A hemodialysis catheter, comprising: an elongated body extending along a longitudinal axis, a first distal end region having a first inner side and terminating in a first tip opened to a first lumen extending continuously along both said elongated body and said first distal end region, and a second distal end region having a second inner side and terminating in a second tip opened to a second lumen extending continuously along both said elongated body and said second distal end region; said first tip includes a first tip edge extending from a first tip tubular wall and surrounding a first tip opening, and said second tip includes a second tip edge extending from a second tip tubular wall and surrounding a second tip opening, said first inner side contacts said second inner side and said first and second distal end regions are separated with each other at a junction along a splitting plane without forming gap therebetween along a transverse plane being orthogonal to said splitting plane, said first tip tubular wall has a first flat surface and said second tip tubular wall has a second flat surface facing the first flat surface, said first flat surface and said second flat surface are parallel to said splitting plane; characterized in that said first tip tubular wall includes a first outer groove and a first inner groove merging into said first tip edge, and said second tip tubular wall includes a second outer groove and a second inner groove merging into said second tip edge, wherein said first inner groove extends along said first inner side and opposing said first outer groove, and said second inner groove extends along said second inner side and opposing said second outer groove. an elongated body extending along a longitudinal axis, a first distal end region having a first inner side and terminating in a first tip opened to a first lumen extending continuously along both said elongated body and said first distal end region, and a second distal end region having a second inner side and terminating in a second tip opened to a second lumen extending continuously along both said elongated body and said second distal end region; said first tip includes a first tip edge extending from a first tip tubular wall and surrounding a first tip opening, and said second tip includes a second tip edge extending from a second tip tubular wall and surrounding a second tip opening, said first inner side contacts said second inner side and said first and second distal end regions are separated with each other at a junction along a splitting plane without forming gap therebetween along a transverse plane being orthogonal to said splitting plane, said first tip tubular wall has a first flat surface and said second tip tubular wall has a second flat surface facing the first flat surface, said first flat surface and said second flat surface are parallel to said splitting plane; characterized in that said first tip tubular wall includes a first outer groove and a first inner groove merging into said first tip edge, and said second tip tubular wall includes a second outer groove and a second inner groove merging into said second tip edge, wherein said first inner groove extends along said first inner side and opposing said first outer groove, and said second inner groove extends along said second inner side and opposing said second outer groove. <EOS>
