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.

Patent number: 7959628Abstract: A tissue ablation device assembly ablates a region of tissue in a body of a patient. The tissue ablation device assembly comprises an elongated body having a proximal end portion and a distal end portion. A tubular porous membrane having a porous wall with an inner surface that defines an inner space is located along the distal end portion of the elongated body. An ablation element is disposed over the porous membrane, with the ablation element having a fixed position with respect to the porous membrane. A fluid passageway extending through the elongated body and communicates with the inner space. The fluid passageway is adapted to be fluidly coupled to a pressurizeable fluid source for delivering a volume of pressurized fluid from the fluid source to the inner space. The porous membrane allows at least a substantial portion of the volume of pressurized fluid to pass through the porous wall for enhancing ablative coupling between the electrode and the region of tissue.Type: GrantFiled: June 27, 2007Date of Patent: June 14, 2011Assignee: Atrionix, Inc.Inventors: Alan K.

Publication number: 20070167913Abstract: 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.Type: ApplicationFiled: October 11, 2006Publication date: July 19, 2007Applicant: FlowMedica, Inc.Inventors: Jeffrey Elkins, Harry Goodson, Craig Ball, Aurelio Valencia, Samir Patel, Neema Hekmat

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.
