Patent number: 12268617Abstract: Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.Type: GrantFiled: February 19, 2024Date of Patent: April 8, 2025Assignee: Covidien LPInventors: Xiaodong Ma, Min-Shyan Sheu, Lincoln Eramo, John Wainwright, Junwei Li

Publication number: 20240033713Abstract: The invention relates to a stationary phase medium for adsorption chromatography, which is in form of porous microspheres suitable for being packed into a chromatographic column. The porous microspheres are made of cross-linked polymeric material and formed with interconnected macropores to constitute a porous network. The invented porous microspheres have a characteristic size ratio of porous network diameter to microsphere particle size, and the porous network is in fluid communication with the ambient via multiple openings, so that molecules are convectively transported through the porous network. Accordingly, the invention shows low back pressure and high binding capacity to molecules at high mobile phase velocities.Type: ApplicationFiled: July 25, 2023Publication date: February 1, 2024Inventors: Hui CHEN, Min-Shyan SHEU, Tsung-Han TU, Jih-Hsien LEE, Bruce C.S.

Publication number: 20230338924Abstract: The invention relates to a stationary phase medium for adsorption chromatography, which is in form of porous particles suitable for being packed into a chromatographic column. The porous particles are made of cross-linked polymeric material and formed with interconnected macropores to constitute a porous network, through which a mobile phase fluid may flow in a convective manner. The porous particles are substantially free of diffusive pores and, thus, the mass transfer through the porous network is governed by convection alone. The porous particles are fabricated to have irregular granular configurations with rough outer surfaces, so that the convective flow between the porous particles will not be impeded during chromatography process.Type: ApplicationFiled: April 26, 2022Publication date: October 26, 2023Inventors: Tsung-Han TU, Chia-Wei LIN, Shih-Yu WANG, Hui CHEN, Min-Shyan SHEU, Shih-Horng YANG

Patent number: 11376141Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.Type: GrantFiled: June 26, 2020Date of Patent: July 5, 2022Assignee: COVIDIEN LPInventors: John Wainwright, Todd Mendelson, Kurt Haggstrom, Masoud Molaei, Victoria Schuman, Min-Shyan Sheu

Patent number: 11236184Abstract: The invention relates to production of a porous microstructure using the high internal phase emulsion (HIPE) templating technology. The invented method involves subjecting an emulsion prepared by emulsification of two immiscible phases to forced sedimentation, such as subjecting the emulsion to centrifugation, so as to increase the volume ratio of the dispersed phase to the continuous phase to obtain a high internal phase emulsion (HIPE), following by curing the continuous phase, whereby the porous microstructure thus produced has an increased porosity.Type: GrantFiled: February 24, 2021Date of Patent: February 1, 2022Assignee: Tantti Laboratory Inc.Inventors: Shih-Yu Wang, Hui Chen, Pang Lin, Min-Shyan Sheu
