Abstract
Described here are devices, systems, and methods for cannulating a vessel. Generally, the method may comprise advancing a stent into a first vessel and deploying the stent in the first vessel to hold open one or more valves. This may permit retrograde blood flow through the blood vessel in peripheral vasculature and aid in cannulation of the blood vessel.
