Method and apparatus for selective drug infusion via an intra-aortic flow diverter delivery catheter

摘要

A local renal delivery system includes a flow isolation assembly and a local injection assembly. The flow isolation assembly in one mode is adapted to isolate only a partial flow region along the outer circumference along the aorta wall such that fluids inject there are maintained to flow substantially into the renal arteries. Various types of flow isolation assemblies and local injection assemblies are described.
