  • 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: 20220409560
    Abstract: The present invention provides a method for the treatment of retinoblastoma comprising administering a composition comprising a therapeutically active agent to a subject in need thereof by injection of the composition into the vitreous cavity, suprachoroidal space, supraciliary space or sub-Tenon's space of the eye adjacent to a retinoblastoma tumour. The invention also provides a composition comprising at least one therapeutically active agent selected from the group consisting of a Bcl-2 inhibitor or a topoisomerase inhibitor for use in the treatment of retinoblastoma, wherein the composition is for administration into the vitreous cavity, suprachoroidal space, sub-Tenon's space, or supraciliary space adjacent to a retinoblastoma tumour in an eye. Also provided is a kit comprising a Bcl-2 inhibitor and a topoisomerase inhibitor for use in the treatment of retinoblastoma, wherein the Bcl-2 inhibitor and the topoisomerase inhibitor are for separate, simultaneous or sequential administration.

  • 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.

  • Publication number: 20150265434
    Abstract: A flexible distal cup for use as part of a modular prosthetic socket for a residual limb may have a substantially closed distal end, an open proximal end, an inner surface and an outer surface. The flexible distal cup is configured to reside within an outer support structure of the prosthetic socket and to receive a distal portion of the residual limb. In some embodiments, the flexible distal cup may be made of a composite polymer composition, including an ethylene-vinyl acetate (EVA) copolymer and polycaprolactone (PCL). The EVA copolymer may be between about 45% and about 55% of the composite polymer composition by weight, the vinyl acetate of the EVA copolymer may be less than about 25% of the EVA copolymer by weight, and the PCL may be between about 45% and about 55% of the composite polymer composition by weight.
