1. A delivery system, comprising:
- a catheter having a tubular shell with a proximal end and a distal end;
a first lumen disposed in the catheter, the first lumen having a distal opening located at the distal end of the catheter and a proximal opening located on the tubular shell proximal to the distal end of the tubular shell;
a second lumen disposed in the catheter, the second lumen having a distal opening located on the tubular shell a predetermined distance from the distal end of the catheter and a proximal opening located on the tubular shell proximal to the second lumen distal opening; and
a device positioned near the distal end of the catheter, wherein the predetermined distance is greater than a length of the device such that the second lumen distal opening is located proximally with respect to a proximal end of the device.

Abstract
A delivery system for delivering a stent to a bifurcation in a vessel. The delivery system includes two guidewire lumens for directed the stent through the anatomy to the bifurcation. A main branch guidewire lumen has entry and exit ports that are positioned in order to limit how far the delivery system will be allowed into a side branch vessel. The orientation of the main branch guidewire lumen causes the delivery system to bind on the main branch guidewire as the system is positioned in the side branch. The location of the main branch guidewire lumen openings will physically limit the distance into the side branch that the stent will be placed.

15. A method of delivering a device to a location in a vessel system of a patient, the device positioned on a catheter having a tubular shell with a proximal end and a distal end, a first lumen disposed in the catheter, the first lumen having a distal opening located at the distal end of the catheter, a second lumen disposed in the catheter, the second lumen having a distal opening located on the tubular shell a predetermined distance from the distal end of the catheter, wherein the predetermined distance is greater than a length of the device such that the second lumen distal opening is located proximally with respect to a proximal end of the mounted device and no portion of the second lumen passes through a lumen of the mounted device, the method comprising:
-
inserting a first guidewire into a first vessel of the vessel system;
inserting a second guidewire into a second vessel of the vessel system;
inserting a proximal end of the first guidewire through the first lumen distal opening and into the first lumen;
inserting the second guidewire into the second lumen distal opening and into the second lumen;
inserting the catheter into the patient and advancing the catheter along the first guidewire into the first vessel;
determining whether the second guidewire is binding on the catheter; and
if it is determined that the second guidewire is binding on the catheter, terminating advancement of the catheter into the first vessel. - View Dependent Claims (16, 17, 18, 19, 20, 21)
