Zusammenfassung:PROBLEM TO BE SOLVED: To provide a catheter used for introduction and removal of fluids from a human body.SOLUTION: The catheter comprises as component parts thereof a catheter body, a juncture hub, at least one extension line and at least one connector, each of the component parts comprising an exterior surface, at least one lumen having an intraluminal surface and a bulk polymer. The intraluminal or external surface of a first of the component parts and the exterior or intraluminal surface of a second of the component parts comprise a hydrophilic polymer layer thereon having an average dry thickness of at least about 50 nm, and the first and second component parts comprise bulk polymers having different chemical compositions.SELECTED DRAWING: None 【課題】流体の導入および人体からの除去に使用されるカテーテルの提供。【解決手段】カテーテル本体、接合ハブ、少なくとも1つの延長ラインおよび少なくとも1つのコネクターをその構成部分として備えるカテーテルであって、前記構成部分のそれぞれが、外側表面、内腔内表面を有する少なくとも1つの内腔およびバルクポリマーを備え、第1の前記構成部分の内腔内または外側表面、および第2の前記構成部分の外側または内腔内表面が、少なくとも約50nmの平均乾燥厚さを有する親水性ポリマー層をそれらの上に備え、かつ前記第1および第2の構成部分が異なる化学組成を有するバルクポリマーを備えることを特徴とする、カテーテル。【選択図】なし
