apparatus and method for delivering a fluid into a body cavity is provided. Apparatus so as to communicate with the internal fluid delivery lumen of the inflatable infusion part, a proximal end and a distal end, a fluid delivery lumen extending from the proximal end of the catheter to pass through the port of the distal portion, and a far- position and may include a catheter comprising a partial inflatable injection parts. In use, the distal end of the catheter with an inflatable implanted components of the contracted condition, the lumen or is introduced into the conduit, inflatable implanted components are expanded in the inflated state, lumen or or conduit partially completely closed, also, while the expanded state of the inflatable injection parts is maintained, lumen or fluid from the catheter is injected proximal to the inflatable injection parts in conduit.BACKGROUND 3A~3G流体を体腔中に送達する装置及び方法が提供される。装置は、可膨張性注入部品の内部が流体送達内腔と連通するように、近位端と遠位端、カテーテルの近位端から遠位部分の通過ポートへ伸びる流体送達内腔、及び遠位部分の可膨張性注入部品を含むカテーテルを含むことができる。使用中、収縮状態の可膨張性注入部品を備えるカテーテルの遠位端は、内腔又は導管中に導入され、可膨張性注入部品は膨張状態に膨張され、内腔又は導管を部分的に又は完全に閉塞し、また、可膨張性注入部品の膨張状態が維持される間、流体がカテーテルから内腔又は導管中の可膨張性注入部品の近位に注入される。【選択図】図3A~3G
