    摘要： A system for delivering a renal treatment and a peripheral treatment includes a renal catheter, a peripheral catheter, and an introducer sheath having first and second lumens. The first lumen is configured to receive the renal catheter and is sized to extend from a patient insertion site to a femoral or iliac artery location near or distal to a patient aortic branch. The second lumen is configured to receive the peripheral catheter and is sized to extend from the patient insertion site to an opposite femoral or iliac artery location near or distal to the patient aortic branch. A method of delivering a renal treatment and a peripheral treatment includes positioning an introducer sheath in an iliac artery, advancing a renal catheter and a peripheral catheter through the introducer sheath, where the renal catheter is separated from the peripheral catheter within the introducer sheath by a flap.

    摘要： A renal flow system injects a volume of fluid agent into a location within an abdominal aorta in a manner that flows bi-laterally into each of two renal arteries via their respectively spaced ostia along the abdominal aorta wall. A local injection assembly includes two injection members, each having an injection port that couples to a source of fluid agent externally of the patient. The injection ports may be positioned with an outer region of blood flow along the abdominal aorta wall perfusing the two renal arteries. A flow isolation assembly may isolate flow of the injected agent within the outer region and into the renals. The injection members are delivered to the location in a first radially collapsed condition, and bifurcate across the aorta to inject into the spaced renal ostia. A delivery catheter for upstream interventions is used as a chassis to deliver a bilateral local renal injection assembly to the location within the abdominal aorta.

    摘要： 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.

    摘要： A system and method is provided that is adapted to allow for rapid cannulation of a guidewire into a branch lumen extending from a main lumen in a body of a patient, and in particular into two renal arteries extending from an abdominal aorta wall. A dual lumen catheter shaft delivers first and second pre-shaped guidewires to the location of the renal arteries in the aorta, such that the first and second pre-shaped guidewires self-cannulate within the renal arteries. Additional guidewires and/or interventional devices may be incorporated into the system and method for use with the catheter shaft, or over the two pre-shaped guidewires, to meet a particular need for a particular patient or intended procedure.

    摘要： An apparatus and method particularly useful in treatments and therapies directed at the kidneys such as the prevention of radiocontrast nephropathy (RCN) arising from diagnostic procedures using iodinated contrast materials. A series of treatment schemes are provided based upon local therapeutic agent delivery to the kidneys that can be used as a prophylactic treatment for patients undergoing interventional procedures that have been identified as being at an elevated risk for developing RCN as well as for low risk patients. The methods may include pre-exposure and post contrast exposure treatments alone or in combination with the local delivery of therapeutic agents to the kidneys. Among the agents identified for such treatments are normal saline and the vasodilators papaverine and fenoldopam mesylate and appropriate dosing is provided.
