  • Patent number: 11925580
    Abstract: A system for preparation of an implant and ab interno insertion of the implant into an eye including a handle having one or more actuators and an elongated shaft having an outer sheath and an elongate member positioned within a lumen of the tubular outer sheath. The system includes a recess sized for holding a patch of material fixed relative to the handle and a cutting member movable relative to the handle and to the recess. The cutting member cuts the patch of material into an implant as the cutting member moves towards a cutting configuration. The implant, once cut, is axially aligned with the lumen of the tubular outer sheath. The inner elongate member is movable relative to the tubular outer sheath to advance the implant into a deployment position in the lumen of the tubular outer sheath for delivery into the eye. Related devices and methods are provided.

  • Publication number: 20230181358
    Abstract: A method for controlling intraocular pressure in a patient’s eye is provided. The method includes creating an intraocular entry into the eye, selecting a location along an optical disc of the eye, creating a conduit connecting at least a portion of an intravitreal cavity with at least a portion of a subarachnoid space in the eye at the selected location, deploying at least one stent communicating between the intravitreal cavity and the subarachnoid space via the conduit, and equilibrating the intraocular pressure in the eye by allowing the stent to communicate fluid flow between the intraocular compartment and the subarachnoid space.

  • Publication number: 20230082713
    Abstract: A device for disrupting tissue in an eye including a distal portion sized and configured for ab interno insertion into an anterior chamber of the eye having an elongate, flexible shaft of super-elastic memory-shape material. A distal end region is shaped into a curve having a radially inner surface connected to a radially outer surface by two lateral sides. The device has a tissue disruptor proximal of a distal-most end formed on at least one of the inner surface and the outer surface. The distal face of the tissue disruptor is a blunt tissue-engaging surface without any cutting element. Related methods and devices are provided.

  • Publication number: 20230009442
    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.

  • Publication number: 20220230749
    Abstract: Disclosed herein are methods, devices, and systems for the enhanced monitoring of visual function via telemedicine to detect early onset of changes and abnormalities associated with disease. The systems include a cloud environment or neural network communicating various tests and images to a client device in which a user/patient is properly positioned to view a display of the client device, receive stimuli, and provide patient input which is evaluated in terms of timing and substance to generate a contrast-sensitivity map of a visual function for the patient. Various ocular tests are described for implementation in a new home-based computer environment rather than using expensive and specific medical equipment in a doctor's office.

  • Publication number: 20210407663
    Abstract: A method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use and a device for droplet ejection includes a fluid delivery system capable of delivering a defined volume of the fluid in the form of droplets having properties that afford adequate and repeatable high percentage deposition upon application. The method and device include a housing, a reservoir disposed within the housing for receiving a volume of fluid, an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on the eye of the subject during use.

  • Publication number: 20210353145
    Abstract: Disclosed herein are methods, devices, and systems for monitoring fluid outflow behavior of an eye of a subject, for example, during ocular surgery. Changes to intraocular pressure can reflect fluid outflow behavior. Fluid outflow behavior can be a critical factor in the successful outcome of a surgery and determining likelihood of post-operative side effects. Large fluctuations in intraocular pressure, ocular hypertension, and hypotony can be associated with vision loss or poor ocular health.

  • Publication number: 20210205128
    Abstract: Embodiments of the present specification provide surgical methods and apparatuses to deploy at least one stent through an optic nerve sheath in order to maintain an opening/fenestration for intracranial fluid egress. The surgical method creates a fenestration, an opening, a slit, or a hole, through an optic nerve sheath of a human patient. The fenestration is created in a minimally invasive manner using an applicator, such as an endoscopic visualization apparatus, that includes a stent or shunt for deploying through the fenestration. The presently disclosed specification is indicated to treat papilledema and/or intracranial hypertension and to deliver therapeutic compositions through the optic nerve sheath.
