Publication number: 20200069420Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.Type: ApplicationFiled: October 14, 2019Publication date: March 5, 2020Inventors: Tamir S. Levi, Son V. Nguyen, Netanel Benichou, David Maimon, Ziv Yohanan, Nikolay Gurovich, Bella Felsen, Larisa Dadonkina, Ron Sharoni, Elena Sherman

Publication number: 20200051854Abstract: Low capacitance and high reliability interconnect structures and methods of manufacture are disclosed. The method includes forming a copper based interconnect structure in an opening of a dielectric material. The method further includes forming a capping layer on the copper based interconnect structure. The method further includes oxidizing the capping layer and any residual material formed on a surface of the dielectric material. The method further includes forming a barrier layer on the capping layer by outdiffusing a material from the copper based interconnect structure to a surface of the capping layer. The method further includes removing the residual material, while the barrier layer on the surface of the capping layer protects the capping layer.Type: ApplicationFiled: October 18, 2019Publication date: February 13, 2020Inventors: Daniel C.

Patent number: 10548727Abstract: The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valveāi.e., the mitral valve and the tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. Finally, there is a proximal anchoring feature to fix the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.Type: GrantFiled: April 12, 2017Date of Patent: February 4, 2020Assignee: Edwards Lifesciences CorporationInventors: Vivian Khalil, Erin M. Spinner, Neil S. Zimmerman, Alexander J. Siegel, Son V. Nguyen

Publication number: 20200028069Abstract: Magnetic tunnel junction pillars are encapsulated by an oxidized diffusion barrier layer. Oxygen within the encapsulating material is used to oxidize metallic residue outside the pillars, converting the residue to a non-conductive material such as a metal oxide or metal oxynitride. Selective deposition of manganese on the metal layers of the pillars can be followed by oxidation of the manganese to form a manganese oxide diffusion barrier. Alternatively, manganese deposition can be followed by deposition of silicon dioxide and subsequent annealing to form a manganese silicate diffusion barrier.Type: ApplicationFiled: September 27, 2019Publication date: January 23, 2020Inventors: Son V. Nguyen, Alexander Reznicek, Donald F. Canaperi

Publication number: 20200000585Abstract: A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.Type: ApplicationFiled: September 13, 2019Publication date: January 2, 2020Inventors: Ilia Hariton, Netanel Benichou, Yaacov Nitzan, Bella Felsen, Diana Nguyen-Thien-Nhon, Rajesh A.

Publication number: 20190365530Abstract: A prosthetic heart valve includes an annular frame that has an inflow end and an outflow end and is radially compressible and expandable between a radially compressed configuration and a radially expanded configuration. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame and adapted to seal against surrounding tissue when the prosthetic heart valve is implanted within a native heart valve annulus of a patient. The sealing member can include a mesh layer and pile layer comprising a plurality of pile yarns extending outwardly from the mesh layer.Type: ApplicationFiled: August 31, 2018Publication date: December 5, 2019Inventors: Lien Huong Thi Hoang, Son V.
