Patent number: 11918731Abstract: An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient as a patient inhales. The aerosol delivery system includes a pump coupled to the aerosol generator that pumps the fluid to the aerosol generator, and a breath sensor that emits a signal as the patient breathes. A controller couples to the aerosol generator, the pump, and the breath sensor. In operation, the controller receives the signal from the breath sensor, controls a flow of fluid to the aerosol generator in response to the signal, and controls the aerosol generator to start aerosolizing the fluid before the patient inhales.Type: GrantFiled: May 28, 2021Date of Patent: March 5, 2024Assignee: Stamford Devices Ltd.Inventors: Shaun Porter, Louise Sweeney, Ronan MacLoughlin, Jim Fink, Aidan Duffy, Claire Lillis, Conor Duffy, Fran Keating

Publication number: 20230381482Abstract: An introducer tool for use with a vascular entryway system and method. While a radially self-expanding distal section of an aspiration catheter is in a radially non-compressed state, an aspiration catheter is pre-assembled into a flared proximal section of the introducer tool. Together as a single unit, the introducer tool with the aspiration catheter pre-assembled therein is introduced into a hemostasis valve and a tapered guide sheath luer. The aspiration catheter is pushed through the introducer tool. While traversing the compressing section of the lumen of the shaft of the introducer tool and/or the tapered inner profile of a tapered guide sheath luer, the radially self-expanding distal section of the aspiration catheter is radially compressed to be receivable in a lumen of a guide sheath catheter. While the radially self-expanding distal section is radially compressed, the aspiration catheter is slid into the lumen of the guide sheath catheter.Type: ApplicationFiled: May 4, 2023Publication date: November 30, 2023Inventors: Patrick GRIFFIN, David VALE, Karl KEATING, Thomas O'MALLEY, Lucy CARRAGHER, Ronald KELLY, Aidan DUFFY, Declan LEE, Paulo RATOLA

Publication number: 20230285704Abstract: A patient interface (1) is for aerosol treatment, having a base (2) to surround the patients mouth and nose and engage the skin with a resilient seal, and with a strap (8) to attach to a patients head. There is a support (3) on and across the base for supporting an aerosol delivery head with prongs (4, 5). An enclosed volume is formed in the interface by attachment of a shell (10), which has an extraction port (11) for attachment of an extraction system (20) to extract gas from this volume. An HFNT system includes a patient interface surrounding the nose and mouth and an aerosol delivery apparatus (4, 6), an extraction apparatus (20), and a controller (100) to control delivery of aerosol and/or gas to the interface and to extract gases from a volume enclosed by the interface. Because of the fully sealed volume within the interface there are a wide range of control scenarios possible, using pressure sensing in the volume, bypass valves (201), dynamically-controllable nebulizer (203).Type: ApplicationFiled: August 20, 2021Publication date: September 14, 2023Applicant: STAMFORD DEVICES LIMITEDInventors: John POWER, Aidan DUFFY, Micheal CASEY

Publication number: 20230001107Abstract: A nebulizer has an aerosol generator mounted in a housing, and has a vibratable aperture plate mounted to an annular support and to which is attached a vibration generator piezo. A downstream annular resilient seal is mounted between the housing and the washer on a side of the aperture plate opposed to the liquid supply reservoir. An upstream resilient seal is in the form of a gasket and is mounted between the washer and the housing reservoir, and has an opening forming part of a throat over the aperture plate. The gasket has a washer-shaped body extending radially from a downstream-extending rim adjacent the aperture plate. There are two upwardly-directed ridges for engagement with a housing surface, and the gasket is configured so that when under axial compression the opening internal surface is tapered inwardly in a flow direction to form a funnel shape.Type: ApplicationFiled: March 22, 2021Publication date: January 5, 2023Applicant: STAMFORD DEVICES LIMITEDInventors: Diarmuid CONNOLLY, Colm CARMODY, Finbarr MAGUIRE, Aidan DUFFY

Publication number: 20220016365Abstract: A dispensing apparatus is for use by users to take a chamber, fill the chamber with an aerosolized vaccine or other medicament, and dispose of used chambers. A display provides instructions to encourage prompt inhalation by the user from a dispensed and filled chamber. The apparatus allows very fast administration of vaccines to large numbers of people. The aerosol dispenser apparatus detects the chamber is in correct position and delivers a pre-determined dose of aerosol. Once the dose is delivered a visual and/or audible indicator informs the user that the chamber is filled and that they can take the inhalation. The single dose aerosol chamber is optimized for efficient administration of an aerosol.Type: ApplicationFiled: July 9, 2021Publication date: January 20, 2022Applicant: Stamford Devices LimitedInventors: John POWER, Ronan MacLOUGHLIN, Michael CASEY, Conor DUFFY, Aidan DUFFY
