Claim:
1. Apparatus comprising a surgical tool for use with solid particles and a physiological liquid solution, the surgical tool comprising: exactly one shaft unit, which is shaped so as to define a delivery lumen and a drainage lumen; a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; a filter, which is disposed in fluid communication with the drainage lumen, and which is configured to inhibit passage of the solid particles of the solid-liquid composition and allow passage of the physiological liquid solution of the solid-liquid composition; and a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen, at a pulsating hydraulic pressure that periodically varies between positive and negative.
