Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
A method for advancing a catheter through the aorta and into a coronary ostium, the aorta having an arch and an inner wall opposite the ostium, comprising the steps of: providing a catheter including an elongate catheter body having a proximal end and a distal end and having a central lumen from the proximal end to the distal end adapted to slidably receive a therapeutic catheter, the catheter body including a tip at the distal end of the catheter body adapted to removably lodge in the coronary artery ostium; advancing the catheter body distal end through the aortic arch; and engaging the aorta inner wall with a portion of the catheter body such that when the distal end of the catheter is positioned in the ostium, the catheter body engages the opposite wall of the aorta along a line having a length of about 1.5 cm or greater.
Claim 2
Independent Claim
148 words
A method for advancing a catheter through the aorta and into a coronary ostium, the aorta having an arch and an inner wall opposite the ostium, comprising the steps of: providing a catheter including an elongate catheter body having a proximal end and a distal end and having a central lumen from the proximal end to the distal end adapted to slidably receive a therapeutic catheter, the catheter body including a tip at the distal end of the catheter body adapted to removably lodge in the coronary artery ostium; advancing the catheter body distal end through the aortic arch; and engaging the aorta inner wall with a portion of the catheter body such that when the distal end of the catheter is positioned in the ostium, the catheter body engages the opposite wall of the aorta along a line having a length of about 1.5 cm or greater.
Claim 3
Dependent Claim
15 words
A method in accordance with claim 1, wherein the ostium is the left coronary ostium.
Claim 4
Dependent Claim
32 words
A method in accordance with claim 2, further comprising the step: further advancing the catheter distal end into the coronary artery ostium while engaging the aorta inner wall with the body portion.
Claim 5
Independent Claim
142 words
A method for advancing a catheter through an aorta and into a branch artery, the aorta having an arch and an inner wall opposite the branch artery, comprising the steps of: providing a catheter including a tubular member having a shaft, an integral profiled portion, and an integral, substantially straight tip portion, the tip portion being adapted to axially engage the branch artery; wherein the catheter profiled portion comprises, in order from the shaft portion to the tip portion, a first bend, a first substantially straight leg, a second bend, a second substantially straight leg, and a third bend; advancing the catheter tip portion through the aorta; and engaging the branch artery with the tip portion, such that when the tip portion is engaged with the branch artery, the profiled portion engages the aorta wall opposite the branch artery along a line.
Claim 6
Independent Claim
142 words
A method for advancing a catheter through an aorta and into a branch artery, the aorta having an arch and an inner wall opposite the branch artery, comprising the steps of: providing a catheter including a tubular member having a shaft, an integral profiled portion, and an integral, substantially straight tip portion, the tip portion being adapted to axially engage the branch artery; wherein the catheter profiled portion comprises, in order from the shaft portion to the tip portion, a first bend, a first substantially straight leg, a second bend, a second substantially straight leg, and a third bend; advancing the catheter tip portion through the aorta; and engaging the branch artery with the tip portion, such that when the tip portion is engaged with the branch artery, the profiled portion engages the aorta wall opposite the branch artery along a line.
Claim 7
Dependent Claim
31 words
A method in accordance with claim 4, further comprising the step: further advancing the catheter tip portion into the branch artery while engaging the aorta inner wall with the profiled portion.
