Abstract

The invention relates to a balloon catheter. The balloon catheter includes a first guiding tube, a second guiding tube, filling tubes and expansible balloons; the first guiding tube includes a guidingcavity; the near end of the second guiding tube is connected to the far end of the first guiding tube, and the inner cavity of the second guiding tube communicates with the guiding cavity; one ends of the filling tubes are connected to the far end of the first guiding tube, and the others are connected to the second guiding tube; and the filling tubes pass through the balloons, and the second guiding tube is squeezed to make the second guiding tube elastically deformed after the balloons are filled. After the far end of the balloon catheter moves to the to-be-opened window part of a covered stent, expanding can be performed on the balloons through the filling tubes, so that the second guiding tube can be squeezed and bended under stress, and therefore, adjusting can be performed on the angles of the far end of the second guiding tube; and thus, location accuracy on the far end of the balloon catheter can be enhanced, and more precise control on the piercing angles of puncturing partscan be achieved.
