<p>A bifurcated catheter includes a first catheter branch having a first distal portion and a second catheter branch having a second distal portion. The first and second distal portions are linked together by a pocket disposed on the first distal portion of the first branch catheter. The pocket includes a proximal opening, a distal opening, and a slit. The pocket is sized and shaped to receive the second distal portion. When the second distal portion is inserted into the pocket, the first and second catheter branches are linked together for delivery to the bifurcated region over a first guidewire. Upon delivery to the bifurcated region, a guidewire is advanced through the second catheter branch and into a branch vessel. As first and second catheter branches are advanced over the first and second guidewires, respectively, a force pulling the catheter branches apart pulls the second distal portion through the slit of the pocket, thereby releasing the first and second catheter branches from each other.</p> |
