Abstract
Described herein are devices and methods for vascular access via the tributaries. A single lumen catheter, with a bidirectional valve at the tip is disclosed. Flow is out the longitudinal tip of the catheter and not the sides. The two-way valve will act passively but has low opening and closing pressures. A method utilizing endo-to-side port placement of said catheter in vasculature is disclosed. Anastomosis methods are described using said catheter.
