Abstract
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 Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
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.
Claim 2
Independent Claim
165 words
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.
Claim 3
Dependent Claim
23 words
The method of claim 1 , further comprising: deploying the stent within the primary vessel by inflating a balloon disposed on the catheter.
Claim 4
Dependent Claim
21 words
The method of claim 1 , further comprising viewing the position of the distal end of the side sheath under fluoroscopy.
Claim 5
Dependent Claim
17 words
The method of claim 2 , further comprising: inflating a second balloon disposed on the side sheath.
Claim 6
Dependent Claim
34 words
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.
