Abstract
Abstract The balloon dilatation catheter has a first lumen extending along the entire length of a shaft, which lumen is connected to a pump and, at the distal end of the catheter, to the inside of the balloon. Through this lumen there also passes a support wire connected firmly to the catheter. The shaft has an additional lumen which opens outwards via an opening behind the proximal end of the balloon. A controllable guide wire can be introduced into this lumen via an attachment piece. Similarly, a measuring apparatus or an apparatus for introducing a contrast medium or drug can be connected to this additional lumen. The catheter is particularly suitable for treating strictures in an arterial ramification.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
221 words
A method for dilating a stenosis in each of a pair of branch coronary arteries comprising: introducing into a first branch coronary artery a steerable balloon dilatation catheter having a shaft with a distal end and a proximal end and a first lumen extending through the shaft, a balloon with a distal end and a proximal end arranged at the distal end of the shaft, the first lumen being in communication with the balloon, a first guidewire extending through and fixed within the first lumen and a second lumen extending through a portion of the shaft and having an opening outwards of the shaft before the proximal end of the balloon, the second lumen being adapted to have a second guidewire pass therethrough; advancing the second guidewire through the second lumen and through the opening into a second branch coronary artery; inflating the balloon to effect a dilatation of a stenosis in the first branch coronary artery; deflating the balloon; withdrawing the steerable balloon dilatation catheter from the first branch coronary artery while maintaining the second guidewire in the second branch coronary artery; advancing a balloon dilatation catheter over the second guidewire into the second branch coronary artery; and inflating the balloon of the balloon dilatation catheter to effect a dilatation of a second stenosis in the second branch coronary artery.
