20230113341 · 2023-04-13 ·

A method of predicting the outcome of a hospitalized acute brain injury patient is provided. The method includes using a pupilometer to take paired pupillary measurements of a left and right eye of the patient; using the pupilometer to determine NPI of the left eye and display it on a display of the pupillometer; using the pupillometer to determine NPI of the right eye and display it on the display of the pupillometer; calculating a differential between NPI of the left eye and NPI of the right eye and display said NPI differential on the display of the pupillometer; and predicting an unfavorable health or neurological outcome if the NPIs of the left and right eyes indicate normal pupillary responses for each eye but the NPI differential meets or exceeds a given threshold value.

Programmable therapeutic agent delivery from eye mounted device

The present disclosure relates to relates to systems and methods for on-demand delivery of a therapeutic agent from an eye mounted device. Particularly, aspects of the present invention are directed to a method of delivering a therapeutic agent, the method including receiving, at a controller of a therapeutic agent release and delivery device, a first command signal for delivery of a therapeutic agent based on a dosing time window. Upon receipt of the first command signal, the controller determines whether one or more compliance conditions are satisfied. When the one or more conditions are satisfied, the controller initiate a release and delivery protocol that commands a signal generator to generate and send a second command signal causing a capacitor or one or more circuits to deliver an actuation signal causing one or more therapeutic agent delivery mechanisms to open and release the therapeutic agent from one or more reservoirs.

Intracardiac sensors with switchable configurations and associated systems and methods

The present technology relates to intracardiac sensors and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include an implantable capacitor having a capacitance value that is variable based on the pressure within the patients heart and a sensing circuit configured to measure the capacitance value. The device can also include an implantable inductor and a power circuit configured to wirelessly receive power from an external source via the inductor. When the device is in a first configuration, the capacitor can be electrically coupled to the sensing circuit and the inductor can be electrically coupled to the power circuit. When the device is in a second configuration, the capacitor can be electrically coupled to the inductor to form a resonant circuit.

Surgical foot pedal device having force feedback
11617682 · 2023-04-04 · ·

A foot pedal device configured to provide force feedback to an operator during ophthalmic surgery is described. The foot pedal device includes a processor and a memory containing instructions which, when executed by the processor, cause the processor to transmit, in response to a movement of a moveable member, a control signal to a surgical console for initiating an action of an ophthalmic surgery tool coupled with the surgical console. The foot pedal device includes a force feedback mechanism configured to selectively apply a resistance force in opposition to the movement of the movable member. The memory contains instructions which, when executed by the processor, cause the processor to receive, from the surgical console, a trigger signal, and send a force feedback signal to the force feedback mechanism. The force feedback mechanism is configured to apply the resistance force to the movable member upon receiving the force feedback signal.
