Title
(JA) 動力学的隔離加圧システム
Abstract
(JA)

患者体内の標的部位に治療用薬剤を送達する方法により、全身作用を低減させた状態で効率的に薬剤を送達する。同方法は、第一の流体圧の流体が通過できる壁を少なくとも1つ有する非穿孔送達装置を提供する段階を含む。非穿孔送達装置は、標的部位に対して放射状の流体力を提供するように配置される。少なくとも1つの治療用薬剤を含む流体は、第一の流体圧で治療用薬剤送達装置に供給される。流体は、送達装置の少なくとも1つの壁を通過し、送達装置の外側に第二の流体圧で半閉鎖空間を作り出す。送達装置は、半閉鎖空間とその中に配置された流体とに対して放射状の流体力を印加し、同時に、送達装置を通過する流体が標的部位の半閉鎖空間内で第二の流体圧を保つことを容易にする。流体は、流体圧および滞留時間によって変更可能である治療効果をもたらすのに十分な量で実質的に均一に標的部位へと分布される、少なくとも1つの治療用薬剤を含む。
