Abstract
A method of causing an object to act as a cavitation nucleus comprising the steps of providing a sound energy source capable of generating a sound energy over a plurality of frequency ranges, providing a target object contained in a liquid, coupling the sound energy source to the liquid, determining a specific frequency range, within the frequency ranges, that resonates the target object, and exposing the target object to sound energy at the specific frequency range to cause the target object to act as a cavitation nucleus.

A method of causing an object to act as a cavitation nucleus comprising the steps of:
- providing a sound energy source capable of generating a sound energy over a plurality of frequency ranges;
- providing a target object contained in a liquid;
- coupling said sound energy source to said liquid;
- determining a specific frequency range within said frequency ranges that resonate said target object;
- and
- exposing said target object to sound energy at said specific frequency range to cause said target object to act as a cavitation nucleus.
A method of causing a cell to act as a cavitation nucleus comprising the steps of:
- providing a sound energy source capable of generating a sound energy over a plurality of frequency ranges;
- providing multiple test sets of cells in a liquid;
- exposing each test set of cells to sound energy at a different frequency range;
- determining an inactivation efficiency for each test set;
- determining an optimal frequency range out of said frequency ranges which has the highest inactivation efficiency;
- providing a target cell contained in a liquid;
- exposing said target cell in said liquid to sound energy at said optimal frequency range to cause said target cell to act as a cavitation nucleus;
- whereby said target cell is inactivated.
An apparatus for destroying cancer cells in blood comprising:
- a first catheter for receiving a blood flow from a body;
- a blood pump;
- a vessel through which said blood flow passes and having a sound energy source, said sound energy source configured and arranged to generate sound energy having a frequency range that causes said cancer cells to become cavitation nuclei;
- and
- a second catheter for returning said blood flow to said body.
