Abstract
A device for removing material from within the body, includes an elongated element formed from hollow segments sequentially interconnected at effective hinges. The device assumes an insertion configuration for insertion of the segments sequentially through an opening of a first dimension into the body. A portion of the elongated element inserted into the body progressively assumes a material removing configuration in which a relative position of each segment relative to an adjacent segment is delineated by the effective hinge together with additional abutment surfaces defining a fully deflected state of the effective hinge. The material removing configuration has at least two dimensions exceeding the first dimension. At least two of the segments are formed with at least one opening, typically provided with a cutting configuration, deployed so as to receive material into a hollow volume of the segment during progressive formation of the material removing configuration as the elongated element is advanced.
