  • Publication number: 20240099892
    Abstract: An apparatus includes a shaft, an expandable dilator, and at least one ventilation pathway. The shaft defines a longitudinal axis and includes a distal and proximal ends with at least one shaft lumen. The expandable dilator includes body with its own proximal and distal ends. The body is configured to transition between a contracted state and an expanded state. The body is configured to dilate a Eustachian tube of a patient in the expanded state. The at least one ventilation pathway is configured to provide ventilation from the distal end of the body to the proximal end of the body when the body is in the expanded state. In some examples, the ventilation pathway includes a set of transversely oriented vent openings formed through the shaft. In some other examples, the ventilation pathway includes a space defined between one or more radially outwardly protruding features of the expandable dilator.

  • Patent number: 5705253
    Abstract: Disclosed is a video tape suitable for use in high speed contact duplication. The magnetic layer comprises a magnetic pigment dispersed in a polymeric binder at amounts of magnetic pigment between 75 and 88 percent by weight of the magnetic layer with a total pigment loading (magnetic+nonmagnetic pigments) of at least 80 percent by weight. The tape is provided with a backside coating comprising at least two nonmagnetic pigments dispersed in a polymeric binder, the first nonmagnetic pigment, being a conductive material and having a relatively small particle size of between about 0.015 and 0.15 .mu.m, and the second nonmagnetic pigment having a relatively large particle size of between about 0.15 and 1.5 .mu.m. The magnetic layer has a lubricant absorption value of at least 4 and a surface roughness of between 5 and 15 nm. The backside coating has a surface roughness of between 10 and 150 nm.

  • Patent number: 4901257
    Abstract: Method and apparatus for calibrating a temperature measuring device by operating a heat source at a preset temperature as determined by a temperature sensing resistor and a digitally calculated temperature which varies nonlinearly with the resistance of the resistor, and obtaining the coefficients for the calculation by operating the device at a preset temperature and comparing this temperature with that of a standard temperature measuring device.
