Abstract
Renal infusion systems include an infusion catheter having a bifurcated distal end with a first branch and second branch, the branches being biased to deploy laterally when unconstrained. Systems also include a delivery sheath having a lumen which receives the infusion catheter and constrains the first branch and second branch. A distal opening of the delivery sheath is formed asymmetrically to allow one of the first and second branches to open laterally while the other of the branches remains constrained. Methods of using renal infusion systems are also provided.
