    摘要： A spray assembly for dispensing a mixture is provided. The spray assembly includes a connector configured for operable engagement with a first and second source of component and a source of pressurized fluid, and a tip operably connected to the connector. The tip includes an opening and defines a mixing chamber between the connector and the opening of the tip, and an insert member configured to be received in the mixing chamber. The insert member includes a plurality of radially extending slots on at least one end of the insert. The plurality of radially extending slots is configured to mix the first and second components prior to the mixture exiting the opening in the tip.

    摘要： In some examples, a device, which may be used to access vasculature or another hollow anatomical structure of a patient, includes a housing, a cannula mechanically coupled to a housing distal end, and a needle configured to be locked in a deployed configuration in which the needle extends within a cannula lumen and protrudes from the cannula distal end. The needle is configured to slide proximally through the cannula lumen from the deployed configuration into a retracted configuration in which at least a portion of the needle is within a housing lumen. The device further includes at least one needle guide configured to maintain the needle along a path in the housing lumen substantially parallel to the needle guide when the needle moves between the deployed configuration and the retracted configuration.
