Abstract
An angioplasty catheter has a hollow metal tube having a proximal end and a distal end with at least two lumens extending through the tube. Also, the catheter includes a first angioplasty balloon and a second angioplasty balloon attached to the tube near the distal end of the tube, with each of the balloons being in fluid communication with a respective lumen. The balloons are eccentric with respect to the tube, and the first and second balloons have respective first and second lengths and respective first and second inflated diameters. The first length is different than the second length, and the first inflated diameter is different than the second inflated diameter.
Claims13
An angioplasty device which comprises:
- a catheter shaft having a distal segment and a proximal segment, said shaft defining an axis;
- at least two independently inflatable and independently deflatable angioplasty balloons operatively engaged with said distal segment of said catheter shaft, each said balloon defining respective axes and having respective walls, respective lengths, respective predetermined maximum inflated diameters, and respective longitudinal positions on said catheter shaft, each said axis of each said balloon being distanced from the other said balloon axes, and provided that when one said balloon is positioned at the same longitudinal position as any other said balloon, the lengths of said balloons are different.
An angioplasty catheter, comprising:
- a hollow metal tube having a proximal end and a distal end with at least two lumens extending through said tube;
- and
- a first angioplasty balloon and a second angioplasty balloon attached to said tube near said distal end of said tube, each said balloon being in fluid communication with a respective said lumen, said balloons being eccentric with respect to said tube, said first and second balloons having respective first and second lengths and respective first and second inflated diameters, said first length being different than said second length and said first inflated diameter being different than said second inflated diameter.
