Abstract
Devices, systems, and methods manipulate target materials within fluids, and may be useful for removing microbubbles and other materials from blood. Ultrasound or acoustic filtering waves may be directed across a flow of blood, and differences in density between the target microbubbles and the blood may enhance separation by driving the lighter matter upward for removal from the blood stream. A disposable acoustically transmissive conduit can replaceably engage an ultrasound transmitter to facilitate sterilization. Exemplary conduits have elongate lumen cross-sections and an axial path resembling a portion of a Mobius strip.
Claims16
A filter for separating a target matter from a fluid flow, the filter comprising:
- a fluid conduit having an input for receiving the fluid flow, an output, and a lumen defining a fluid flow path from the input to the output;
- an ultrasound or acoustic transmitter for transmitting ultrasound or acoustic waves;
- and
- a target matter port in fluid communication with the conduit lumen, the transmitter oriented so that the waves drive the target matter across the fluid flow path toward the port.
