Patent number: 9446217Abstract: A catheter that can efficiently transmit a pressing force applied to the distal end of the catheter without breaking at a midpoint of the catheter. The catheter includes a metal tube having a first wall and a second wall disposed in an outer tube, and a reinforcing member that is joined at its proximal end to an outer peripheral surface of the first wall. A distal end of the first wall extends distally beyond a distal end of the second wall and is bent toward the second wall. Thus, the second wall is not provided at a connected portion between the first wall and the proximal end of the reinforcing member, and the reinforcing member having a diameter increased at least by an amount corresponding to a thickness of the second wall can be disposed in the catheter without increasing the diameter of the outer tube.Type: GrantFiled: January 15, 2015Date of Patent: September 20, 2016Assignee: ASAHI INTECC CO., LTD.Inventor: Makoto Nishigishi
