A guide catheter for insertion into the cardiovascular system having a straight portion and an improved distal end portion for more precise and easier positioning in a left coronary artery. The improved distal portion includes a secondary curved portion, followed distally by a primary curved portion, terminating with a distal tip portion. The primary and secondary curved portions are constructed such that the primary and secondary curved portions have an approximately equal curvature radii when the distal tip portion is positioned in the ostium of the left coronary artery, thereby forming a constant radius curve.

Un cathéter de guidage introduit dans le système cardiovasculaire possède une partie droite et une partie extrême distale améliorée permettant d'effectuer un positionnement plus précis et plus simple dans l'arthère coronaire gauche. La partie distale améliorée comprend une partie incurvée secondaire se poursuivant à son extrémité distale par une partie incurvée principale laquelle se termine par une partie pointe distale. Les parties incurvées principale et secondaire sont construites de sorte qu'elles ont des rayons de courbure sensiblement égaux lorsque la partie pointe distale est positionnée dans l'orifice de l'arthère coronaire gauche, formant ainsi une courbe à rayon constant.
