Claim Text:
1. A guiding catheter system, comprising: a guiding catheter comprising a proximal end, a distal end, a primary lumen and a secondary lumen; and a stabilizing wire comprising an elongate part and a first fortified end disposed on a first end of the elongate part, wherein the first fortified end forms a first end of the stabilizing wire and is more rigid than the elongate part; wherein the secondary lumen extends the entire length of the guiding catheter and has a distal blind end at a distal edge of the distal end of the guiding catheter; and wherein the stabilizing wire is configured to be inserted into the secondary lumen to the blind end while the guiding catheter is at an ostium of a vessel of a patient such that the first fortified end of the stabilizing wire increases the rigidity of at least a portion of the guiding catheter thereby preventing the guiding catheter from disengaging from the ostium of the vessel; and wherein the first fortified end of the stabilizing wire is configured to change the shape of at least a portion of the guiding catheter when the first fortified end of the stabilizing wire is inserted such that the guiding catheter rests on a wall of the aorta opposite an ostium of a coronary artery.
