Abstract

A balloon catheter, preferably of the float-advancement type, defines a balloon carried adjacent the catheter distal end and a first catheter lumen communicating between the balloon at a proximal catheter location. By this invention, second and third, separate catheter lumens extend between proximal and distal catheter locations and are open at each end. The second and third catheter lumens are each proportioned to receive a catheter advancement guidewire to permit installation of a pair of the guidewires at desired body locations. Preferably, the second and third lumens define distal open ends which are longitudinally spaced from each other.

Claims

1. In a balloon catheter which defines a catheter shaft, and a balloon carried adjacent the catheter shaft distal end;

a first catheter lumen communicating through the shaft between the balloon and a proximal catheter location, the improvement comprising, in combination;

second and third separate catheter lumens extending through the shaft between proximal and distal catheter locations and open at each end, said second and third catheter lumens each carrying a catheter advancement guidewire, each guidewire being free of attachment to said catheter, to permit installation of said guidewires at desired body locations.

2. The balloon catheter of claim 1 which is proportioned and adapted to be of the float-advancement type.

3. The balloon catheter of claim 1 in which the second and third lumens define distal open ends which are longitudinally spaced from each other.

4. The balloon catheter of claim 3 in which the diameter of the catheter portion between the second and third lumen distal open ends is less than the diameter of the catheter portion which is proximal to both of the second and third lumen distal open ends.

5. In a balloon catheter of the float-advancement type which defines a catheter shaft, and a balloon carried adjacent the catheter shaft distal end;

a first catheter lumen communicating through the shaft between the balloon and a proximal catheter location, the improvement comprising, in combination;

second and third separate catheter lumens extending through the shaft between proximal and distal catheter locations and open at each end, said second and third catheter lumens each carrying a catheter advancement guidewire, each guidewire being free of attachment to said catheter, to permit installation of said guidewires at desired body locations, in which the second and third lumens define distal open ends which are longitudinally spaced from each other.

6. The balloon catheter of claim 5 in which the diameter of the catheter portion between the second and third lumen distal open ends is less than the diameter of the catheter portion which is proximal to both of the second and third lumen distal open ends.
