摘要:
A multi-channel probe (10) having at least three independent longitudinal channels (16, 18, 20, 22) for endoscopically lithiastic obstacles and for destroying mineral deposits in ducts, comprising a hollow tubular element (12) having a distal end (13) and a proximal end (14), characterized in that it is made of a flexible self-supporting material which can be folded or bent inwards, and in that said hollow tubular element (12) is sub-divided into at least three independent longitudinal channels (16, 18, 20, 22) by at least two partition walls (24, 26, 28) arranged lengthwise in the tubular element (12) and substantially parallel to the axis of symmetry thereof.
