Abstract

A fluid stream is directed toward tissue to generate a plurality of shedding clouds. The fluid stream can be scanned such that the plurality of shedding clouds arrive a different overlapping locations. Each of the plurality of shedding clouds can remove a portion of the tissue. In many embodiments, an apparatus to ablate tissue comprises a source of pressurized fluid, and a nozzle coupled to the source of pressurized fluid to release a fluid stream, in which the fluid stream generates a plurality of shedding clouds.
