Patent number: 11896197Abstract: An electrical device includes a memory storing a value indicative the remaining available rated capacity of one or more batteries. The stored value is changed in use to reflect reducing capacity. The initial stored value is chosen so that there is a very high (e.g. >99.9%) confidence that the one or more batteries will provide at least the capacity indicated by the initial stored value. This reduces the chance of failure during emergency procedures. The one or more batteries may be integral to the electrical device. An override facility is provided.Type: GrantFiled: June 23, 2021Date of Patent: February 13, 2024Assignee: Covidien AGInventors: Matthew John Ross McGrath, Peter Douglas Colin Inglis, Brian Alan Laffoley

Patent number: 11709120Abstract: Devices, systems, and methods are disclosed for improved laser speckle imaging of samples, such as vascularized tissue, for the determination of the rate of movement of light scattering particles within the sample. The system includes a structure adjoining a light source and a photo-sensitive detector. The structure can be positioned adjacent the sample (e.g., coupled to the sample) and configured to orient the light source and detector relative the sample such that surface reflections, including specular reflections and diffuse reflections, are discouraged from entering the detection field of the detector. The separation distance along the structure between the light source and the detector may further enable selective depth penetration into the sample and biased sampling of multiply scattered photons. The system includes an operably coupled processor programmed to derive contrast metrics from the detector and to relate the contrast metrics to a rate of movement of the light scattering particles.Type: GrantFiled: April 4, 2017Date of Patent: July 25, 2023Assignee: Covidien AGInventors: Tyler Bywaters Rice, Sean Michael White, Bruce Yee Yang

Patent number: 11510563Abstract: Disclosed is a laryngoscope insertion section having a curved superior surface, a curved inferior surface, and a channel extending from the proximal end the channel having an inferior surface with a greater curvature than the curvature of the inferior surface. The insertion section is compatible with laryngoscope hardware optimized for indirect viewing, yet enables direct viewing. The distance between the inferior and superior surfaces is at a maximum within the intermediate portion, and enables the dimensions of the proximal and distal portions to be minimized. Thus, the intermediate portion, located in the patient's oral cavity in use, is provided with greatest depth and strength where the greatest forces are received, whereas the distal and proximal portions are of reduced dimensions to minimize trauma to the patient's airway and mouth areas, respectively. Structural features providing the insertion section with improved strength, with a minimum of material and size, are also disclosed.Type: GrantFiled: August 11, 2020Date of Patent: November 29, 2022Assignee: Covidien AGInventors: Matthew John Ross McGrath, Peter Douglas Colin Inglis
