Abstract

A method of aligning a side opening in a primary stent in registry with the ostium of a branch vessel includes 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. A second guidewire is advanced out of the stent through the side opening and into the branch vessel.

Claims

1. 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.

2. The method of claim 1, further comprising:

deploying the stent within the primary vessel by inflating a balloon disposed on the catheter.

3. The method of claim 1, further comprising viewing the position of the distal end of the side sheath under fluoroscopy.

4. The method of claim 2, further comprising:

inflating a second balloon disposed on the side sheath.

5. The method of claim 2, further comprising retracting the catheter and the side sheath, and advancing a branch stent over the second guidewire, through the side opening the stent into the branch vessel.
