A system for imploding leukemia cells of a patient includes (a) a first vessel for containing a volume of blood received from the patient, and (b) drive circuitry cooperatively coupled with at least one transducer to produce ultrasound energy that spatially decoheres and disperses throughout the volume, to implode the leukemia cells throughout the volume via absorption of the ultrasound energy by the leukemia cells. The transducer may be an immersible transducer configured to be immersed in the blood. The system may include a second vessel for containing a liquid, within which the ultrasound energy is decohered and dispersed and from which at least a portion of the ultrasound energy is transmitted to the first vessel to implode the leukemia cells.

Disclosed is a device for separating a cellular component from a multicomponent fluid. The device can comprise a body, a first acoustic wave generator, and a second acoustic wave propagating component. The body can define a channel having a first surface and a second surface opposite the first surface. The channel can extend along a longitudinal axis from a first end to a second end. The first acoustic wave generator can be coupled to the first surface. The first acoustic wave generator can be configured to generate an acoustic wave having a wavelength. The second acoustic wave propagating component can be coupled to the second surface. The second surface can be spaced an integer fractional multiple of the wavelength from the first surface and each integer factional multiple equals a number of pressure nodes within the channel.

A microwave therapy apparatus and method for blood cancer treatment is disclosed. The microwave therapy apparatus for blood cancer treatment includes a plurality of porous anodic aluminum oxide (AAO) filters or a plurality of porous glass filters provided in a dialyzer of a hemodialysis apparatus; a nanoflower filter provided downstream of the plurality of porous anodic aluminum oxide (AAO) filters or the plurality of porous glass filters in the blood tube; and an RF absorber provided downstream of the nanoflower filter to attract cancer cells thereto by generating a frequency of a predetermined band, wherein the blood, from which the cancer cells have been removed by an RF frequency and which includes normal blood cells that passed through the nanoflower filter, is circulated and supplied to a blood tube connected to a vein of the body of the blood cancer patient.

An RF driver provides power to an acoustic transducer, which can be implemented as a piezoelectric element, which presents a reactive load. The driver can be a linear amplifier or a combination of a DC-DC converter and DC-AC inverter. A controller implements a control technique for efficient transducer operation. The control technique can locate a frequency for operation that is at a reactance minimum or maximum for the transducer to provide efficient operation of that transducer. An implementation of the controller can be provided in modular hardware.

The present disclosure describes a system and method for microfluidic separation. More particularly, the disclosure describes a system and method for the purification of a fluid by the removal of undesired particles. The device includes microfluidic separation channels that include multiple outlets. The device also includes isolation slots positioned between each of the microfluidic separation channels. The device's base includes multiple acoustic transducers which in some implementations are configured to protrude into the isolation slots. The acoustic transducers are configured to generate aggregation axes within the separation channels, which are used to separate out undesired particles.

A method and system for detecting and neutralizing blood clots during dialysis (e.g., hemodialysis) is provided. A fiber-optic sensor is provided in a hemodialysis machine to detect vibration of blood cells, and the hemodialysis machine can be configured to prevent blood clotting by sounding an alarm, agitating the blood cells, infusing saline, raising temperature and/or infusing heparin.

An operational unit for locating and neutralizing pathogen cells in blood. A cassette has a plurality of thin holding chambers that are filled with blood drawn from a patient. A light source illuminates each of the holding chambers and passes light to an underlying sensor array such that the cells in the blood produce shadow images of the cells in the sensor array. A processor performs pattern recognition to identify and locate the pathogen cells by use of an image library. After the pathogen cells are located, the pump is operated to move the identified cells to a processing zone. When each identified cell reaches the processing zone, electric energy is applied to destroy the identified pathogen cells. A pump refills the cassette holding chambers, returns the neutralized-pathogen blood to the patient, and the process is repeated for a treatment time period.
