Abstract
(EN)
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.

L'invention concerne des dispositifs de perfusion rénale qui comprennent un cathéter de perfusion dont l'extrémité distale présente une bifurcation avec une première branche et une deuxième branche, les branches étant sollicitées pour se déployer latéralement lorsqu'elles ne sont pas sous contrainte. Les dispositifs comprennent aussi une gaine de déversement qui présente une lumière qui reçoit le cathéter de perfusion et contraint la première branche et la deuxième branche. Une ouverture distale de la gaine de déversement est formée en position asymétrique pour permettre à la première branche et/ou la deuxième branche de s'ouvrir latéralement pendant que l'autre branche reste sous contrainte. L'invention concerne également des procédés d'utilisation des dispositifs de perfusion rénale.
