Abstract
An introducer system delivers therapy locally to a renal system in a patient. A proximal coupler assembly is coupled to an introducer sheath that delivers multiple devices simultaneously into a location within an abdominal aorta associated with first and second renal artery ostia. The coupler assembly has a network of branch lumens arranged to allow for smooth slideable engagement of multiple coupled devices without substantial interference therebetween. A first branch lumen typically introduces a percutaneous translumenal interventional device such as an angiography or guiding catheter into the introducer sheath and is substantially aligned with a longitudinal axis of the sheath. One or more other branch lumen are off-axis from the longitudinal axis by about 30 degrees or less and introduce components of a bilateral renal delivery assembly into the introducer sheath in conjunction with the other device. Novel insertion devices are provided to coordinate the coupling of the multiple devices.
