Patent number: 9399105Abstract: A nasal mask system includes an interface (80) adapted to form an air interface with a patient's nose, and a mouth seal (10) adapted to form a seal (20) with the patient's mouth. The mouth seal (20) is communicated with the interface (80) via a one-way air path (40) that allows exhausted air from the mouth seal to pass into the interface (80) but prevents air from the interface (80) from passing into the mouth seal (10).Type: GrantFiled: April 1, 2010Date of Patent: July 26, 2016Assignee: ResMed LimitedInventor: Robert Frater

Patent number: 7993393Abstract: A highly flexible tissue-type heart valve is disclosed having a structural stent in a generally cylindrical configuration with cusps and commissures that are permitted to move radially. The stent commissures are constructed so that the cusps are pivotably or flexibly coupled together at the commissures to permit relative movement therebetween. The stent may be cloth-covered and may be a single element or may be made in three separate elements for a three cusp valve, each element having a cusp portion and two commissure portions; adjacent commissure portions for each pair of adjacent stent element combining to form the stent commissures. If the stent has separate elements their commissure portions may be pivotably or flexible coupled, or may be designed to completely separate into independent leaflets at bioresorbable couples. The cloth covering may have an outwardly projecting flap that mates with valve leaflets (e.g., pericardial leaflets) along the cusps and commissures.Type: GrantFiled: September 10, 2009Date of Patent: August 9, 2011Assignee: Edwards Lifesciences CorporationInventors: Alain F. Carpentier, Stefan G. Schreck, Richard S. Rhee, Diana Nguyen-Thien-Nhon, Hung Ly Lam, William J. Recktenwald, Robert Frater

Publication number: 20070215161Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.Type: ApplicationFiled: June 15, 2005Publication date: September 20, 2007Applicant: ResMed LimitedInventors: Robert Frater, Joanne Drew, Philip Kwok, Patrick Mc Auliffe, Aaron Davidson, Robin Hitchcock, Michael Gunaratnam

Publication number: 20070193339Abstract: A system and method for measuring contact pressures between two surfaces, and especially, between the body and a device resting on the body, e.g., the skin and a breathable gas mask. A deformable, resilient probe having a flow passage therein is initially placed between the two surfaces such that the flow passage is blocked. Fluid pressure within the probe is then increased until the pressure in the probe overcomes the contact pressure between the two surfaces, such that fluid begins to flow through the flow passage in the probe. The pressure at which the fluid begins to flow through the flow passage in the probe is recorded as the contact pressure between the two surfaces. Contact pressure maps created using this apparatus and method may be used to create anthropometric models of the face and other body parts.Type: ApplicationFiled: April 25, 2007Publication date: August 23, 2007Applicant: ResMed LimitedInventors: Andrew Selim, Patrick McAuliffe, Milind Raje, Robert Frater

Publication number: 20070142741Abstract: A method and apparatus for treating sleep disordered breathing. An arousal index is determined for use in an outer loop of a control algorithm, the arousal index being a measure of the frequency of sleep arousals. The respiratory airflow signal in an inner loop of the control algorithm is monitored to detect an airway obstruction.Type: ApplicationFiled: November 25, 2004Publication date: June 21, 2007Inventors: Michael Berthon-Jones, Gordon Malouf, Peter Bateman, David Bassin, Robert Frater, Steven Farrugia

Publication number: 20060213520Abstract: A mask system for delivering air to a user includes a suspension mechanism to allow relative movement between a face-contacting cushion and a mask shell. The suspension mechanism also provides a predetermined force to the cushion that is a function of mask pressure, displacement of the cushion or both.Type: ApplicationFiled: May 9, 2006Publication date: September 28, 2006Applicant: ResMed LimitedInventors: Robert Frater, Joanne Drew, Michael Gunaratnam

Publication number: 20050081858Abstract: A respiratory mask assembly for use in the delivery of non-invasive positive airway pressure to a user. The assembly includes a rigid shell having a channel portion defined by an inner wall, an outer wall and a channel floor, a face-contacting cushion acting to space the shell away from the user's face and a sealing tab extending from the cushion to engage a portion of the shell to provide a continuous airtight seal between the cushion and the shell. A retaining ring within the mask assembly is configured to secure the cushion to the shell. The retaining ring has a first portion including at least one clip configured to pass through at least one slot portion such that an underside surface of the at least one clip engages a section of the shell when the retaining ring is positioned within the channel.Type: ApplicationFiled: October 12, 2004Publication date: April 21, 2005Applicant: ResMed LimitedInventors: Milind Raje, Timothy Fu, Amal Amarasinghe, Joanne Drew, Robert Frater, Memduh Guney, Clive Solari

Patent number: 6512795Abstract: In compressed video signals, lost or erroneous information in a current image signal received at the receiving end of a transmission channel is concealed by identifying a motion compensated equivalent region in a previously transmitted image and substituting the equivalent region as a prediction of the lost or erroneous information in the current image.Type: GrantFiled: June 26, 2000Date of Patent: January 28, 2003Assignees: Unisearch Limited, Commonwealth Scientific and Industrial Research OrganisationInventors: Jian Zhang, John Frederick Arnold, Michael Robert Frater

Patent number: 4185636Abstract: A plurality of organizers each formed with an arcuate support member upon which a selected number of suture holding devices are positioned in spaced relationship one to the other, are each designed to be disposed proximate an area of a body upon which surgery is to be performed to faciliate speedy and orderly control of interrupted sutures and needles utilized during the surgical procedure. Each holding device includes a pair of spaced wall members and a resilient holding member disposed in compression therebetween in such a manner that sutures can be releasably held between the resilient member and the adjacent wall member surface. Additional valuable time for surgical procedures involving insertion of artificial heart valves can be saved by utilizing a heart valve holder having a plurality of circumferentially spaced legs, to which an artificial heart valve can be releasably held by sutures.Type: GrantFiled: December 29, 1977Date of Patent: January 29, 1980Assignee: Albert Einstein College of Medicine of Yeshiva UniversityInventors: Shlomo Gabbay, Robert Frater
