合もあるが、かかる場合、他の図面を参照するものとする。
なお、このような1次コイルCL1のサイズは、特に限定されるものではないが、例えば、外径(φ)は、0.200mm以上0.500mm以下であると好ましい。また、1次コイルCL1が形成された後、その1次コイルCL1の内腔に、金属線材またはポリマー線材で形成された伸張防止用線が配置されてもよい。
例えば、2次加工での加熱温度が550℃以下であっても、図2に示すように、密巻き2次コイルCL2は完成する。
実施の形態2について説明する。なお、実施の形態1で用いた部材と同様の機能を有する部材については同一の符号を付記し、その部材の種々説明を省略する。
12 螺旋溝
P 溝ピッチ
Q 溝ピッチ
D 1次コイルの外径
CL1 1次コイル
CL2 2次コイル[生体内留置部材]
Claims (2)
