  • Patent number: 12582551
    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.

  • Patent number: 12558259
    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: 12310892
    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.
