1. A medical treatment apparatus comprising an outer tube having a treatment end for disposal at a treatment zone in a patient and remote end opposite to the treatment end, and a plurality of flexible inner tubes disposed in a high energy retracted state at least partially within said outer tube, each inner tube having an optical fiber accommodating hole extending lengthwise therein, each inner tube being non-linear when unconstrained, the high energy retracted state corresponding to each inner tube being constrained by said outer tube, the high energy retracted state of each inner tube corresponding to each inner tube having a shape different from its shape when unconstrained, and wherein said inner tubes are movable relative to said outer tube to cause each inner tube to assume a non-linear extended position at least partly within said outer tube for application of laser energy using a beam which is not parallel with the outer tube, and further comprising a plurality of optical fibers, each optical fiber corresponding to one of said inner tubes and disposed within the optical fiber accommodating hole of said corresponding one of said inner tubes.
