  • Patent number: 10463780
    Abstract: A system apparatus and method for determining fluid depletion in a surgical system. A surgical system may include a surgical console, display, a processor operatively coupled to the surgical console, and a surgical cassette in fluid communication with an irrigation source and an aspiration line. Certain techniques involve the processor determining a volume of fluid in the irrigation source. The processor may be configured to receive sensed measurements regarding a rate of fluid flow over time from the irrigation source, process the rate of fluid flow relative to the determined volume and produce a first signal for the display to indicate a remaining capacity of the volume of fluid. Warnings and/or alarms may be triggered if fluid volume falls below a predetermined threshold.

  • Patent number: 10449088
    Abstract: Apparatus and methods for phacoemulsification combine a phacoemulsification needle having an offset feature with a handpiece capable of producing longitudinal motion to create a hybrid phacoemulsification effect that is more efficient than conventional longitudinal handpiece-needle combinations and has been demonstrated under certain conditions to be more efficient than needles used with handpieces providing torsional motion. The phacoemulsification needle is of the type having a hollow passageway that terminates in a straight needle tip formed off-axis from the passageway, allowing the needle tip to move eccentrically when the needle is subjected to torsional or longitudinal vibratory motion. The tip may be flared or may be coextensive with the needle body. The tip may also be angled with respect to the needle body. The aspiration passageway formed through the needle body may be positioned or shaped to be off-axis from the needle body axis.

  • Patent number: 10364914
    Abstract: The disclosed subject matter relates to a valve device that includes a valve member located within a housing in which the valve member's operation can be bypassed. For example, the valve device can include a bypass device that has an input structure, a motion conversion structure, and an output structure. The input structure can include a portion configured to resiliently deform if a valve opening input force is applied to the input structure in an input direction. The motion conversion structure can be configured to convert the valve opening input force into motion of the output structure in an output direction that is non-parallel to the input direction. The output structure can be configured to move the valve member (e.g., from a closed state to an opened state in order to bypass normal valve operation) if the motion conversion structure is displaced in the input direction. The valve device can be used in various manners, and is particularly suitable for use in a patient fluid delivery system.

  • Patent number: 10363361
    Abstract: A device for the dosed dispensing of a medium (e.g., therapeutic and/or diagnostic agent) for an insulin pump is proposed. The device comprises a transporting and transferring container, a measuring element, and an adjusting element for influencing a dispensing of the medium by way of a connection to an interior space. The transporting and transferring container has a reservoir for receiving the medium. The reservoir is closed by a displaceable element. The displaceable element is movably mounted in relation to the reservoir. A relative positioning of the displaceable element in relation to the reservoir determines the interior space of the reservoir available for receiving the medium. The measuring element senses the relative positioning of the displaceable element in relation to the reservoir. The measuring element and the adjusting element interact so that the dispensing of the medium is influenced by the relative positioning sensed by the measuring element.

  • Patent number: 10342577
    Abstract: Surgical devices having a plurality of outwardly-biased flexible fins capable of inward movement such that the fins converge to provide both a passageway for surgical instruments to traverse towards a surgical site, and provide a substantially impermeable seal, thus providing for fluid retention during the surgical procedure. The outwardly-biased flexible fins provide for soft tissue compression, decreasing the length of the lumen or passageway through which instruments pass, allowing for a wider range of movement of instruments and better access to the surgical site, especially in patients with greater amounts of fat tissue that would otherwise require longer lumen lengths in prior art endoscopic cannulas.

  • Patent number: 10327948
    Abstract: A medical device fluid sensing system in provided. The system includes a transmitter array positioned in association with a fluid maintaining device, such as a reservoir in a cassette. Electrical circuitry is connected to the transmitter array and configured to cause the transmitter array to transmit light energy at a predetermined wavelength and producing a desired absorption coefficient based on expected conditions within the fluid maintaining device. The system also includes a receiver array configured to receive light energy transmitted through the fluid maintaining device and originating from the transmitter array, and a controller configured to determine fluid level in the fluid maintaining device based on conditions sensed by the receiver array. In one embodiment, three transmitters and three matching sensors are provided in a surgical cassette, and when optical energy having predetermined characteristics is provided to the transmitter array, the presence or absence of fluid is determined.
