Publication number: 20220104796Abstract: A method of obtaining a tissue specimen includes moving a biopsy needle through a vasculature and through a wall of a blood vessel at a target site. At the target site, the biopsy needle forms a puncture through a wall of said blood vessel at a non-perpendicular angle so that an inner-wall opening of the puncture is further downstream from an outer-wall opening of the puncture. The biopsy needle resects a portion of tissue. The biopsy needle reenters the puncture with the portion of the tissue trapped therein. The biopsy needle is withdrawn from the vasculature for subsequent inspection of the tissue.Type: ApplicationFiled: November 24, 2020Publication date: April 7, 2022Applicant: Ozca Engineering Ltd.Inventors: Oz Cabiri, Ivan Sepetka

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. Greene, Ivan Sepetka, Cathy Lei, Rupal Nguyen, Matthew J. Bradley, Stephen T. Ahlers, Carl S. Goforth, James R. Stone, Timothy Ray Nieman, Shawn Fojtik
