Description
本発明はまた、カテーテルを製造するための方法に関し、該方法は、ステンレス鋼、タングステン及びこれらの組合せのいずれかを含み、且つ、1センチメートル当たり24乃至118の交差箇所となる均一なブレイド密度を有する管状の補強ブレイドを提供する工程と、前記管状の補強ブレイドに湾曲部を形成する工程と、前記湾曲部が形成された管状の補強ブレイドに焼きなましを施す工程と、焼きなましを施された前記湾曲部が形成された管状の補強ブレイドを第1管状部材上に配置する工程と、第2管状部材を焼きなましを施された前記湾曲部が形成された管状の補強ブレイド上に配置する工程とからなり、焼きなましを施された前記管状の補強ブレイドに形成された湾曲部は、完成したカテーテルが所望の形状を維持するように、前記第2管状部材が該管状の補強ブレイド上に配置されてもその形状を保持することを特徴とする。
当業者には、本発明が、本明細書において記載され意図された特定の実施例以外にも、様々な形態で実施できることが理解されるであろう。従って、形状や細部における変更は、本発明の範囲及び精神から逸脱することなくなされたものである。
好適なカテーテルシャフト構造及び材料の他の例は、米国特許第5569218号明細書、第5603705号明細書、第5674208号明細書、第5680873号明細書、第5733248号明細書、第5853400号明細書、第5860963号明細書及び第5911715号明細書に記載されており、これら特許文献に開示された内容は本願においても開示されたものとする。
