Said device (1) protects the bladder lumen from bacterial invasion when the functional body (2) is inserted into the bladder and helps an infected bladder during mechanical cleaning and subsequent healing. The invention also relates to the use of the device (1) for medical, in particular prophylactic and therapeutic purposes. ## Claims ### Claim 1 Device for protecting and cleaning an urinary bladder lumen, at least comprising: a functional body whose spatial dimensions are variable, wherein the functional body is at least partially transformable from a smaller state to a larger state. ### Claim 2 (depends on 1) The device according to claim 1, wherein the functional body at least partially comprises a material that is permeable to liquids. ### Claim 3 (depends on 1) The device according to claim 1, wherein the material of the functional body is selected from the group consisting of close-meshed tissue, porous foil, and fine-pored foam. ### Claim 4 (depends on 1) The device according to claim 1, wherein the material of the functional body is a self-inflating material. ### Claim 5 (depends on 1) The device according to claim 1, wherein the functional body is biologically degradable. ### Claim 6 (depends on 1) The device according to claim 1, wherein the functional body is at least partially moistened and/or coated with an antimicrobial substance. ### Claim 7 (depends on 1) The device according to claim 1, wherein the functional body is divided into at least two segments. ### Claim 8 (depends on 1) The device according to claim 1, wherein in the smaller state the functional body is at least partially folded, rolled and/or pressed. ### Claim 9 (depends on 1) The device according to claim 1, wherein in the smaller state the functional body has a diameter of at most 4-6 mm. ### Claim 10 (depends on 1) The device according to claim 1, wherein the functional body includes at least two layers. ### Claim 11 (depends on 1) The device according to claim 1, wherein, at the outside, the functional body is provided with a cover. ### Claim 12 (depends on 1) The device according to claim 1, further comprising a guiding element, is provided. ### Claim 13 (depends on 1) as Method for protecting and cleaning an urinary bladder lumen comprising providing the device of claim 1, and protecting and cleaning the urinary bladder lumen, wherein the functional body of the device is at least partially transformed from a smaller state to a larger state during said protecting and cleaning. ### Claim 14 (depends on 2) The device according to claim 2, wherein the material permeable to liquids is a material having holes or pores. ### Claim 15 (depends on 7) The device according to claim 7, wherein the functional body is divided into at least 4 to 32 segments. ### Claim 16 (depends on 9) The device according to claim 9, wherein the diameter is the smaller state is about 5 mm. ### Claim 17 (depends on 10) The device according to claim 10, wherein the at least two layers comprise an outer and an inner layer and preferably an inner layer and an outer layer, and the inner layer is provided with a gas and/or water proof coating, and/or the outer layer has a structured surface. ### Claim 18 (depends on 17) The device according to claim 17, wherein said gas and/or water proof coating is temporary and/or the structured surface is provided with pimples or embossments. ### Claim 19 (depends on 11) The device according to claim 11, wherein the cover is a forming cover. ### Claim 20 (depends on 12) The device according to claim 12, wherein the guiding element is a guiding pin.
