A high pressure fluid jet system is provided, which is useful for cutting hard material during a surgical procedure. The cutting of hard material is more efficient as the system delivers abrasive solid particles with the high pressure fluid. A method of effecting cutting during a surgical procedure is also provided. In an exemplary embodiment, a surgical tool that is effective to deliver a pressurized stream of fluid through a nozzle is provided, and the pressurized stream of fluid is delivered through the surgical tool and out of the nozzle to hard material within a patient to effect cutting of the hard material within the patient in a desired pattern. The fluid that cuts the hard material can include a delivery liquid having a plurality of abrasive solid particles that are formed from an organic material. The abrasive solid particles can be entrained in the pressurized fluid stream or the pressurized fluid stream can erode a solid or suspension form of the abrasive particles.
