Abstract
A medical catheter comprising a catheter shaft defining an inflation lumen and a guidewire shaft defining a guidewire lumen. The guidewire shaft is coaxial with the catheter shaft and runs longitudinally through the catheter shaft extending distally beyond the distal end of the catheter shaft. The catheter has an inflatable balloon having a proximal tail and a distal tail. The proximal tail is mounted at the distal end of the catheter shaft, the distal tail is mounted on the guidewire shaft. The balloon is in fluid communication with the inflation lumen. A distal stopper is sealingly affixed between the outer diameter of the guidewire shaft and the inner diameter of the distal tail. A proximal stopper is sealingly affixed between the outer diameter of the catheter shaft and the inner diameter of the proximal tail. The distal and proximal stopper are annular in shape and are in length shorter than the balloon tail and are of uniform circumferential thickness. An adhesive seals a portion of the tails to the catheter shaft.
