The present invention provides a device and a method for separating particles from fluids using ultrasound, laminar flow, and stationary wave effects comprising a micro-technology channel system with an integrated branching point or branching fork, and a single ultrasound source. One of the characteristics of the invention is that the single ultrasound source, which generates the standing waves, excites the complete structure including the channel system. No special reflectors or the like are needed. Extremely thin dividers can separate the flow, thereby enhancing the effectiveness of the device. The device could be manufactured in silicon and the ultrasound energy could preferably be delivered by a piezoelectric element.

Device and method for separation

A perfusion system for non-surgically isolating and perfusing an organ, particularly the liver (,), in a patient, and including; by-pass cathether apparatus having inlet and outlet lumens (,) introducible into the blood vessels of the organ percutaneously and devised so as to by-pass the blood flow past the organ in a by-pass circuit; perfusion catheter apparatus having inlet and outlet lumens (,) introducible into the blood vessels percutaneously and being devised so as to lead the flow of perfusion fluid in a perfusion circuit through the organ; occlusive seals (,) for isolating the organ from the systemic blood flow; pump apparatus including a by-pass pump (,), a perfusion fluid pump (,) and a suction pump (,) for establishing a negative relative pressure at the perfusion outlet from the organ; and control apparatus (,) coupled to the pumps (,) so as to control the operation thereof such that the outflow of fluid from the organ exceeds the inflow of fluid into the organ in the perfusion circuit due to a net volume contribution of blood from the systemic circulation entering the isolated organ.
