Abstract:
This multilumen catheter comprises a tubular main body 101 that is surrounded by an outer wall 113 extending from the proximal end to the distal end. The interior of the main body 101 is divided into a plurality of lumens including a first lumen 111 and a second lumen 112 by a partition wall 114 extending in the longitudinal direction. A second opening face 122 at the distal end of the second lumen 112 is positioned at the distal end side of a first opening face 121 at the distal end of the first lumen 111. The outer wall 113 comprises a first outer wall part 115 forming the first lumen 111 and a second outer wall part 116 forming the second lumen 112. The first outer wall part 115 has a first lumen slit 123 that is formed by notching a part of the distal end thereof. The main body 101 has a flexible part 141 having a low hardness. The flexible part 141 is formed so as to include the distal end of the first outer wall part 115 where the first lumen slit 123 is formed.
