Zusammenfassung:A surgical treatment apparatus comprises a waterjet configured to fragment tissue and provide intact cells such as stem cells with the fragmented tissue. The intact cells can be used in one or more of many ways such as for genetic or other testing. In many embodiments, the intact cells comprise stem cells. In many embodiments, a waterjet is configured to fragment tissue. The fragmented tissue can be collected with a filter having pores sized smaller than the tissue fragments. In many embodiments cavitation with a waterjet is used to fragment the tissue comprising the intact stem cells. The waterjet may comprise a waterjet immersed in a liquid comprising water so as to form a plurality of shedding pulses. The plurality of shedding pulses can be generated with a frequency sufficient to fragment the tissue. The shedding pulses can generate cavitations that fragment the tissue.
