Patent number: 11672702Abstract: An aqueous humor outflow device includes an arcuate scaffold that fits within a conventional aqueous humor outflow pathway of a mammalian eye to receive aqueous humor from a trabecular meshwork of the mammalian eye and allow flow of the aqueous humor through the arcuate scaffold to one or more collector channels that originate in a posterior wall of a Schlemm's canal. The arcuate scaffold includes a first arcuate rail, and a second arcuate rail spaced apart from, and substantially parallel to, the first arcuate rail. The first and second arcuate rails each have an anterior edge that is adjacent to the trabecular meshwork when inserted in the Schlemm's canal, and a posterior edge that is adjacent to the posterior wall of the Schlemm's canal. Structural components coupled to the first arcuate rail and the second arcuate rail maintain the respective anterior and posterior edges of the first and second arcuate rails spaced apart from, and substantially parallel to, each other.Type: GrantFiled: June 10, 2022Date of Patent: June 13, 2023Assignee: eyeFlow, Inc.Inventors: Douglas Cali, David Dean Richardson

Patent number: 11385401Abstract: The present disclosure relates to a MCF, including a plurality of cores, an outer cladding or tube, diffusion barriers, and claddings. The diffusion barriers and claddings are designed so that unwanted migration of dopants from the inner cladding to the outer cladding or tube is reduced, or that unwanted migration of dopants from the cores to the outer cladding or tube is reduced. The doping levels of the various components of the MCF can be controlled in order to reduce dopant migration. The reduction in dopant gradients reduces the migration of dopants and bubbles to the interfaces between the inner claddings, the outer cladding or tube, and the cores.Type: GrantFiled: December 2, 2020Date of Patent: July 12, 2022Assignee: Alcon Inc.Inventors: Alireza Mirsepassi, Dean Richardson
