Abstract
A medical device for inserting into a bodily orifice or cavity of an individual, which includes a first longitudinal hollow body and a second longitudinal hollow body that receives the first hollow body. Between the one end thereof and the first hollow body, there is a stepped transition which extends in the radial direction and can pass into an at least substantially step-free transition by virtue of the fact that the first hollow body, in the region of the stepped transition, expands in the radial direction towards the second hollow body and/or that the second hollow body, in the region of the stepped transition, contracts in the radial direction towards the first hollow body.
Claims8
Medical device (1) for introduction into a bodily orifice or cavity of an individual, having a proximal end and a distal end and a first elongated hollow body (2) with a proximal end and a distal end and a second elongated hollow body (3) with a proximal end and a distal end, wherein the first hollow body is accommodated in the second hollow body (3)
- wherein the distal end of the first hollow body (2) is configured as a tip part (4) or has a tip part (4) which has a proximal end and a distal end, wherein the distal end of the tip part (4) is intended for the introduction into a bodily orifice or cavity of an individual, wherein the proximal end of the tip part (4) extends to the distal end of the second hollow body (3), forming a step-shaped transition (5), wherein said step-shaped transition extends in the radial direction of the tip part (4) and the second hollow body (3),
- wherein 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 wherein the shaping device (6, 7;
- 6, 10) has such a shape that by its displacement in the longitudinal direction of the medical device in the region of the step-shaped transition (5), at least one of the proximal end of the tip part (4) and the distal end of the second hollow body have a change in diameter in a radial direction such that both the distal end of the second hollow body and the proximal end of the tip part have equal outside diameters, and the step-shaped transition (5), is transformed, at least to a great extent, into a step-free transition (9).
