Patents by Inventor David Y. Badawi

David Y. Badawi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220280339
    Abstract: Described here are systems and methods for accessing Schlemm's canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm's canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

  • Patent number: 11389328
    Abstract: Devices, methods and kits are described for reducing intraocular pressure. The devices include a support that is implantable within Schlemm's canal and maintains the patency of the canal without substantially interfering with transmural fluid flow across the canal. The devices utilize the natural drainage process of the eye and can be implanted with minimal trauma to the eye. Kits include a support and an introducer for implanting the support within Schlemm's canal. Methods include implanting a support within Schlemm's canal, wherein the support is capable of maintaining the patency of the canal without substantial interference with transmural fluid flow across the canal.

  • Publication number: 20220168146
    Abstract: Devices, methods and kits are described for reducing intraocular pressure. The devices include a support that is implantable within Schlemm's canal and that may restore or maintain at least partial patency of the canal without substantially interfering with transmural or transluminal fluid flow across the canal. The devices utilize the natural drainage process of the eye and may be implanted with minimal trauma to the eye. Kits may include a support and an introducer for implanting the support within Schlemm's canal. Methods may include implanting a support within Schlemm's canal, where the support is capable of restoring or maintaining at least partial patency of the canal without substantial interference with transmural or transluminal fluid flow across the canal.
