Abstract

The invention relates to a balloon catheter comprising a catheter tube having a first lumen and a second lumen, each lumen having a proximal end and a distal end, an inflatable balloon having a proximal end and a distal end, and a guide wire receivable in the second lumen. The distal end of the first lumen opens into the balloon. The distal end of the second lumen is open and positioned proximally of the proximal end of the balloon.

Claims

1. A balloon catheter comprising a catheter tube having a first lumen and a second lumen, each lumen having a proximal end and a distal end, an inflatable balloon having a proximal end and a distal end, and a guide wire receivable in the second lumen, with the distal end of the first lumen opening into the balloon, characterized in that the distal end of the second lumen is open and positioned proximally of the proximal end of the balloon.

2. A balloon catheter according to claim 1, wherein the catheter includes a tip, and the distal end of the balloon is connected to the tip.

3. A balloon catheter according to claim 2, wherein the guide wire has a distal end, and the tip comprises a lumen for receiving the distal end of the guide wire.

4. A balloon catheter according to claim 1, wherein the catheter tube is provided with an opening which is in communication with the second lumen, which opening is positioned proximally of the distal end of the second lumen.

5. A balloon catheter according to claim 1, which further comprises a stiffening wire which is received in the first lumen.

6. A catheter having a proximal end and a distal end, comprising an inflatable balloon at the distal end of the catheter and a guide wire at least at the distal end of the catheter, characterized in that the guide wire is positioned free of and outside of the balloon at the distal end of the catheter in an inflated condition of the balloon.
