Abstract:
A method of delivering a stent having a side opening configured to be aligned with the ostium of a branch vessel, comprising:advancing a first guidewire through a primary vessel such that a distal end of the first guidewire extends past an intersection of the primary vessel and the branch vessel; advancing a catheter over the first guidewire to the intersection of the primary vessel and the branch vessel, the catheter comprising a catheter body having a proximal end, a distal end, a first guidewire lumen extending between the proximal end and the distal end through which the first guidewire passes, and a stent having a side opening disposed over the catheter, and a side sheath coupled to the catheter body and the stent, the side sheath having a second guidewire lumen; and thereafter advancing a second guidewire through the second guidewire lumen of the side sheath such that the second guidewire passes through the side opening in the stent and into the branch vessel.
