Heating type balloon catheter device, and elastic tube device and vibrator device for the catheter device |
摘要 |
A heating-type balloon catheter device is provided. The catheter device may include a heating-type balloon at a top end portion of a catheter main body and a vibration imparting device connected to a base end portion of the catheter main body. The vibration imparting device may impart vibration to a liquid for heating in the heating-type balloon and include an elastic tube with a base end portion connected to the catheter main body and with a top end portion thereof closed. The elastic tube may be filled with a liquid for heating. A vibrator device having a roller rotating about a rotary shaft at a position offset to the rotary shaft may be provided. A margin volume part which is not pressed with the roller is provided on the side of the top end portion of the elastic tube. |

1. An elastic tube device comprising an elastic tube which is expandable or constrictable in such a manner that tube walls of the elastic tube opposite to each other are caused to be closely attached to each other in a radial direction toward a direction in which the elastic tube is constrictable and that they are allowed to recover to their original shape due to their own elasticity when an external force is released;
wherein the elastic tube has a top end closed and a base end portion constituting a connection part for connecting to a catheter main body; wherein said elastic tube has a margin volume part disposed on a top end side so as not to be pressed by the external force, and wherein a plurality of indicators are disposed on an outer peripheral surface of the elastic tube at a spaced interval in a longitudinal direction of the elastic tube, each of the plurality of indicators being indicative of a size of the margin volume part to be disposed in accordance with a size of a balloon in a heating-type balloon catheter device. |
