(57) [Summary] [Object] An object of the present invention is to provide a catheter capable of transmitting torque and a method of using the catheter capable of achieving a substantially 1: 1 motion ratio between a proximal end portion and a distal end portion of the catheter. To do. The catheter of the present invention comprises a flexible elongate body, the body comprising a tubular wall having at least one slotted segment, said slot having an angle of less than 360 °. Extending through the tubular wall for the length of an arc of, the body comprising a flexible sleeve surrounding the slotted segment, transmitting rotational torque to the slotted segment to secure the body. It further has a first means for imparting a rotational torque to rotate about the axis and a second means for transmitting a bending force to the tip portion of the main body. |
