Abstract: Described herein are systems, devices, and methods for methods for filtering fluids received from a patient. In embodiments, an apparatus can include a fluid conduit configured to receive a volume of fluid from a patient, the volume of fluid including a plurality of particulates having different sizes; a container including an inlet near a first end and an outlet near a second end opposite the first end, the inlet being fluidically coupled to the fluid conduit, the container defining a reservoir configured to receive the volume of fluid from the fluid conduit via the inlet; first and second filters; and an outlet being couplable to a vacuum source that can generate negative pressure to draw at least a portion of the volume of fluid within the reservoir through the second filter and into the vacuum source.

Abstract: Described herein are systems, devices, and methods for methods for autologous blood transfusion. For example, an apparatus may comprise a fluid conduit configured to receive a volume of fluid from a patient and a container fluidically coupled to the fluid conduit. The container may define a reservoir configured to receive the volume of fluid from the fluid conduit. The apparatus may include a vacuum conduit couplable to a vacuum source, a vent configured to vent air into the reservoir, and at least one valve configured to couple the reservoir to the vacuum conduit to generate negative pressure within the reservoir such that the volume of fluid is drawn into the reservoir, and decouple the reservoir from the vacuum conduit while coupling the reservoir to the vent such that air is vented into the reservoir at an average rate that prevents turbulent movement of the volume of fluid within the reservoir.

Abstract: Described herein are systems, devices, and methods for aspiration and mechanical thrombectomy. In some embodiments, a thrombectomy device for removing a thrombus from a vessel can include a handle assembly, a vacuum source, an aspiration catheter with an expandable distal portion, and a flexible shaft configured to rotate within the aspiration catheter.

Abstract: Described herein are systems, devices, and methods for removing material from patient vasculature. In some embodiments, an aspiration device may include a sheath and a catheter slidably disposed within the sheath and defining a lumen. The catheter may include a distal end portion and an elongate portion, the distal end portion being disposable adjacent to a clot, the elongate portion being couplable to a vacuum source that is configured to apply a negative pressure to the lumen to draw the clot into the distal end portion. The distal end portion may include a plurality of sections, each of the plurality of sections having a different cut pattern.
