Medical device for introducing into a bodily orifice or cavity of an individual

Medical device (1) for introduction into a bodily orifice or cavity of an individual, having a first elongated hollow body (2) and a second elongated hollow body (3) in which the first hollow body (2) is accommodated, wherein a step-shaped transition (5) is present between an end of the second hollow body (3), from which the first hollow body (2) projects with its distal end, which is intended for introduction into a bodily orifice or cavity of an individual, and this first hollow body (2), which transition runs in the radial direction,

• wherein
• the distal end of the first hollow body (2) is configured as a tip part (4) or has a tip part (4), which runs all the way to the second hollow body (3), forming the step-shaped transition (5),
• that a shaping device (6, 7;
• 6, 10) that can be displaced in its longitudinal direction is accommodated between the tip part (4) and the second hollow body (3),
• and that the shaping device (6, 7;
• 6, 10) is formed, in the region of the step-shaped transition (5), in such a manner that by means of its displacement in the longitudinal direction in question, the tip part (4) can be expanded in the radial direction, toward the step-shaped transition (5), with cancellation of the latter, at least to a great extent, to form a step-free transition (9) and/or the second hollow body (3) can be contracted in the radial direction, toward the step-shaped transition (5), with cancellation of the latter, at least to a great extent, to form a step-free transition (9).
