  • Publication number: 20210196516
    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.

  • Patent number: 11011270
    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.

  • Patent number: 10912673
    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.

  • Patent number: 10905591
    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: 20200337896
    Abstract: The present disclosure provides methods and devices which improve upon prior art methods and devices for delivering atropine to the eye. In certain aspects, the disclosure provides method for delivering a composition comprising atropine to an eye of a subject in need thereof as a micro-dose stream of droplets. The method generally includes, (a) generating a micro-dose stream of droplets including the composition comprising atropine via a piezoelectric droplet delivery device, wherein the micro-dose stream of droplets has an average ejected droplet diameter greater than 15 microns; and (b) delivering the micro-dose stream of droplets to the eye of said subject. In certain embodiments, the method treats myopia, in particular progressive myopia (nearsightedness) in adults and children, in the subject in need thereof.

  • Publication number: 20200187601
    Abstract: Systems, methods, and computer-readable storage media for applying an adhesive film to the sole of shoes. Application of a portion of the adhesive film can be performed by receiving a shoe on top of the adhesive film, which in turn is above a plate and compressible pins. Upon receiving the shoe, the plate is raised or lowered, and the compressible pins mark the perimeter of the sole of the shoe. The adhesive film is cut in a sole-shaped pattern due to the height differentiation, resulting in a sole-shaped portion of the adhesive film being adhered to the sole of the shoe.

  • Patent number: 10085633
    Abstract: A direct visualization (DV) system and methods are disclosed for measuring one or more anatomical features of the eye, including a depth of the iridocorneal angle of the eye. The DV system can include a wire extending distally from a handle with the wire having one or more indicators for measuring anatomical features of the eye. The DV system can be deployed into the eye and used with minimal trauma to ocular tissues. Furthermore, the DV system can be used independently or alongside other ocular instruments, such as instruments having indicators corresponding to the DV system for correctly implanting ocular implants without the use of a gonio lens.
