Abstract
A system and method for navigating coronary vasculature involves use of a guide catheter system which includes a guide catheter, a navigator catheter longitudinally displaceable within the guide catheter, and a deflection arrangement provided at a distal end of the navigator catheter. The guide catheter is advanced to at least a patient'"'"'s coronary sinus ostium, and the navigator catheter is extended from the guide catheter to a location proximate or within an angled vein distal to the coronary sinus ostium. Using the deflection arrangement, a guide wire passing through the navigation catheter is directed into the angled vein. A lead having an open lumen is advanced over the guide wire to direct the lead to an implant site within the angled vein.

2. A method of delivering an implantable lead to an implantation location in a coronary vein of a patient, the method comprising:
-
inserting a guide catheter system into the patient'"'"'s vasculature, the guide catheter system including a guide catheter having a lumen and a distal end, and a navigator catheter disposed within the lumen of the guide catheter, the navigator catheter including a distal end having a pre-shaped bend; advancing the guide catheter into the coronary sinus; extending the distal end of the navigator catheter out the distal end of the guide catheter to a location proximate or within an angled vein distal to the coronary sinus; and advancing a lead through the guide catheter or the navigator catheter to direct the lead to an implant site within the angled vein. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 14, 15)

10. A method of delivering an implantable lead to an implantation location in a coronary vein of a patient, the method comprising:
-
inserting a guide catheter into the patient'"'"'s vasculature system, the guide catheter system including a guide catheter and a navigator catheter longitudinally displaceable within the guide catheter, the navigator catheter including a pre-formed distal end having a bend; advancing the guide catheter to a patient'"'"'s coronary sinus ostium; extending the navigator catheter from the guide catheter to a location proximate an angled vein distal to the coronary sinus ostium; seating the navigator catheter within the angled vein; passing the guide catheter over the navigator catheter to advance the guide catheter into the angled vein; retracting the navigator catheter from the guide catheter; and advancing a lead through the guide catheter to an implant site within the angled vein. - View Dependent Claims (11, 12, 13)
