ABSTRACT:
A method for dissolving a solidified mass in vivo, and apparatus for oscillating a fluid into and out from a body area. The method comprises introducing a dissolving agent into a body area, and oscillating an agitating fluid into and out from that body area to stir the dissolving agent therein. Body fluids withdrawn from the body area with the agitating fluid are separated therefrom, and the separated agitating fluid is reintroduced into the body area to further stir the dissolving agent. The apparatus comprises a pump to force fluid into and to draw the fluid from a body area, a trap for collecting body fluids aspirated from the body area, and fluid lines to connect the pump to the trap and the trap to the body area.
