New patent application published for: CATHETER

A catheter, including: a hollow shaft having a distal end that includes a first section extending substantially linearly and a second section on a distal end side of the first section. The second section includes a first curved region and a second curved region, less rigid than the first curved region, on the more distal end side than the first curved region. A virtual plane on the axis of the hollow shaft forms a boundary, and spaces on both sides of the virtual plane define a first area and a second area. The first curved region and the distal end of the catheter are in the first area. The second curved portion is in the second area. A distance from the distal end of the catheter to the virtual plane is larger than a distance from the first curved portion to the virtual plane.
