Abstract
Description
図1を参照すると、血管内装置10が示されている。血管内装置10は、一般に、カテーテルアダプタ14の遠位端16に連結されたカテーテル12を含む。カテーテル12とカテーテルアダプタ14とは、カテーテルアダプタ14の内腔がカテーテル12の内腔と流体連通するように、一体的に結合される。カテーテル12は、一般に、患者へのカテーテルの挿入に関連する圧力に耐えるのに十分な剛性を有する生体適合性材料を含む。
いくつかの実施形態では、隔壁50は、内面60内に隔壁50をセンタリングするためにチャンネル82とリブ84を備え、且つ遠位チャンバと近位チャンバ64との間に流体の流れを提供する。
