Patent number: 9956377Abstract: A renal flow system injects a volume of fluid agent into a location within an abdominal aorta in a manner that flows bilaterally 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.Type: GrantFiled: September 23, 2013Date of Patent: May 1, 2018Inventors: Jeffrey M. Elkins, Aurelio Valencia, Samir R. Patel, Ricardo Aboytes, Harry B. Goodson, Craig A. Ball

Patent number: 8012121Abstract: 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.Type: GrantFiled: June 26, 2007Date of Patent: September 6, 2011Assignee: AngioDynamics, Inc.Inventors: Harry B.

Publication number: 20080221551Abstract: Systems and methods for the clinical treatment of individuals susceptible to or suffering from acute kidney injury are provided. Drugs, biologics, or other therapies or treatments are administered by fluid agent delivery directly to the kidneys via their arterial blood supply. Bifurcated renal artery infusion catheter devices and methods can treat kidney injury in patients with locally-delivered drugs, biologics, and other agents, so as to increase the ability of the kidneys to excrete nitrogenous waste products from the blood, and prevent or ameliorate azotemia.Type: ApplicationFiled: March 7, 2008Publication date: September 11, 2008Applicant: FlowMedica, Inc.Inventors: Harry B.

Patent number: 7104981Abstract: 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.Type: GrantFiled: October 25, 2005Date of Patent: September 12, 2006Assignee: FlowMedica, Inc.Inventors: Jeffrey M.

Patent number: 5948345Abstract: A method for making a medical balloon catheter in a single molding operation employs a parison which is molded and biaxially oriented by the use of first and second pressurization stages. The starting material is in the form of a tubular parison with a reduced diameter portion which is made of a biaxial orientable polyamide or polyetheramide material. The resulting balloon can be attached to a catheter that includes a tapered or stepped distal end without further shaping or modification of the balloon ends.Type: GrantFiled: January 5, 1998Date of Patent: September 7, 1999Assignee: Medtronic, Inc.Inventors: Kaushik A.
