Abstract: Devices, systems, and methods used to dress a catheter device are disclosed. The devices and systems include a catheter dressing system including a body, a closure member, an adhesive plate, and an extension tubing having a catheter connector coupled to a distal end. The catheter dressing system is displaceable over the extension tubing and the extension tubing passes through the closure member. The catheter connector is disposable within a chamber of the body to prevent movement of the catheter connector. The closure member is actuated to form a circumferential seal around the extension tubing to prevent contamination of the catheter connector and to prevent axial movement of the extension tubing. The adhesive plate can be adhered to a patient's skin to form a circumferential seal around a catheter skin puncture site. The method includes sliding the catheter dressing system along the extension tubing.

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: A coordinated cutting and spreading mechanism within a syringe dilator sub-assembly is applied to an eye surface during an intravitreal injection to provide an access window free of the conjunctival layer and through which an injection needle can be inserted. The system and method comprises a dilator sub-assembly including both the cutting and spreading mechanism and the intravitreal injection needle, for use with a conventional syringe. The dilator sub-assembly includes a number of projections to secure points of the surface of the conjunctival layer, a cutting member to incise the conjunctival layer, and at least one deflectable projection to move during the intravitreal injection, spreading the incision, and creating a window opening in the conjunctival layer through which the intravitreal injection needle then enters. Upon removal of the device from the injection site, the deflectable projection is released and the window opening in the conjunctival layer is closed.
