  • Patent number: 9131976
    Abstract: 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.

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. The elastic tube may be set to such a vibrator device so that a predetermined direction of rotation of the roller extends from the side of the base end portion of the elastic tube to the side of the top end portion thereof and 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.

  • Publication number: 20080039790
    Abstract: An elastic tube (40) is connected to the base end portion of a catheter main body (1) having a balloon (2) at its top end portion. When the elastic tube (40) is set at a vibrator device (RP), the end portion side of the elastic tube, projecting outside, works as a margin volume part (40A). A roller (53) of the vibrator device (RP) can have a shut-off state where the elastic tube (40) is pressed and completely closed, and a communication state where the elastic tube cannot be pressed. When the roller (53) is rotated in a predetermined direction with the inside of a route from the balloon (2) up to the elastic tube (40) filled up with a liquid for heating, the liquid in the elastic tube (40) is pressed toward the margin volume part (40A) in the shut-off state, while in the communication state, the pressurized heating liquid in the margin volume part (40A) flows backward to the balloon (2) side. Repeating the pressurizing and the backward flow vibrates the heating liquid in the balloon (2).

  • Publication number: 20040147915
    Abstract: A high-frequency heating electrode 3 and a temperature sensor 4 are disposed within a balloon 2 attached to a distal end portion of a catheter main body 1. With the balloon 2 being in abutment with a pulmonary vein opening 12a, a heating liquid within the balloon 2 is heated by the electrode 3, whereby the pulmonary vain opening 12a is annularly cauterized.
