<p>PROBLEM TO BE SOLVED: To provide a medical catheter capable of suppressing lowering of concentration of a medicine supplied into a lumen.SOLUTION: A medical catheter is inserted into the vicinity of a closed part C inside a vessel V in a state that an expansion member 13 is stored inside an outer tube 11, an inner shaft 12 is advanced to the outer tube 11, and the expansion member 13 is projected in front of the outer tube 11 to expand the expansion member 13 in an outside direction in the radial direction of the outer tube 11. Thereafter, when supplying a gelatinous medicine M to a space between the expansion member 13 and the closed part C through a lumen 12a of the inner shaft 12, blood filled between the expansion member 13 and the closed part C flows through a plurality of flow ports 13c of a sheet member 13b. Further, when advancing the expansion member 13 together with the outer tube 11 and the inner shaft 12, only the gelatinous medicine M is pressed in toward the closed part C.</p> |
