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.

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： 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.

摘要： A dual lumen introducer sheath provides access to at least one renal artery and at least one peripheral blood vessel of a patient. The introducer sheath includes a proximal hub comprising first and second ports, a first lumen, and a second lumen. The first lumen extends from the first port to a first distal aperture and has sufficient length such that when the first port is positioned outside the patient the first distal aperture is positionable in the abdominal aorta at or near origins of the patient's renal arteries. The second lumen extends from the second port to a second distal aperture, has a shorter length than the length of the first lumen, and is configured to allow passage of a catheter device through the second lumen and into or through an iliac artery contralateral to an insertion point of the introducer sheath into the patient.

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： Two renal delivery members have two distal ports that are adapted to be positioned within two renal arteries via their corresponding renal ostia at unique locations along an abdominal aortic wall. A proximal coupler assembly is outside the body and is coupled to deliver material to the two distal ports for bi-lateral renal therapy. One or both of the delivery members may be self-cannulating into the corresponding renal ostium, or may be controllably steered into the respective ostium. Non-occlusive anchors may be coupled with one or both of the delivery members at anchoring positions in the renal artery or abdominal aorta to secure the renal delivery member within the renal artery. Renal-active fluid agents are coupled to the bi-lateral delivery system. Another renal therapy system cannulates a renal vein from the vena cava and controls a retrograde delivery of agents to the respective kidney.

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.
