Abstract:
1. A system for treating a vessel bifurcation comprising: a bifurcated catheter, the catheter being divided into a first branch and a second branch at a distal section of the catheter, each branch comprising a catheter shaft and a guidewire port, the catheter shaft of each branch having a proximal end and a distal end, at least a portion of the catheter shaft defining a guidewire lumen and the guidewire port in fluid communication, the guidewire port defining an aperture extending through a sidewall of the catheter shaft, each branch having an exchange region that extends from the distal end of the catheter shaft to the guidewire port of the catheter shaft, the exchange region of the first branch of the catheter having a first stiffness and the exchange region of the second branch of the catheter having a second stiffness, the first stiffness being different from the second stiffness.
