Publication number: 20240074784Abstract: According to some embodiments, the present technology includes devices and systems for removing obstructive material from a blood vessel lumen. For example, the system can comprise a first elongated member, a second elongated member, and a cutting element configured to cut obstructive material at the treatment site. Rotation of the second elongated member relative to the first elongated member, or vice versa, can cause the cutting element to expand away from a longitudinal axis of the second elongated member. The system can further include an expandable positioning element configured to be intravascularly delivered to the treatment site, where the positioning element can be configured to expand into apposition with the vessel wall to position the cutting element closer to the obstructive material than before expansion of the positioning element.Type: ApplicationFiled: March 10, 2023Publication date: March 7, 2024Inventors: Daniel T. Lagoe, Herbert M. Mendoza, Michi E. Garrison, Kent D. Dell, Jeffrey M. Elkins

Publication number: 20220331555Abstract: Intravascular devices and methods for intramural delivery of dissection fluids and infusates are disclosed herein. In some embodiments, the systems include an infusion assembly that can access a position in vessel adjacent an infusion site and advance a tissue manipulation component into the infusion site to deliver a therapeutic infusate. The infusion site can be an intraluminal space, such as within an obstructive material, adjacent the obstructive material, and/or within a boundary layer between the obstructive material and a vessel wall. The infusion assembly can further deliver an infusate that includes a therapeutic drug or other agent into the infusion site.Type: ApplicationFiled: April 29, 2022Publication date: October 20, 2022Inventors: Fletcher T.

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: 8518011Abstract: 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.Type: GrantFiled: August 28, 2009Date of Patent: August 27, 2013Assignee: AngioDynamics, Inc.Inventors: Harry B.

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: 7771401Abstract: Renal infusion systems include an infusion catheter having a bifurcated distal end with a first branch and second branch, the branches being biased to deploy laterally when unconstrained. Systems also include a delivery sheath having a lumen which receives the infusion catheter and constrains the first branch and second branch. A distal opening of the delivery sheath is formed asymmetrically to allow one of the first and second branches to open laterally while the other of the branches remains constrained. Methods of using renal infusion systems are also provided.Type: GrantFiled: June 5, 2007Date of Patent: August 10, 2010Assignee: AngioDynamics, Inc.Inventors: Neema Hekmat, Harry B.

Patent number: 7766961Abstract: 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.Type: GrantFiled: December 5, 2005Date of Patent: August 3, 2010Assignee: Angio Dynamics, Inc.Inventors: Samir Patel, Harry B.
