Patent number: 12042428Abstract: 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.Type: GrantFiled: April 3, 2023Date of Patent: July 23, 2024Assignee: SIGHT SCIENCES, INC.Inventors: David Y.

Patent number: 11877954Abstract: Provided herein are methods and devices for grasping and/or tearing trabecular meshwork of an eye of a subject. The devices may include a shaft and a tissue grabber coupled to the shaft. The tissue grabber may include an elongate lower foot configured to be inserted into Schlemm's canal, and a groove configured to grasp a portion of the trabecular meshwork. The methods may include: advancing a tissue grabber to Schlemm's canal of the eye, wherein the tissue gripper comprises a lower foot and a tissue grabbing region; advancing a tip of the lower foot through the trabecular meshwork and into Schlemm's canal; and advancing the lower foot within and relative to Schlemm's canal, wherein as the lower foot is advanced, a portion of the trabecular enters the tissue gripping region, is torn from surrounding tissue, and is collected within the tissue gripping region.Type: GrantFiled: March 15, 2023Date of Patent: January 23, 2024Assignee: SIGHT SCIENCES, INC.Inventors: David Y.

Publication number: 20220168136Abstract: Controllers for dry eye treatment apparatus and methods are described herein which generally comprise a patch or strip affixed to the skin of the upper and/or lower eyelids to deliver heat to the one or more meibomian glands contained within the underlying skin. The treatment strip or strips include one or more strips configured to adhere to an underlying region of skin in proximity to one or both eyes of a subject such that the one or more strips allow for the subject to blink naturally without restriction from the one or more patches. A controller is in communication with the one or more strips and is programmable to monitor a temperature of the one or more strips to provide a treatment therapy above a threshold temperature. Additionally forceps for mechanically expressing the Meibomian glands may be included with the strips and/or controller.Type: ApplicationFiled: February 16, 2022Publication date: June 2, 2022Applicant: Sight Sciences, Inc.Inventors: Paul BADAWI, David BADAWI, Scott HARSHMAN, Daniel O'KEEFFE
