Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inflatable retention system for an enteral feeding tube assembly having a base deployed outside a human body and an indwelling retainer deployed within a lumen or cavity of the body by insertion through a stoma from outside the body.SOLUTION: The inflatable retention system of the invention includes a tube having a proximal end, a distal end, an external tube diameter, and tube walls defining a feeding lumen and an inflation lumen. The retention system also includes an inflatable balloon located at a distal end of the tube in fluid communication with the inflation lumen. The balloon has thin, flexible walls, a predetermined spheroid shape, and a predetermined volume at which a fluid in the balloon is under no pressure such that upon inflation with a fluid in the balloon being pressurized, the balloon assumes a stable spheroid shape and exhibits a substantially linear pressure versus volume curve.SELECTED DRAWING: Figure 2A 【課題】体外に配置される基部及び体外から瘻孔を通じて挿入することにより体腔内に配置される留置固定器具を備えた経腸栄養チューブアセンブリ用の膨張式固定システムを提供する。【解決手段】本発明の膨張式固定システムは、近位端と、遠位端と、チューブ外径と、栄養ルーメン及び膨張ルーメンを画定するチューブ壁部とを有するチューブを含む。本システムはまた、前記チューブの前記遠位端に配置され、前記膨張ルーメンに流体連通されたバルーンを含む。前記バルーンは、薄くてフレキシブルなバルーン壁部と、所定の回転楕円体形状（spheroid shape）と、前記バルーン内の流体が非加圧下にあるときの体積である所定の体積とを有し、前記バルーン内の前記流体を加圧して前記バルーンを膨張させたときに、前記バルーンが安定的な回転楕円体形状をとり、かつ実質的に線形の圧力対体積曲線を示すように構成されている。【選択図】図２Ａ
