Abstract
【解決手段】末梢動脈又は末梢静脈内の血液速度と壁剪断応力を、その動脈又は静脈の全体直径と内腔直径に持続的増大がもたらされるのに十分な水準と十分な期間の間上昇させるためのシステム及び方法が提供される。この方法には、所望の速度でかつ所望の方向に血液を移動させるシステムと方法が含まれる。末梢動脈又は末梢静脈の直径の持続的増大の速度と程度を最適化するために、血液の移動がモニタされ、かつ必要に応じて調節されて、末梢動脈又は静脈内の所望の血液速度と壁剪断応力が維持される。

ポンプは、手動又はソフトウェアプログラムやアプリケーションや他の自動システムで監視および調節が可能である。ソフトウェアプログラムはポンプ速度(毎分のインペラ回転数を含む)を調節して、受容静脈、供与動脈又は供与静脈などの標的血管内の所望の血液速度とWSSを維持することが可能である。あるいはまた、標的血管の直径と、血液ポンプシステム又は標的血管内の血流を定期的にチェックして、標的血管内の所望の血液速度とWSSを維持するように手動調節してもよい。
