Patent ID: 8562573

Claim:
A guiding catheter system for the insertion of a catheter into a renal artery, the system consisting of: a guiding catheter having an elongated hollow tube that has proximal and distal ends and a distal section, the distal section having a curved section and a straight section extending from the distal end of the curved section, the curved section and the straight section being shaped so as to facilitate introduction and retention of the guiding catheter's distal section into and through the ostium of a renal artery for any angle of the renal artery relative to the aorta that lies between 30 and 90 degrees; a dilator inserted into the guiding catheter's hollow tube with a curved distal section of the dilator being placed at 180 degrees opposite the curved distal section of the hollow tube of the guiding catheter so that the assembly of the guiding catheter and the dilator forms an essentially straight distal section; the guiding catheter having a side arm tube located near the guiding catheter's proximal end with a multi-way stopcock fixedly attached onto the proximal end of the side arm tube; and a backflow adapter fitted to the hollow tube at the proximal end of the guiding catheter, a side arm tube joined to a threaded base of the backflow adapter, the side arm tube extending outward from the threaded base in a direction that is substantially co-planar with the plane of the curved distal section of the hollow tube of the guiding catheter and the side arm tube extending in the same direction outward from the hollow tube of the guiding catheter as the curved distal section of the guiding catheter.
