Patent number: 10932810Abstract: A thrombectomy catheter system is disclosed which includes a catheter having an exhaust lumen, an infusion lumen and a high pressure tube. The high pressure tube includes a nozzle orifice for forming a high pressure jet of fluid for cutting occlusive material from within a body lumen. The nozzle orifice is positioned to direct the high pressure jet of fluid into the distal end of the exhaust lumen which creates a suctioning effect. The infusion lumen replaces fluid that is removed from the body lumen through the exhaust lumen by a suctioning effect created by the fluid jet.Type: GrantFiled: August 31, 2018Date of Patent: March 2, 2021Assignee: Covidien LPInventors: Arnaz S.

Publication number: 20150225684Abstract: A method for non-invasive growth measurement of organisms in an apparatus for growing and harvesting organisms or substances derived from such organisms. The organisms are comprised in an aqueous medium in a vessel, the method comprising the steps of: a) Providing means for measuring the opacity of the aqueous medium in order to estimate a growth rate of the organisms; b) The means for measuring the opacity are arranged in the apparatus such that they are located at predetermined locations relative to the vessel; c) The means for measuring the opacity are calibrated to account for refraction, absorbance and reflection caused by the vessel at the predetermined location. Finally the method also allows for measuring the opacity of the aqueous medium at the predetermined location.Type: ApplicationFiled: September 18, 2013Publication date: August 13, 2015Applicant: Spicer Consulting LtdInventors: Andrew Spicer, Denis Spicer, John Sacket, Daniel Hutton, Mark Zaremba

Patent number: 6496567Abstract: An advanced resource management system for an interactive voice response (IVR) service node allows multiple network ports to be served by one application port thereby increasing efficiency. An IVR with a plurality of network ports can now be efficiently configured with a plurality of application ports with varying capabilities. The resource management system determines which of the plurality of application ports on the service node has the capability to service an incoming call and then dynamically assigns a time slot to one of the network ports and to one of application ports to perform IVR services. The dynamic allocation of application ports to network ports also allows for a more simplified connection of the service node to the telecommunications network in which it is deployed.Type: GrantFiled: May 7, 1998Date of Patent: December 17, 2002Assignee: MCI Communications CorporationInventors: Greg Bjornberg, Patrick Hamilton, Daniel Hutton

Patent number: 6427002Abstract: A next generation service node (NGSN) for providing advanced interactive voice response (IVR) services within a telecommunications network. The NGSN includes intelligent peripherals implemented as network audio servers, and application servers which execute customer application files to perform IVR services. The NGSN provides reliability through redundancy of application servers, including automatic application server failover within a node, and automatic node failover between NGSNs. The NGSN features include modular software and hardware architecture with internal function encapsulation. This allows multiple vendors products to be used and provides a common signaling interface to be used to any switch network. Other NGSN features include an open systems architecture with improved scaleability and increased application processing capability.Type: GrantFiled: May 7, 1998Date of Patent: July 30, 2002Assignee: WorldCom, Inc.Inventors: Jeffrey W. Campbell, Henry N. Fly, Allen Holmes, Daniel Hutton, Judy A. Moldenhauer, Phyllis D. Santa
