    摘要： A phlebotomy device includes a needle defining a lumen and having a proximal end portion and a distal end portion. The distal end portion includes a sharpened tip configured to pierce tissue. The phlebotomy device further includes a sensor disposed at least partially within the lumen. The sensor has a first state and a second state and is configured to transition from the first state to the second state upon exposure to blood at physiological temperature.

    摘要： Positive displacement fluid lock ports for use in combination with an indwelling catheter and a syringe during a flushing/locking procedure are provided. The fluid lock port includes a housing having a distal and a proximal end; a resilient conduit supported within the housing, wherein the conduit defines a lumen therethrough; and at least one biasing member supported in the housing and being operatively associatable with the resilient conduit. The at least one biasing member has a first condition restrained from deforming the resilient conduit and a second condition operatively engaged with the resilient conduit to at least partially occlude the lumen of the resilient conduit.

    摘要： A thermal treatment device for forming a micropore in a barrier has a micro-heater component with at least one micro-heater with a thermal member having a base end and a tip end. The device also has an ablation material in the at least one micro-heater and a power supply component for activating the micro-heater component. The ablation material expands in response to the activation in order to mechanically puncture the barrier to a first depth without thermally inducing ablation of the barrier and the micro-heater component enlarges the first depth of the micropore to a second depth and/or produces an improvement in at least one physiological property of the micropore.
