摘要
A torqueable, three-dimensionally preformed guide or diagnostic catheter to selectively engage the ostium (32) of a right coronary artery (36) in a human includes: a torque-transmitting proximal shaft that receives manipulation by a user outside a human body in which the catheter is used; and a distal shaft that is responsive to torque transmitted by the proximal shaft. The distal shaft (8) also includes a preformed support section having at least a segment that abuts a posterior interior surface of the ascending aorta of the human body. The distal shaft (8) also includes a preformed ostium entry section extending from the support section. In one implementation, the ostium entry section transitions from the support segment abutting the aortic wall to a distal tip (22) end by way of at least two angles, which provide smoother transition than a single sharp angle.
