Abstract
Description
通常は、挿入しやすく、その後に目指す目的部位へカテーテルを進めることができるような位置において、患者の血管などの体内管へカテーテルを挿入することにより、医師は、カテーテルを使用して遠隔的に医療処置を行うことができる。この方法により、患者の血管又は血管以外の体内管であれ、ほぼ全ての目的部位に遠隔的に到達させることができる。通常、カテーテルは、上腕部、頸部又は鼠径部近傍の血管等、都合のよい位置において、患者の血管系に挿入される。血管及び血管以外の治療において、カテーテルが進む体内管の経路は、通常蛇行しており、しばしば方向転換を必要とする。また、カテーテルを折り返す必要もある。医師は、カテーテルの基端部分に捻り力を付与して、カテーテルの操舵を補助することがある。操舵を円滑にするために、血管内カテーテルが比較的高いトルク性を有することが望ましい。更に、カテーテルが患者の蛇行する体内構造に適合するために、カテーテルは比較的可撓性を有することが望ましい。カテーテルが比較的高いトルク性を有し、且つ可撓性を保持するという要件は、カテーテルシャフトの壁厚が増加するとトルク性が向上するものの、可撓性を低下させるため、相反する要件となることがある。
