Implant
An implant with which prostates of different sizes can be treated is achieved by the fact that the length of a deployed implant is modifiable to a variable extent. Through the change of length of a stretched-out wire structure of the implant, the implant can be adapted individually to the patient anatomy and the outcome of treatment can thus be improved.
1 . A removable implant for treating a urinary tract of a person by application of a local ischemic pressure to tissue of urinary organs comprising a wire structure with at least two wires, the implant in a folded state being insertable, with a distal end to the front, into a urethra and being deployed to provide the wire structure in the urethra in order to treat the tissue, wherein a length of the implant is modifiable to a variable extent,
wherein the removable implant further comprises a sleeve configured to be pushed over a proximal end region of the at least two wires, the sleeve being freely displaceable over the proximal end region of the wires, and
wherein when the length of the implant is shortened via displacement of the sleeve, the sleeve is entirely located between the proximal end region of the implant and a distal end of the implant, such that at least a portion of the wire structure is exposed at the proximal end region.
2 . The removable implant as claimed in claim 1 , wherein the sleeve is rigidly connectable to the at least two wires, a relative movement between the wires and the sleeve being suppressed by the rigid connection.
3 . The removable implant as claimed in claim 1 , wherein the sleeve is a screw-type sleeve, a crimp sleeve, a click-fit sleeve, a latching sleeve or a sleeve having an inner passage whose diameter corresponds precisely to the sum of the diameters of the wires.
4 . The removable implant as claimed in claim 1 , wherein the length of the implant is adjusted by the positioning of the sleeve on the at least two wires, the length of the deploying portion of the wires being set by the fixing of the sleeve on the wires.
5 . The removable implant as claimed in claim 3 , wherein the screw-type sleeve can be assembled from a first part and a second part, the first part having an inner thread and the second part having a sleeve with an outer thread, the second part being able to be screwed together with the first part, and an elastic ring being able to be clamped between the first part and the second part.
6 . The removable implant as claimed in claim 1 , wherein the sleeve is able to be fixed to the wires outside the person before a treatment or inside the person during the treatment.
7 . The removable implant as claimed in claim 1 , wherein the sleeve is able to be fastened releasably to the wires.
8 . The removable implant as claimed in claim 1 , wherein the sleeve has an external diameter of less than 3 mm.
9 . The removable implant as claimed in claim 1 , wherein at least one of the wires, or a holding element of the implant, has markings, on the basis of which the length of the implant or the position of the sleeve is adjustable.
10 . A removable implant for treating a urinary tract of a person by application of a local ischemic pressure to tissue of urinary organs comprising a wire structure with at least two wires, the implant in a folded state being insertable, with a distal end to the front, into a urethra and being deployed to provide the wire structure in the urethra in order to treat the tissue, and having a holding element, by which the position of the implant inside the urinary tract is able to be fixed, wherein a length of the holding element is modifiable to a variable extent,
wherein the removable implant further comprises a sleeve configured to be pushed over a proximal end region of the at least two wires, the sleeve being freely displaceable over the proximal end region of the wires, and
wherein when the length of the implant is shortened via displacement of the sleeve, the sleeve is entirely located between the proximal end region of the implant and a distal end of the implant, such that at least a portion of the wire structure is exposed at the proximal end region.
11 . The removable implant as claimed in claim 10 , wherein a sleeve is able to be pushed over a proximal end region of the holding element.
12 . The removable implant as claimed in claim 10 , wherein the holding element has, at a distal end, predetermined breaking points, by which the length of the holding element can be changed in a targeted manner.
13 . A removable implant for treating a urinary tract of a person by application of a local ischemic pressure to tissue of urinary organs comprising a wire structure with at least two wires, the implant in a folded state being insertable, with a distal end to the front, into a urethra and being deployed to provide the wire structure in the urethra in order to treat the tissue, and having a holding element, by which the position of the implant inside the urinary tract is able to be fixed, wherein, a length of the implant and the length of the holding element are modifiable to a variable extent,
wherein the removable implant further comprises a sleeve configured to be pushed over a proximal end region of the at least two wires, the sleeve being freely displaceable over the proximal end region of the wires, and
wherein when the length of the implant is shortened via displacement of the sleeve, the sleeve is entirely located between the proximal end region of the implant and a distal end of the implant, such that at least a portion of the wire structure is exposed at the proximal end region.
14 . The removable implant as claimed in claim 1 , wherein the sleeve is shorter in length than the wire structure.
