Abstract

The invention generally relates to catheter systems and methods for guided formation of vascular access sites (such as fistulas and grafts). According to certain aspects, a catheter system for forming a vascular access site include an elongate body comprising a distal end and configured to be inserted into a first vessel. The elongate body includes an exit port along its side that is proximal to the distal end. An imaging assembly is associated with the elongate body and configured to generate image data of the first vessel and a second vessel positioned next to the first vessel. For vascular access formation, a penetrating member of the catheter system extends out of the exit port and through a wall of the first vessel and a wall of the second vessel.
