  • Patent number: 11944703
    Abstract: An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the suprachoroidal space (SCS). The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

  • Publication number: 20220079878
    Abstract: The present invention provides a composition for treatment of ophthalmic disease comprising a solid or semi-solid containing drug shaped as an elongated body for injection or delivery into tissue spaces of the eye. The composition may comprise a plurality of drug-containing particles and at least one excipient to form the drug particles into a flexible solid or a semisolid. The excipient comprises a substance that undergoes dissolution in the physiological conditions of the tissue space after injection to allow the microspheres to disperse and migrate in the tissue space. Formulations for the drug containing compositions, methods of fabrication and methods of use are also disclosed.

  • Publication number: 20220062041
    Abstract: The present invention provides devices to access the suprachoroidal space or sub-retinal space in an eye via a minimally invasive transconjunctival approach. The devices may also be used after a partial dissection, for example after dissection of the outer scleral layer of the eye, and using the device within the dissection to access the suprachoroidal space or the sub-retinal space.

  • Patent number: 11154420
    Abstract: A device for controlled delivery of an injection material to tissue spaces of an eye that are not normally open, such as the subconjunctival space, the suprachoroidal space and the subretinal space. The device comprises an elongated body with a hollow cannula at the distal end, a slidable plunger at the proximal end, and a reservoir for the material to be injected residing between the cannula and the plunger. The plunger is mechanically coupled to a source of force such as a spring or pressurized gas reservoir such that an injection force is applied to the injection material within the device prior to delivery of the injection material into an eye. A valve that is normally closed to prevent flow of the injection material during application of the injection force is placed in the flow path between the cannula and reservoir. Due to the injection force placed on the injection material, actuation of the valve allows controlled flow from the reservoir through the cannula and into the tissue space.

  • Patent number: 11096822
    Abstract: Injection device comprising an elongated body (1) with a hollow needle (8) at a distal end; a reservoir for an injection material to be delivered through the needle; a plunger (3) with a first force element (5) configured to provide an injection force to said injection material, and a distal element (10) attached to the distal end of the device thereby sealing a needle lumen, wherein the distal element comprises a tissue interface and a distal seal (11), and wherein the distal seal is penetrable by a distal tip of the needle by the application of pressure on a tissue surface with the distal end of the device, wherein the penetrated distal element becomes slidable on the needle to allow advancement of the needle into tissue, wherein the penetrated distal seal opens a path for flow or delivery of the injection material from the distal end of the needle.

  • Publication number: 20210212940
    Abstract: Drug formulations, devices and methods are provided to deliver biologically active substances to the eye. The formulations are delivered into scleral tissues adjacent to or into the suprachoroidal space without damage to the underlying choroid. One class of formulations is provided wherein the formulation is localized in the suprachoroidal space near the region into which it is administered. Another class of formulations is provided wherein the formulation can migrate to another region of the suprachoroidal space, thus allowing an injection in the anterior region of the eye in order to treat the posterior region.
