A medical device includes an elongated medical device body; a first operating line and a second operating line inserted in an axial direction of the medical device body; and a bending operating part for performing a bending operation of a distal end part of the medical device body by pulling the first and second operating lines, at an intermediate part and a proximal end part in the axial direction of the medical device body, the first and second operating lines extending in parallel so as to be spaced apart from each other in a circumferential direction of the medical device body, and at the distal end part in the axial direction of the medical device body, the first and second operating lines being curved and joined together so as to approach each other in the circumferential direction of the medical device body gradually toward a distal end side.

Medical device

A medical device includes a medical device body, first and second operating lines inserted in axial direction of the device body, and a bending operating part that pulls the operating lines to perform bending operation of a distal end part of the device body. The device body has the distal end part in the axial direction such that the operating lines are gradually curved and approach each other in circumferential direction of the device body toward a distal end side in the distal end part. The device body has a curved region and a parallel region such that in the curved region, the operating lines gradually curve and approach each other in the circumferential direction toward the distal end side and that in a parallel region, the operating lines extend in parallel to each other between the distal end of the curved region and distal ends of the operating lines.

There is provided a laminated body comprising a first resin layer consisting of a first fibrous base material and a resin and a second resin layer consisting of a second fibrous base material and a resin, wherein the first resin layer and the second resin layer are disposed such that the first resin layer and the second resin layer are at least partly positioned in separate regions separated by the center line in a thickness direction of the laminated body; wherein at least one of the first fibrous base material and the second fibrous base material has a bowing region where a bowing region is a region in which a smaller warp/weft crossing angle is less than 90&#xb0; in the fibrous base material; and wherein in the bowing region, an angle formed by a warp of the first fibrous base material and a warp of the second fibrous base material and an angle formed by a weft of the first fibrous base material and a weft of the second fibrous base material, whichever is larger, is 2&#xb0; or less.
