  • Patent number: 11517476
    Abstract: A glaucoma drainage device includes an elongated body extending axially from a distal end to a proximal end. The distal end forms a wedge with a leading distal edge. During implantation of the device into the suprachoroidal space of the eye, the wedge can facilitate penetration into and spreading open the tissue of the suprachoroidal space. The elongate body has one or more outer surfaces that define at least one open groove extending from at or near the proximal end towards the distal end of the body. With the distal end of the elongate body located in the suprachoroidal space of the eye and the distal end of the elongate body extending into the anterior chamber of the eye, the at least one open groove is configured such that aqueous humor flows along the open groove from the anterior chamber of the eye to the suprachoroidal space of the eye.

  • Patent number: 11439735
    Abstract: A system for calculating cardiac output of a patient on an extracorporeal blood oxygenation circuit includes measuring first oxygenated blood flow rate by a pump in the extracorporeal circuit and a corresponding arterial oxygen saturation and recirculation in the extracorporeal circuit, then changing the pump flow rate, such as decreased, to produce a corresponding change in arterial oxygen saturation (wherein such change is outside of normal operating variances or drift), which change in the arterial oxygen saturation and recirculation are measured. From the first flow rate and the second flow rate along with the corresponding measured recirculation and the arterial oxygen saturation, the CO of the patient can be calculated, without reliance upon a measure of venous oxygen saturation. The system also includes an accommodation of oxygenation by the lungs of the patient during the extracorporeal blood oxygenation.

  • Patent number: 11432967
    Abstract: Disclosed embodiments may relate to devices, systems, and methods for providing negative-pressure therapy simultaneously to a plurality of tissue sites using a single negative-pressure source. For example, a fluid bridge may comprise a plurality of distal ends, each configured to interact fluidly with a tissue site. In some embodiments, each distal end may have an aperture. The bridge may also comprise a port for entry of negative pressure into the enclosed space of the bridge. In some embodiments, each distal end may comprise a one-way valve. The enclosed space of the fluid pathway between the distal ends and the port may be supported in some embodiments, to prevent collapse due to negative pressure and/or compression.

  • Patent number: 11419762
    Abstract: Devices and methods to remove trabecular meshwork to treat glaucoma and other conditions which may not utilize cutting elements when stripping the trabecular meshwork. The trabeculorhexis parts tissue by applying non-cutting shear and tension to the tissue to disinsert the tissue from its attachments. Reducing or eliminating the need for sharp cutting implements in the eye reduces the likelihood of incisional bleeding, iris and scleral tissue maceration and further inadvertent tissue damage of the gonio structure of the eye. In another aspect, a cutting element may be used to form a circumferential slit in a wall of Schlemm's canal in conjunction with removal of trabecular meshwork or independently.
