Patent number: 12178976Abstract: A balloon catheter is described, having a reinforced, co-axial, dual lumen design. At least one of the lumens is formed of a multilayer, tubular element in which one of the layers functions, in part, to provide radial reinforcement to the tubular element.Type: GrantFiled: August 24, 2022Date of Patent: December 31, 2024Assignee: MicroVention, Inc.Inventors: Joseph A. Gulachenski, Roland Guyon, Cathy Lei, Nelson Peralta, Tadele Haile Wolde-Meskel, Russell Corvese

Publication number: 20240197335Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.Type: ApplicationFiled: March 4, 2024Publication date: June 20, 2024Applicant: MicroVention, Inc.Inventors: Matthew J. Fitz, Cathy Lei, Joseph Gulachenski, Maricruz Castaneda, Gary Currie

Publication number: 20210322025Abstract: Blood vessel occlusion devices, systems and methods, in particular embodiments of devices for aortic occlusion. The device includes one or more locator portions and an occluder portion. The device is delivered via transcatheter delivery. The locator portion may be radially expanded using a handle and actuator at the proximal end of the delivery catheter. Tactile feedback from the locator portion is used to determine proper location of the occluder portion, for example within the abdominal aorta. The occluder is then radially expanded to occlude the vessel.Type: ApplicationFiled: June 25, 2021Publication date: October 21, 2021Applicants: MicroVention, Inc., University of Virginia Patent Foundation, United States of America as Represented by the Secretary of the Navy, Emergency Scientific LLCInventors: George R.
