  • Patent number: 12343288
    Abstract: Systems and methods for delivering multiple ocular implants to reduce intraocular pressure are disclosed. The ocular implants can be implanted at multiple sites within a single human eye without requiring removal of the delivery apparatus from the eye. A system for delivering multiple ocular implants can include at least two implants preloaded within a delivery device and configured to be implanted within the eye, a metering device configured to transfer energy to the implants for delivery at selected locations within the eye, wherein the metering device is configured to meter a variable amount of energy for each implant delivery event in the eye. The system can further include an injector mechanism configured to serially engage and drive each of the implants.

  • Publication number: 20210361477
    Abstract: A cannula adapter guiding a catheter out of a cannula and dispensing fluid from a reservoir is disclosed. The cannula adapter includes a first slidable member operably connected to the catheter such that a distal movement of the first slidable member causes the catheter to move within and out of the cannula. The cannula adapter includes a second slidable member operably connected to a plunger and the reservoir such that a proximal movement and a subsequent distal movement of the second slidable member dispenses fluid from the reservoir and out from the catheter.

  • Publication number: 20210154449
    Abstract: Systems and methods for treating ocular disorders are disclosed. One system has a delivery instrument, with a non-linear axis, configured to be inserted into an anterior chamber of an eye and moved to a location proximate a physiologic outflow pathway of the eye. The delivery instrument carries an implant that has a distal end sized for insertion into tissue such that aqueous humor drains from the anterior chamber to the physiologic outflow pathway. One method involves inserting a non-linear portion of a delivery device into the anterior chamber to position an implant within the eye. Another method involves using a delivery device with a curved distal portion to implant an implant at a location communicating with the physiologic outflow pathway. The delivery can be through a corneal incision and the implant can comprise a drug.

  • Publication number: 20200155349
    Abstract: Intraocular stents and applicators are disclosed for treating glaucoma. The stents are configured to extend between the anterior chamber of the eye and Schlemm's canal for enhancing outflow of aqueous from the anterior chamber so as to reduce intraocular pressure. The stents can have features for anchoring the stent into Schlemm's canal as well as preventing the walls of Schlemm's canal from closing the outlet of the stents. The applicators can be steerable so as to make implantation easier. Additionally, the applicators can be configured to hold a plurality of stents so that multiple stents can be implanted through one incision without removing the applicator from the incision between serial implantations.

  • Publication number: 20190321225
    Abstract: A method is provided for treatment of cataract in combination with a glaucoma procedure while maintaining the intraocular pressure by permitting aqueous to flow out of an anterior chamber of the eye through a surgically stented pathway. A trabecular stent is adapted for implantation within the trabecular meshwork of an eye such that intraocular liquid flows controllably from the anterior chamber of the eye to Schlemm's canal, bypassing the trabecular meshwork. Depending upon the specific treatment contemplated, pharmaceuticals may be utilized in conjunction with the trabecular stent enabling post-cataract healing processes.

  • Patent number: 10406029
    Abstract: Ocular implants, delivery devices and methods for treating ocular disorders are disclosed. One method involves inserting an implant on one side of an eye. The implant has an anchor on a distal end portion and an outlet opening that is disposed proximal of the anchor. The implant is advanced across the eye to the other side of the eye. The anchor is inserted into eye tissue on the other side of the eye. A therapeutic agent is eluted using the implant.

  • Patent number: 10285856
    Abstract: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
