Abstract: An ophthalmic surgical system includes at least one light source. The light source is configured to output light towards a fluidics cassette so a first portion of the light reflects from a deflectable diaphragm of the fluidics cassette, and a second portion of the light reflects from a reference portion of the fluidics cassette. The diaphragm is configured to deflect relative to the reference portion in response to a pressure associated with a fluid within the fluidics cassette. At least one sensor is configured to receive the first portion of the light reflected from the diaphragm and the second portion of the light reflected from the reference portion. A computing device in communication with the sensor is configured to determine the pressure associated with the fluid within the fluidics cassette based on the received first and second portions of the light. Associated devices, systems, and methods are also disclosed.

Abstract: A surgical cassette clamping system includes a mounting plate having a first side and a second side. A bracket system may be disposed adjacent the first side of the mounting plate. A clamp motor may be disposed adjacent the mounting plate and fixed relative to the mounting plate. The clamp motor may be operably connected to the bracket system to displace the bracket system relative to the mounting plate. The system may also include a plurality of pivot arms pivotably connected to the bracket system and extending adjacent the second side of the mounting plate. An engagement portion may be attached to each of the plurality of pivot arms that cooperatively engages the second side of the mounting plate, the engagement portion being operable to pivot the pivot arms when the bracket system moves relative to the mounting plate.

Abstract: A hydraulically-driven Intra-Ocular Lens (IOL) insertion tool includes a body, a chamber within the body, a first fluid port providing fluid communication into the chamber, a piston positioned within the chamber and arranged to move within the chamber in response to the introduction or removal of fluid from the chamber, and an elongated member. The elongated member includes a distal end comprising an intra-ocular lens interface and a proximal end connected to the piston such that movement of the piston within the chamber causes corresponding movement of the elongated member.

Abstract: A method of irrigating a surgical site and aspirating fluid from the surgical site. The method includes directing a fluid through an aspiration conduit in a phacoemulsification hand piece using a vacuum pressure created from a pump in the hand piece interfacing with the aspiration conduit and directing an irrigation fluid through an irrigation conduit in the hand piece using a pressure created from the pump interfacing with the irrigation conduit. The method also includes increasing an irrigation fluid flow through the irrigation conduit by activating the pump in the hand piece, detecting a pressure associated with a surgical site using a sensor, and controlling intraocular pressure (IOP) by adjusting the pump speed based on the detected pressure.

Abstract: A physiological monitor device includes a central processing unit (CPU) that is configured to control operation of the device, a display screen, and one or more computer readable data storage media storing software instructions that, when executed by the CPU, cause the device to: create or modify a patient profile, select a patient test, store one or more test parameters selected or entered for the patient test, store one or more thresholds selected or entered for at least one of the test parameters, store one or more instructions for the patient, start the test, display test results while the test is in progress, determine whether any of the test parameters exceed limits set by the one or more thresholds, take one or more actions when it is determined that one or more of the test parameters exceed the limits set by the one or more thresholds, provide a summary and analysis of the test results, and send the test results to a computing device.

Abstract: Methods for growing living organisms in a series of growing units, including delivering a fluid by continuous horizontal flow from a source of fluid to each growing unit.

Abstract: An apparatus for growing living organisms having at least one growing unit adapted to receive at least one living organism, a source of fluid, a conduit operably connecting the source of fluid and the growing unit in fluid supplying relation, and at least one system for supplying the requirements by which the living organism can grow in the growing unit.

Abstract: Systems and methods are provided for quantifying and providing indicia of ST-segment resolution in an electrocardiogram (ECG) signal. A receiver acquires an electrocardiogram (ECG) signal that includes an ST-segment. A processor processes the ECG signal to determine values for the ST-segment deviation relative to an isoelectric baseline. A user is allowed to provide a baseline signal to the processor. The processor responds to the baseline signal by marking a baseline ST-segment value corresponding to a baseline time. A user interface displays a linear graphical trend of variations in the measured ST-segment values relative to the baseline ST-segment value. In certain embodiments, the processor detects user-selected trigger events such as post-intervention ST deviation relative to the baseline time and the baseline ST-segment value, and provides indicia of the trigger event. In addition, or in other embodiments, a verbal annunciation of a percent ST-segment resolution is provided.

Abstract: In various embodiments, a device for delivering pressurized irrigation may include a squeeze plate and a pressure sensor module. The squeeze plate may move relative to the pressure sensor module to apply pressure to a flexible container (e.g., a bag of irrigation fluid) between the squeeze plate and the pressure sensor module. The pressure sensor module may include a pressure sensor to measure a force exerted on the pressure sensor module by the flexible container as pressure is applied to the flexible container from the squeeze plate. In some embodiments, the pressure sensor module may include a bag contact plate and the pressure sensor may measure a force exerted on the bag contact plate by the flexible container located between the bag contact plate and the squeeze plate. In some embodiments, the pressure sensor may sense a pressure associated with the flexible container without an intervening bag contact plate.
