<；P>；PROBLEM TO BE SOLVED: To provide an improved catheter for uniform distribution of fluid medication to a wound part within an anatomical region. <；P>；SOLUTION: The catheter for delivering fluid to an anatomical region includes: an elongate tubular catheter body which defines a lumen having a closed distal end, a portion of the catheter body has a plurality of opening parts extended on a side wall of the catheter body to define an infusion section of the catheter thereby； and a tubular sheath which is configured with a porous materia, is disposed to cover the infusion section and extended as long as the length of the infusion section. The tubular sheath and the catheter body include the tubular sheath configured so that the fluid in the lumen goes out from the catheter through the tubular sheath. The pore size of the porous material is less than about 0.5 &mu；. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
