Publication number: 20180028359Abstract: A surgical system comprises a pressurized irrigation fluid source with a flexible bag located between two opposing plates. An irrigation line is fluidly coupled to the pressurized irrigation fluid source. A hand piece with an irrigation sleeve is fluidly coupled to the irrigation line. A controller controls the pressurized irrigation fluid source based on a rate of change of a source pressure associated with the pressurized irrigation fluid source and a rate of change of a linear displacement of one or both opposing plates.Type: ApplicationFiled: July 28, 2016Publication date: February 1, 2018Inventors: Raphael Gordon, Mikhail Ovchinnikov, Gary P. Sorensen, Satish Yalamanchili

Patent number: 9668599Abstract: A drinking container has a spinner mechanism that includes a spinner housing for providing a spinner chamber. A spinner disk fits securely within the spinner chamber when rotatably mounted therein. The spinner mechanism includes a fluid input through the chamber perimeter surface, and a fluid outlet for allowing the liquid out of the spinner chamber once it has contacted the spinner disk. A jet nozzle directs a liquid from the fluid input across top and bottom surfaces of the spinner disk. The spinner disk does not include paddles, but relies primarily on viscous and adhesive forces to transfer energy from the flowing liquid to the surface of the spinner disk.Type: GrantFiled: September 25, 2014Date of Patent: June 6, 2017Assignee: Ingeniri, LLCInventors: Sky Ellsworth, Daniel Massie, Claire Massie, Satish Yalamanchili

Publication number: 20160166742Abstract: Apparatuses, systems, and methods are provided for rapid venting of vacuum to mitigate occlusion break surge within a phaco fluidics aspiration system. The aspiration system may utilize a positive displacement pump to generate flow and a vent valve to vent or moderate the pressure or vacuum level based on pressure sensor feedback detected within the eye and at the pump. Embodiments described herein provide a quick-opening vent valve that produces a quick-opening flow response upon angular rotation of the quick-opening vent valve. The flow performance at the quick-opening vent valve is improved by increasing the effective cross-sectional area of the valve at near-closed valve positions. In particular, the increase in the cross-sectional area is achieved by forming a concaving edge portion to complement a circular edge of and opening of a flow channel formed through the vent valve.Type: ApplicationFiled: December 16, 2014Publication date: June 16, 2016Inventors: Gregory S. Layser, Dan White, Satish Yalamanchili

Patent number: 8998838Abstract: A drainage device for implantation in an eye of a patient to treat an ocular condition, that includes an implant body portion comprising of a valve portion. The valve portion may comprise a flexible membrane disposed and arranged in a manner to affect flow of aqueous humor through the implant body portion. The device may also include a reed valve disposed downstream of the flexible membrane. The reed valve may be configured to prevent backflow of aqueous humor toward the membrane and configured to stabilize flow by affecting pressure at the flexible membrane. In one aspect, the reed valve is configured to create backpressure at the membrane that affects the rate of flow at the flexible membrane.Type: GrantFiled: March 29, 2012Date of Patent: April 7, 2015Assignee: Alcon Research, Ltd.Inventor: Satish Yalamanchili

Patent number: 8956320Abstract: A capillary fluid flow valve may include a chamber having a first boundary surface and a second boundary surface defined by a housing. The first and second boundary surfaces may be spaced apart by a gap sized to invoke capillary action between the surfaces. The first surface may be angled relative to the second surface. The chamber may have an inlet port, an outlet port, and an air vent port. The gap at the air vent port may be smaller than the gap at the outlet port and the gap at the outlet port may be smaller than the gap at the inlet port.Type: GrantFiled: August 28, 2012Date of Patent: February 17, 2015Assignee: Alcon Research, Ltd.Inventors: Mikhail A.
