Systems and methods for performing bi-lateral interventions or diagnosis in branched body lumens
First Claim
1. A medical device assembly for performing an interventional procedure in at least one renal vessel extending from an aorta in a body of a patient, comprising:
- a bifurcated catheter assembly having a proximal end portion and a distal end portion with first and second branches;
wherein the first and second branches each have a pre-formed shape for substantially self-cannulating bi-laterally within first and second renal vessels that extend from the aorta;
wherein the first branch is adapted to be positioned within the first renal vessel and is adapted to position, at least in part, an interventional device within the first renal vessel.

Abstract
Bifurcated delivery assemblies provide bilateral access to first and second branch lumens extending from a main body space or lumen in a patient. One or more interventional devices are combined with the delivery assemblies for delivery s into one or both of the branch lumens. Bilateral renal stenting or embolic protection procedures are performed using the combination delivery/interventional device assemblies. Fluids may also be injected or aspirated from the assemblies. A bifurcated catheter has a first fluid port located on one bifurcation branch, a second fluid port located on a second branch of the bifurcation, and a third fluid port positioned so as to be located within a vena cava when the first and second ports are positioned bilaterally within first and second renal veins.
