Abstract: An apparatus for removing air from a fluid comprises a vertically oriented chamber having top and bottom chamber portions separated by a chamber sidewall at least partially defining a chamber interior having a chamber centerline. A fluid inlet provided through the chamber sidewall selectively permits ingress of fluid to the chamber interior. Fluid entering the chamber interior through the fluid inlet is directed laterally between the chamber sidewall and the chamber centerline. A fluid outlet located proximate the bottom chamber portion selectively permits egress of fluid from the chamber interior. An air release structure located proximate the top chamber portion selectively releases accumulated air from the chamber interior. Fluid entering the chamber interior through the fluid inlet achieves a vortex motion during travel downward to the fluid outlet. The vortex motion prompts release of air from the fluid, the air collecting adjacent the air release structure for selective release.

Abstract: A multipurpose tissue sampling device is provided for extracting at least one tissue sample from a tissue sampling site. An outer sheath has a cutting surface and an outer sheath lumen extending from an outer sheath proximal end to an outer sheath distal end. An inner stylet has a solid inner stylet cutting tip, sampling notch, and an inner stylet lumen extending from an inner stylet proximal end to the sampling notch. The inner stylet exterior wall is configured to pass through the outer sheath lumen. A fine needle aspiration needle has an FNA needle body configured to pass through the inner stylet lumen. The FNA needle has an FNA needle lumen and a sampling feature. An actuator has a proximal port and a distal port with inner port walls that are configured to accept at least a portion of at least one of the outer sheath and inner stylet.
