摘要：
PROBLEM TO BE SOLVED: To provide a catheter having at least a guidewire lumen and a delivery lumen.SOLUTION: The catheter comprises: a longitudinal extending between a proximal end and a distal end a proximal section having at least two parallel extending lumens including a delivery lumen extending from the proximal end to the distal end and a guidewire receiving lumen having a proximal guidewire exit port a reinforcing tubular member located in the proximal section delivery lumen extending from the proximal end to a point distal to the proximal guidewire exit port, the reinforcing tubular member which transitions from relatively rigid at a proximal point to relatively more flexible at a point distal thereto and a distal section having at least a distal section guidewire receiving lumen and a distal section delivery lumen. The distal section guidewire receiving lumen is in fluid communication with the proximal section guidewire receiving lumen and the distal section delivery lumen is in fluid communication with the proximal section delivery lumen. The delivery lumen is defined by an annular space between an outer tubular member and an inner tubular member at the distal section, and the proximal guidewire exit port is located at less than 10 cm or more than 10 cm from the distal end of the distal section of the catheter.COPYRIGHT: (C)2013,JPO&INPIT【課題】少なくともガイドワイヤ孔と配送孔を有するカテーテルを提供する。【解決手段】近位端と遠位端間に延在する長手、及び近位端から遠位端まで延在する配送孔と近位ガイドワイヤ出口ポートを有するガイドワイヤ受け孔とを含む少なくとも二つの平行に延びた孔を有する近位部、近位端から近位ガイドワイヤ出口ポートに対して遠位点に延びた近位部配送孔内に配置され、かつ近位点から遠位点へ相対的に硬直から柔軟へ移行する強化管状部材、ならびに少なくとも遠位部ガイドワイヤ受け孔と遠位部配送孔を有する遠位部を含み、遠位部ガイドワイヤ受け孔が近位部ガイドワイヤ受け孔と流体連通し、遠位部配送孔が近位部配送孔と流体連通し、配送孔は遠位部で外管状部材と内管状部材との間の環状スペースによって形成され、かつ近位ガイドワイヤ出口ポートはカテーテルの遠位部の遠位端から10cm未満または10cmを超えて配置されているカテーテル。【選択図】図1
