Publication number: 20240099847Abstract: Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. In examples, transcatheter medical treatments may be utilized. The portion of the patient's heart may be dilated due to a myocardial infarction or other cardiomyopathy. The treatment may comprise beating-heart repair of left ventricles with ischemic or non-ischemic dilated cardiomyopathy. The treatments may include approximating papillary muscles of the heart and accommodating ventricular expansion of the heart.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Jyoti B. Rao, Alyssa E. Kornswiet

Patent number: 11561151Abstract: Systems, devices, and methods for leak testing surgical conduit grafts or valved conduits such as aortic-valved conduits with a pressurized gas such as air. Air is non-destructive and especially useful for leak testing conduits that have coatings or sealants that may be functionally impacted when exposed to fluids such as water or saline. Open ends of the conduit are clamped and sealed, and a pressurized gas introduced into an inner lumen thereof. A change in mass flow rate is measured to quantify the leakage. One end of a tubular conduit may be clamped to a fixed manifold, and the opposite end to a manifold slidably mounted to accommodate any conduit elongation when pressurized. The clamping and sealing structure may be pneumatic and/or mechanical, and complementary contoured clamp members may be used to seal a scalloped external sealing ring of an aortic conduit.Type: GrantFiled: July 19, 2021Date of Patent: January 24, 2023Assignee: Edwards Lifesciences CorporationInventors: Mark Van Nest, Alyssa E. Kornswiet, Jackie P. Lau

Publication number: 20210353408Abstract: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.Type: ApplicationFiled: July 30, 2021Publication date: November 18, 2021Inventors: Harvey H. Chen, Son V. Nguyen, Devin D. Nguyen, Diana Marie George, August R. Yambao, Jyoti B. Rao, Alyssa E. Kornswiet, Lisong Ai, Stephen W. Tang, Edward Romero, Kevin K. Dang, Meena Francis, Louis A.
