Abstract: Electrolytic gas generator and multi-functional current collector for use in same. In one embodiment, the current collector is constructed both to conduct current from an electrode to a conductive lead and to conduct gas generated at the electrode to external tubing. Accordingly, the current collector may be formed by bonding together a top metal plate and a bottom metal plate of similar profiles, each of which may be shaped to include a main portion and a lateral extension. The bottom metal plate may have central through hole in the main portion for receiving gas from the anode. The top metal plate may have a recess on its bottom surface. The recess may have a first end aligned with the through hole on the bottom metal plate and may have a second end at the end of the lateral extension. A lead and tubing may be attached to the lateral extension.

Abstract: Wearable system and method for gas delivery to the exterior surface of an eye. In one embodiment, the system may include a gas source and a wearable gas delivery device. The gas source may include a housing, one or more electrochemical gas generating devices positioned within the housing, and a control unit for controlling the operation of the one or more electrochemical gas generating devices. The one or more electrochemical gas generating devices may include an electrochemical oxygen concentrator and a water electrolyzer. Oxygen outputted from the electrochemical oxygen concentrator may be combined with oxygen and/or hydrogen outputted from the electrolyzer to produce a therapeutic gas having an enriched oxygen concentration and a hydrogen concentration less than 4%. The wearable gas delivery device, which is fluidly coupled to the gas source, may be worn over the eye and may be used to deliver the therapeutic gas to the eye.

Abstract: System and method for modification of fluid environment of an ear. In one embodiment, the system includes an earpiece mountable within an ear canal. The earpiece includes a fluid delivery path for fluid to be delivered to the ear and a fluid removal path for fluid to be removed from the ear. The system also includes an electronics housing. The electronics housing may be directly mounted on the earpiece or positioned outside the ear. The system further includes an electrochemical gas generating device positioned within the electronics housing. In use, oxygen or the like is generated by the electrochemical gas generating device and is conveyed through the fluid delivery path of the earpiece, emerging from the earpiece distal end. The gas released from the earpiece causes fluid in the ear to be swept into the fluid removal path of the earpiece and eventually expelled to the outside of the ear.
