US 6596020 B2Abstract
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.
What is claimed is: 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.
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.
The present application is a divisional of pending U.S. Application No. 09/325,996, filed on Jun. 4, 1999, which claims the benefit under 35 USC 119 of now expired U.S. Application No. 60/088,301, filed Jun. 5, 1998, and which also is a continuation-in-part of expired PCT Application No. US99/00835, filed Jan. 13, 1999, which is continuation-in-part of U.S. Application No. 09/007,265, filed Jan. 14, 1998, which issued on Apr. 3, 2001 as U.S. Pat. No. 6,210,429 and which is a continuation-in-part of U.S. Application No. 08/744,002 filed Nov. 4, 1996, now abandoned. U.S Application No. 09/325,996, of which the present application is a divisional, is also a continuation-in-part of U.S. Application No. 08/935,383, now abandoned, which is a divisional of U.S. Application No. 08/744,002, now abandoned, all of which are incorporated herein by reference in their entireties.
FIG. 1. is an illustration of a dual lumen catheter having a side sheath slidably received within a second lumen of the dual lumen catheter.
FIG. 2. is an illustration of a dual lumen catheter having a second catheter slidably received within a second lumen of the dual lumen catheter, with balloons positioned on the distal ends of both of the dual lumen catheter and the second catheter.
FIG. 3 is an illustration of a placement of first guidewire within a primary vessel.
FIG. 4 is an illustration of the dual lumen catheter and side sheath advanced over the first guidewire to a position where the side opening in the primary stent is adjacent with the mouth of the branch vessel.
FIG. 5 is an illustration of the second guidewire as it is advanced out of the distal end of the side sheath, through the side opening in the primary stent and into the branch vessel.
FIG. 6 is an illustration of a branch stent of advanced over the second guidewire and through the side opening in the primary stent and into the branch vessel by a second catheter received within the second lumen of the dual lumen catheter.
FIG. 7 is an illustration of the deployment of the branch stent by a second balloon disposed over the second guidewire.
FIG. 8 is an illustration of the fully deployed primary and branch stents with the guidewires and dual lumen catheter removed.
FIG. 9 shows an embodiment of the present invention with radially expandable portions around the side opening on the primary stent.
FIG. 6 is similar to FIG. 5, but side sheath 14 has been removed and a second catheter 20 has been advanced over guidewire 31 with a branch stent 40 disposed at distal end 26 of catheter 20. As shown in FIG. 6, distal end 26 of catheter 20 can be advanced over guidewire 31 such that stent 40 is advanced through side hole 27 in stent 25 and is positioned in branch vessel B.
