Abstract:
1. A method of accessing a renal artery of a patient comprising the steps of: providing a deflectable guide catheter characterized by a distal end and a proximal end and a wall thickness, said deflectable guide catheter comprising a main body section and a deflectable segment disposed at the distal end thereof, said deflectable segment having a total wall thickness of about 1 French and comprising a deflectable member configured to provide a bend arc of about 90° to 135° and a bend radius of about 1 inch (2.5 cm), and a pullwire operably connected to the deflectable segment from the proximal end of the deflectable guide catheter; inserting the deflectable guide catheter percutaneously, through an access point in a vasculature of the patient, and navigating the deflectable guide catheter through the vasculature to locate the deflectable segment into proximity with a renal artery of the patient, and operating the deflectable segment and rotating the guide catheter as necessary to manipulate the deflecting segment into the renal artery; the deflectable segment consists of a PTFE liner, a coil disposed over the PTFE liner, the deflectable member, an outer jacket and the pullwire.
