Patent number: 12350178Abstract: An implantable metallic braid is formed out of groups of filaments of a first material, groups of filaments of a second material different from the first material, and groups of filaments of a third material different from the first material and the second material. The filaments are braided together by a braiding machine and are arranged in a starting filament arrangement on the braiding machine before braiding begins, wherein the first material is a radiopaque material, the second material is a support material, and the third material is a DFT comprising the first and second materials. Different arrangements of the filaments in the starting filament arrangement and in the braid result in different levels of detail that can be observed in images of the braid, wherein certain arrangements of the filaments result in enhanced radiopacity without affecting other mechanical properties of the braid.Type: GrantFiled: September 21, 2023Date of Patent: July 8, 2025Assignees: Stryker Corporation, Stryker European Operations LimitedInventor: Jeffrey Lu

Publication number: 20240130880Abstract: Methods and systems for delivering a tubular implant to a target location in a body lumen, wherein the tubular implant has a delivery length when in a radially collapsed, delivery configuration, and a foreshortened length shorter than the delivery length when in a radially expanded, implanted configuration. Respective markers are provided on a delivery catheter and on the tubular implant which provide a visual indication of the landing location of a foreshortened length of a last proximal portion of the tubular implant prior to implanting the last proximal portion. This allows the clinician to determine if the landing location of the last proximal portion is clinically desirable prior to fully implanting the tubular implant.Type: ApplicationFiled: December 13, 2023Publication date: April 25, 2024Applicants: STRYKER CORPORATION, STRYKER EUROPEAN OPERATIONS LIMITEDInventors: Siddharth Loganathan, Beth Oldford, Jeffrey Lu, Rajan Chandrasekaran

Patent number: 9937254Abstract: Water-soluble supramolecular complexes formed from a water soluble block copolymer and at least one associative gelling adjuvant. The copolymer includes at least two blocks of polyethylene oxide and at least one block of polypropylene oxide. The adjuvant has a water solubility less than 0.5 g/100 ml at 20° C. When combined with water, the complexes form a transparent reversely thermo-reversible hydrogel or solution that may be repeatedly hydrated and dehydrated. The hydrogel exhibits improved gelling efficiency and enhanced solubility and/or stability for sparely soluble and insoluble pharmaceutical agents. The complexes are useful in a variety of pharmaceutical and cosmetic products and applications and may be combined with an effective amount of a cosmetic, medicament, or diagnostic in a solid dosage form.Type: GrantFiled: January 17, 2017Date of Patent: April 10, 2018Assignee: Broda Technologies Co., Ltd.Inventors: Shao Xiang Lu, Jeffrey Lu, Letian Liu
