  • Patent number: 12589024
    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.

  • Publication number: 20260079596
    Abstract: An apparatus includes circuitry to detect a crossing between an in-phase drive signal, received over a first analog line, and an opposite-phase drive signal, received over a second analog line of a touch panel. Multi-phase switching asserts an output in response to both detecting the crossing and receiving a signal indicative of a phase switch between the in-phase drive signal and the opposite-phase drive signal. The output controls timing of applying a multi-phase switching pattern to sets of switches coupled between the first and the second analog lines and respective ones of transmission (TX) electrodes of the touch panel.

  • Publication number: 20260026971
    Abstract: 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.

  • Publication number: 20250332028
    Abstract: Described here are systems and methods for accessing Schlemm's canal and for delivering an ocular device, tool, 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. Some systems described here may be configured to cut or tear the trabecular meshwork with the body of an elongate member located within Schlemm's canal. Other 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: 12425026
    Abstract: Front-end circuits that combine inductive and capacitive sensing are described. In one embodiment, an apparatus includes a plurality of inductive elements, an inductive measurement circuit, and a frequency divider circuit. The inductive measurement circuit is to output a first signal with a first frequency. The first signal is associated with an inductance change of one of the inductive elements. A feedback circuit can maintain the sinusoidal operation of the first signal. The frequency divider circuit can generate a second signal with a second frequency that is lower than the first frequency.

  • Patent number: 12416995
    Abstract: An apparatus includes a sinusoidal wave generator that generates, over a first analog line, an in-phase drive signal and, over a second analog line, an opposite-phase drive signal. A comparator has inputs respectively coupled to the first analog line and the second analog line and asserts a first output in response to detecting a crossing between the in-phase drive signal and the opposite-phase drive signal. Multi-phase switching logic is coupled to an output of the comparator. The multi-phase switching logic asserts a second output in response to both detecting the first output and receiving a signal indicative of a phase switch of the sinusoidal wave generator. The second output controls timing of applying a multi-phase switching pattern to sets of switches coupled between the first analog line and the second analog line and transmission (TX) electrodes of a touch panel.

  • Publication number: 20250268752
    Abstract: Disclosed herein are systems, devices, kits, and associated methods for treating conditions of the eye by reducing intraocular pressure. The system may include an ocular implant and a delivery device. The ocular implant may be implantable within Schlemm's canal to restore or maintain at least partial patency of the canal without substantially interfering with transmural or transluminal fluid flow across the canal. The delivery device may include a cannula comprising a straight proximal portion and a curved distal portion, where the curved distal portion comprises a first curve in a first direction. The delivery device may also include a positioning tool positioned at least partially within the cannula and configured to advance the ocular implant through the cannula, where the positioning tool comprises a curved distal portion biased to form a second curve in a second, different direction.

  • Patent number: 12257181
    Abstract: 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 of, e.g., 39° C., and below a maximum temperature of, e.g., 48° C., over a treatment period of 12 minutes.
