A method for removing material from a vesicular object by securing the object, penetrating the object with a pipette, such pipette having a sealed distal tip and an aperture, advancing said pipette into the object in such a manner as to place the aperture directly adjacent to the material to be removed from the object, applying vacuum inside the pipette thereby drawing the material to be removed from the object into the pipette, and removing the pipette from the object in such a manner as to cut or otherwise separate the material in the pipette from the object thereby leaving the material removed from the object in the pipette while leaving the object undamaged.
