A catheter of the invention includes an elongated flexible tubular main body; a plurality of manipulation wires inserted through the tubular main body and having tips connected to a distal part of the tubular main body; a manipulation-part main body provided at a base end of the tubular main body; and a bending manipulation part. The bending manipulation part has an engagement part engaging with base ends of the manipulation wires, and individually applies pulling force to the plurality of manipulation wires through pulling operations so as to bend the distal part of the tubular main body. The bending manipulation part is provided so as to be movable with respect to the manipulation-part main body. The path lengths of the plurality of manipulation wires from the tips thereof to the engagement part are simultaneously increased or decreased when the bending manipulation part and the manipulation-part main body move relative to each other.

Catheter, catheter manipulation part, and catheter manufacturing method

The present invention provides a sheath for gastrostoma (), a sheathed dilator, a gastrostomy catheter kit and a method of splitting a sheath for gastrostoma. The sheath for gastrostoma () includes a sheath body () in which a gastrostomy catheter () is inserted and a handle (). The sheath for gastrostoma () lowers the insertion resistance of a gastrostomy catheter when inserted in a fistula before insertion of the gastrostomy catheter in the fistula for replacement in the patient's body. According to the invention, a sheath for gastrostoma, a sheathed dilator, a sheath for gastrostoma with insertion aid, a gastrostomy catheter kit and a method of splitting a sheath for gastrostoma which can lower the insertion resistance during placement of a catheter in the patient's body, facilitate air supply control of an endoscope and stabilize endoscopic visual field during surgery are provided.
