- the no when in contact killed with the surface of the functional body so that an accumulation of pathogens in the bladder prevented and the healing is accelerated.
- Functional body are preferably arranged such that they close the interstices of the preceding segments. Because the distances between the segments at
- the functional body is at least partially folded in the smaller state, rolled up
- the functional body in the smaller state have a diameter of at most 4-6 mm, preferably about 5 mm.
- the functional body in the larger state preferably at least partially
- the functional body has at least two layers, preferably an inner layer and an outer layer.
- the inner layer can in particular with one, preferably temporarily, water and / or gas-tight
- Functional body is introduced for example by means of a fluid (liquid, gas) by means of a pressure spray or other devices from the outside, is ensured by the coating of the inner layer that sufficient for the unfolding pressure within the
- the coating dissolves independently after a certain time, so that the gas or liquid exchange within the
- the outer layer can be a textured surface
- the functional body is externally provided with a, preferably shaping, shell.
- a Guide element preferably a guide pin, which causes sufficient rigidity of the functional body.
- the functional body can be brought about a guide pin to a diameter of about 5 mm, for example, for introduction into the bladder via the urethra by folding and winding around a guide pin.
- the invention further generally relates to the use of the device for medical, in particular prophylactic and therapeutic, purposes.
- the invention encompasses the use of the device according to the invention as a type of catheter for protecting and cleaning the device
- the device according to the invention is in the form of a variable in size
- the tightly folded allows the introduction into the urinary bladder via the urethra in the manner of known catheter.

- FIG. 1 shows schematic representations of a preferred embodiment of a device according to the invention.
- the device 1 comprises a functional body 2, the
- antimicrobial coating may consist. This
- Functional body 2 can be used as a temporary implant in the
- Bladder 3 of a human are introduced (Fig. 2A to 2C).
- a functional body 2 which is to fill the entire bladder space to be fully functional, could not pass through the urethra 4 due to its large volume as a catheter.
- the introduction is therefore preferably in the folded, rolled state in the manner of a
- Functional body 2 allows the free passage of urine (Fig. 1B). At the same time blocks and prevents the
- Functional body 2 the ascending germ migration from the urethra 4 into the bladder 3 and from the bladder 3 into the ureter 5 and kidney 6 ( Figures 2A and 2C).
- An antimicrobial coating of the functional body tissue can, in an advantageous embodiment of the invention, ensure that the surface of the functional body 2 remains sterile and that germs do not remain on the surface of the body
- tissue area of the functional body 2 allows the creation of a large contact area with a correspondingly large area with antimicrobial coating, which keeps the tissue area of the functional body 2 sterile.
- the close-meshed, fine-pored tissue of the functional body 2 allows the free passage of urine. Due to the tightness of the tissue, associated with a variety of cells in
- Miniature format remains only a very small distance between colonized urinary bladder epithelia and germs in the urine.
- the outer layer of the functional body 2 is preferably provided with tiny, relatively dimensionally stable dimples 7 (FIG. 1B), which mechanically detach and remove germs and biofilms which colonize the internal bladder wall.
- the low elastic restoring forces of the fabric material are used to slightly against the structured surface (nubs 7)
- the functional body 2 of the device 1 according to the invention is in an advantageous embodiment of the invention in several
- Functional body 2 are preferably arranged such that they close the intermediate spaces of the preceding segments 8. Because the distances between the segments 8 at
- the segments 8 must overlap in the smaller, folded state.
- Function body 2 can contact the bubble inner wall almost completely. The access of the germs to the
- Bladder mucosal membranes and in particular to ureters 5 and urethra 4 can be prevented in any case by an antimicrobial coating.
- an antimicrobial coating In the interior of the
- Functional body 2 have germs that can pass almost exclusively through the urethra 4 in the bladder, no pathogenic significance.
- the material of which the functional body 2 consists is preferably provided with bulges 18 which are embossed into the tissue.
- the dimensional stability of the material should be so be sized so that the structures disappear when pressed into the smaller state (catheter shape).
- the inventive device 1 may further include
- Example metal or plastic wrap (Fig. IC, 1D and IE). After insertion into the bladder 3, the guide pin 9 can be pulled out again (FIG. 2B) to pass through the
- Function body 2 initiate by introducing a fluid. This procedure requires that the inner functional layer be rendered water and / or gas tight during installation with a temporary coating (eg, PVA, acrylate, or other self-dissolving materials).
- a temporary coating eg, PVA, acrylate, or other self-dissolving materials.
- the functional body 2 should only stay in the bladder 3 for a limited time of up to 3 months to the
- the functional body 2 does not have to be removed from the outside by another intervention, it can be applied in the form of biodegradable materials, so that they decompose with time in the urine into the smallest particles which are flushed out via the urethra 4 with the urine , The degradation of the
- FIG. 3 shows a further embodiment of the device according to the invention and its use.
- individual elements 11, 12, 13, 14, 15, 16, 17 of the functional body 2 are respectively pushed over the guide pin 9 into the interior of the preceding functional body element.
- the catheter can be kept very thin.
- the second, smaller element 12 can thus be introduced into the cavity of the larger element 11 folded around the guide pin 9 via the urethra 4 as required, for a larger contact area.
- the overall structure of the functional body is built together in the bladder and adapts flexibly, for example by mechanical bias to the urinary bladder epithelia of the bladder periphery.
- differently functionalized layers can also be installed.
- the outer membrane could be a surface that is provided with an additional antimicrobial principle for sterilizing the urinary bladder 3 or the urinary bladder surface.
