Injector, in particular dual function injector and/or injector with stop element
11684470 · 2023-06-27 · ·

An injector for ejecting an intraocular lens for injecting the latter into an eye or for implanting a corneal endothelial tissue, including an elongate injector body which has a piston rod passage and in which an injector piston rod having a screw thread is guided in a longitudinally displaceable manner. The injector is provided with two operating modes for the displacement of the injector piston rod and is able to be switched between the modes. The first operating mode defines an ejection operation and the second operating mode defines a screwing operation. The injector body has at least one retractable and deployable wing grip, wherein the operating mode is set to ejection operation by the deployed position and the operating mode is set to screwing operation by the retracted position. The injector piston rod includes a stop element.

OPHTHALMIC LENS INSERTER APPARATUS AND METHOD

An embodiment in accordance with the present invention provides an apparatus and method for inserting a lens into pocket in the cornea. The apparatus includes a handle, a plunger extending movably through the lumen of the handle, and a first and a second actuators. In particular the plunger includes a distal segment which extends beyond the distal end of the handle and the first and second actuators are coupled to the plunger configured in such a way to provide different ranges of motion and synchronized movement of a bottom, middle, and top tines of the plunger for improved and safer lens insertion into the corneal pocket.

Corneal implant injector system

A corneal implant injector system includes an injector including a plunger slidable in a plunger housing, and a distal cartridge grabbing member engageable with an implant-holding cartridge.

DEVICE FOR SUPPORTING AND TRANSPORTING A GRAFT OR IMPLANT
20170340428 · 2017-11-30 ·

The aim of the invention is to ensure a secure support and/or a secure transport of a graft (4) or an implant. This is achieved by a device for supporting and transporting a graft (4) or implant, comprising a container (2) which can be filled with a medium (1), preferably a nutrient medium, and a receiving device (3) which can be arranged in the container (2) for the graft (4) or implant. The receiving device (3) has a receiving chamber (5) for the graft (4) or implant and two passages (6, 7) which lead to the receiving chamber (5), at least one of said passages (6, 7) being dimensioned for introducing and/or removing the graft (4) or implant into or out of the receiving chamber (5). The device also comprises a respective closure device (8, 9) for each of the two passages (6, 7), at least one of the closure devices (8, 9) being permeable for the medium (1). The invention further relates to a corresponding receiving device (3) and to a set comprising a corresponding device.

Molding or 3-D printing of a synthetic refractive corneal lenslet
11259914 · 2022-03-01 ·

A method of forming and implanting a synthetic corneal lenslet in an eye of a patient includes the steps of: forming a synthetic lenslet from a collagen solution using a mold or a 3-D printer that are configured to form the synthetic lenslet into a predetermined shape for correcting a particular refractive error of the patient; forming a cavity for receiving the synthetic lenslet in the cornea of the eye of the patient; inserting the synthetic lenslet into the cavity of the eye; applying a photosensitizer into the cavity of the eye so that the photosensitizer permeates at least a portion of the tissue surrounding the cavity and at least a portion of the synthetic lenslet; and irradiating the cornea so as to activate cross-linkers in the synthetic lenslet and cross-linkers in the portion of the tissue surrounding the cavity, and thereby prevent an immune response.

Implant delivery devices, systems, and methods

Systems, devices, and methods for delivering an implant to the orbit. In some instances, the systems may include a delivery device having a tongue member and a handle. The delivery device may further include an ejector configured to deliver an implant from the tongue member. The delivery device may also include a piercing member configured to create an opening in tissue. The systems may further include a piercing member for creating an opening in tissue. In some instances, the piercing member may have a first blade member rotatably connected to a second blade member.

COSMETIC CORNEAL INLAY AND IMPLANTATION METHOD THEREOF
20170319330 · 2017-11-09 ·

Disclosed is an intrastromal insert, already preformed, of solid, transparent, impermeable, biocompatible, physiologically inert and chemically resistant material, with notches allowing the passage of metabolites, substances, cells or portions thereof, and drugs, configured to receive printing, which is adapted in the space of the corneal stroma to change the eye color and/or to solve the problem of insufficient pigmentation of the iris. The method and the related component to change, permanently and reversibly, the eye color for aesthetic purposes are described as well.

Therapeutic instrument and attachment thereof

There is provided a therapeutic instrument, for storing a sheet-type therapeutic substance to which a liquid is delivered, and delivering the stored therapeutic substance to an affected part, including: a nozzle member 23 having an opening 34 on a tip end of a tubular part 31 in which the therapeutic substance can be stored, for charging and discharging the therapeutic substance; and a syringe unit 22 that selectively causes a negative pressure and a positive pressure to act in the tubular part 31 through a hole of a valve member 27, wherein the space 33 of the tubular part 31 is the space for sucking the therapeutic substance into the tubular part 31 together with the liquid by causing the negative pressure in the tubular part 31 by the syringe unit 22 when the therapeutic substance is stored therein, and is the space for pushing out the therapeutic substance to outside of the tubular part 31 together with the liquid by causing the positive pressure to act in the tubular part 31 by the syringe unit 22 when the stored therapeutic substance is delivered to the affected part.

GAS CANISTERS AND METHODS FOR MAKING THEM

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.
