Publication number: 20220400936Abstract: An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally from the handle, wherein the handle includes an inflow port in fluid communication with the elongate shaft, the inflow port being configured to fluidly connect to a fluid inflow line, an electronically adjustable orifice associated with the inflow port, and control circuitry for receiving a signal of a current size of the electronically adjustable orifice and/or for sending a signal to change a size of the electronically adjustable orifice. The system may include a first pressure sensor disposed upstream of the electronically adjustable orifice and a second pressure sensor disposed downstream of the electronically adjustable orifice.Type: ApplicationFiled: June 15, 2022Publication date: December 22, 2022Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Troy Velazquez, Damien Fitzgerald

Publication number: 20220370706Abstract: A fluid management system may include an inflow pump providing a fluid inflow to a medical device, at least one pressure sensor, and a controller configured to receive pressure signals from the at least one pressure sensor, the pressure signals corresponding to a system pressure within the fluid management system. The controller may be configured to detect which one of a plurality of medical devices is fluidly connected to the inflow pump based on the pressure signals from the at least one pressure sensor and an rpm of the inflow pump.Type: ApplicationFiled: May 18, 2022Publication date: November 24, 2022Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: JEFFREY A. MEGANCK, LEAH FANNING, JOHN O'DONNELL, TROY VELAZQUEZ, DAMIEN FITZGERALD, LINDA MAHER, DANIELA de BARBA, PETER J. PEREIRA, NIRAJ PRASAD RAUNIYAR

Patent number: 11454610Abstract: A chemical trace detection system includes: a drift tube; a detector disposed within the drift tube; a voltage source to produce an electrical field in the drift tube; an ionizer to establish an ionization region adjacent to the electrical field; and a desorber including a sample holder to hold a sample in or adjacent to the ionization region and a sample heater to desorb particles of the sample held in the sample holder such that the desorbed particles are introduced directly into the ionization region from the sample holder to form ionized particles that are forced toward the detector by the electrical field. A regenerable dryer assembly for supplying dry drift gas to an ion mobility spectrometer is also provided that includes a regenerable dessicant material.Type: GrantFiled: May 21, 2020Date of Patent: September 27, 2022Assignee: Leidos Security Detection & Automation, Inc.Inventors: Hacene Boudries, Troy Velazquez, Anatoly Lazarevich, Dmitriy Ivashin, Andrew Anderson
