Abstract:
A catheter for a right coronary artery, comprising:a proximal shaft having a proximal end to receive manipulation by a user outside a human body in which the catheter is used; and a distal shaft extending from the proximal shaft opposite the proximal end of the proximal shaft, the distal shaft including: a preformed support section to abut a posterior interior surface of the ascending aorta of the human body, wherein the support section includes: a transition segment connected to the proximal shaft at a first bend initially forming an included angle of between 135Â° and 175Â°, wherein the transition segment is initially substantially linear; and an abutment segment connected to the transition segment at a second bend initially forming an included angle of between 135Â° and 175Â°, wherein the abutment segment is initially substantially linear; and a preformed ostium entry section extending from the preformed support section, wherein the preformed ostium entry section includes: a first segment connected to the abutment segment at a third bend initially forming an included angle of between 80Â° and 160Â°, wherein the first segment is initially substantially linear; a second segment connected to the first segment at a fourth bend initially forming an included angle of between 100Â° and 170Â°, wherein the second segment is initially substantially linear; and wherein the first and second segments are initially offset from an imaginary plane defined by the transition and abutment segments of the preformed support section.
