  • Patent number: 11305095
    Abstract: The present disclosure relates to devices and methods for accessing a targeted vessel, such as a coronary artery, near the aortic root. A catheter device includes a proximal section, an intermediate section, and a distal section. The intermediate section includes a more proximal section (a proximal-intermediate section) and a more distal section (a distal-intermediate section). The proximal-intermediate section is microfabricated to enable preferred bending along a single plane. The distal-intermediate section is more rigid than the proximal-intermediate section and the distal section. In use, the proximal-intermediate section abuts against the aortic wall and bends to allow the distal-intermediate section to extend across the aortic root toward a targeted vessel on the opposite side of the aorta.
