Abstract:
A femoral approach right coronary artery catheter configured to be directed to an ostium of a patient's right coronary artery through an aortic arch and ascending aorta, comprising a flexible tubular body stock having a distal end and a nonlinear stem extending from the distal end of the body stock, the stem including a distal end, a primary curved section having one or more free state radii and a free state arc length and positioned between the distal ends of the stem and body stock, and a secondary curved section having one or more free state radii and a free state arc length and positioned between the primary curved section and the distal end of the body stock and extending in a direction generally opposite the direction of the primary curved section, and wherein the radii and lengths of the stem including the primary and secondary curved sections are adapted to cause a portion of the stem between the secondary curved section and the distal end of the body stock to engage a continuous length of the upper wall of the aortic arch, to cause the secondary curved section to direct the stem generally downwardly and across the ascending aorta toward a contralateral wall opposite the ostium of the right coronary artery, and to cause the primary curved section to engage the contralateral wall at a location adjacent to the ostium of the left coronary artery and to direct an end section of the stem across the ascending aorta toward the ostium of the right coronary artery, when the catheter is positioned within the patient with the distal end of the stem engaged with the ostium of the right coronary artery.
