Abstract
An angioplasty guide catheter adapted for use within a cardiovascular system and cooperable with a left main coronary artery. The guide catheter has a distal end portion such that with a distal tip of the distal end portion coaxially intubated within an ostium of the left main coronary artery fully disposed within the cardiovascular system, a portion of the distal end portion rests against and is substantially contiguous with a wall of the ascending aorta. A distal end of the resting portion is substantially directly opposite the ostium of the left main coronary artery and a portion of the distal end portion defines a generally rectilinear axis of support extending from the distal end of the resting portion across the ascending aorta to the ostium of the left main coronary artery.
Claims6
An assembly for guiding the path of a therapeutic catheter, comprising:
- an elongate tubular member including a proximal shaft portion, a profiled portion, and a substantially straight tip portion;
- the profiled portion comprising, in order from the proximal 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;
- the first bend, the first substantially straight leg, the second bend, the second substantially straight leg, and the third bend being disposed within a chamber of an aorta;
- a distal end of the tip portion being disposed within an ostium defined by the aorta;
- the first substantially straight leg seating against a wall of the aorta opposite the ostium of the coronary artery;
- and
- the elongate tubular member defining a lumen extending from a distal end of the elongate tubular member to a proximal end of the elongate tubular member, wherein the lumen is constructed and arranged to receive the therapeutic catheter.
A femoral approach angioplasty guide catheter adapted for selective catheterization of a coronary artery within a cardiovascular system including an aorta, comprising:
- an elongate tubular member having a shaft, a profiled portion, and a substantially straight tip portion;
- the catheter profiled portion comprising, in order from the proximal 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;
- wherein substantially the entire length of the first substantially straight leg seats against a wall of the aorta opposite an ostium of the coronary artery when a distal end of the tip portion is positioned within the ostium of the coronary artery.
An assembly for guiding the path of a therapeutic catheter through the aorta to an ostium of the coronary artery, comprising:
- an elongate tubular member including a proximal shaft portion, a profiled portion, and a substantially straight tip portion;
- means for engaging an ostium of the coronary artery;
- means for seating against a wall of the aorta including a first bend, a first substantially straight leg, a second bend, a second substantially straight leg, and a third bend;
- and
- the elongate tubular member defining a lumen extending from a distal end of the elongate tubular member to a proximal end of the elongate tubular member, wherein the lumen is adapted and configured to receive the therapeutic catheter.
A femerol approach angioplasty guide catheter adapted for selective catheterization of a coronary artery within a cardiovascular system including an aorta, comprising:
- an elongate tubular member having a shaft, a profiled portion, and a substantially straight tip portion;
- the catheter profiled portion comprising, in order from the proximal 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;
- wherein the first substantially straight leg comprises means for seating against a wall of the aorta opposite an ostium of the coronary artery when a distal end of the tip portion is positioned within the ostium of the coronary artery.
A method for guiding the path of a therapeutic catheter, comprising:
- providing an elongate tubular member including a proximal shaft portion, a profiled portion, and a substantially straight tip portion;
- wherein the profiled portion comprises, in order from the proximal 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;
- wherein the elongate tubular member defines a lumen extending from a distal end of the elongate tubular member to a proximal end of the elongate tubular member, wherein the lumen is adapted and configured to receive the therapeutic catheter therein;
- disposing a distal end of the tip portion within an ostium the coronary artery;
- and
- seating the first substantially straight leg against a wall of the aorta opposite the ostium of the coronary artery.
