DETAILED DESCRIPTION

[0040] FIG. 1 shows an exemplary embodiment of a system 1 according to the invention for implanting a medical implant 2 in the human or animal body. The system 1 comprises a wire-like element 3 for connecting the system 1 to the medical implant 2. The system 1 further comprises a double-lumen guide tube 4 for the wire-like element 3 and a handle 5 for handling the system 1.

[0041] The medical implant 2 is arranged at the proximal end of the guide tube 4 and the handle 5 is arranged at the distal end of the guide tube 4, wherein proximal concerns the end of the guide tube 4 facing the human or animal body and distal concerns the end of the guide tube 4 facing away from the human or animal body.

[0042] The wire-like element 3 is fixed with a first end 9 to the handle 5, is guided through a first lumen 6 of the double-lumen guide tube 4 to the medical implant 2, subsequently engages with a connecting device 8 of the medical implant 2 and is then guided through a second lumen 7 of the double-lumen guide tube 4 to the handle 5. At the handle 5, the second end 10 of the wire-like element 3 is detachably fixed.

[0043] According to the embodiment example of FIG. 1, the system 1 according to the invention further comprises an implantation catheter 15, by means of which the medical implant 2 is advanced to the implantation site in the human or animal body by means of the double-lumen guide tube 4.

[0044] The wire-like element 3 consists, for example, of a metal, in particular stainless steel, and has a diameter of 0.1 mm to 0.5 mm, in particular 0.2 mm.

[0045] The double-lumen guide tube 4 consists, for example, at least partially of a plastic and has a diameter of 1.0 mm to 2.0 mm, in particular 1.76 mm.

[0046] The connecting device 8 of the medical implant 2 is preferably designed as an eyelet or loop.

[0047] A so-called pusher is arranged between the implantation catheter 15 and the handle 5 in order to move the double-lumen guide tube 4 and the medical implant 2 fixed therein through the implantation catheter 15.

[0048] Furthermore, a Y-connector can be arranged at the transition between implantation catheter 15 and double-lumen guide tube 4, for flushing the system 1 according to the invention, in particular the implantation catheter 15.

[0049] FIG. 2 shows a detailed view of the connection of the system 1 according to the invention with a medical implant 2 at the proximal end of the system 1. The double-lumen guide tube 4 with the medical implant 2 attached to it emerges from the implantation catheter 15. The medical implant 2 is connected to the system 1 according to the invention by the wire-like element 3, wherein the wire-like element 2 engages a connecting means 8 of the medical implant. The connecting device 8 of the medical implant is formed, for example, as an eyelet or loop. On their way to the distal end of the system 1 according to the invention, the two ends 9, 10 of the wire-like element are guided through the first lumen 6 and the second lumen 7 of the double-lumen guide tube 4.

[0050] FIG. 3 is a detailed view of a handle 5 of a system 1 according to the invention for implanting a medical implant 2 in the human or animal body. A first end 9 of the wire-like element 4 is fixedly attached to the handle 5. For this purpose, the wire-like 4 has, for example, a nipple 12 at the first end, which engages in a corresponding recess 13 on the handle 5. However, other fixations are also possible, such as gluing, welding, soldering or other connection techniques. The second end 10 of the wire-like element 4 is detachably connected to the handle 5, for example by means of a clamping mechanism 14.

[0051] After a successful implantation of the medical implant 2, the connection between second end 10 of the wire-like element 4 and the handle 5 is released and the wire-like element 4 is pulled out of the connection device 8 of the medical implant 2 to release the connection between the system 1 according to the invention and the medical implant 2.

[0052] According to an expedient variant of the invention, the clamping mechanism 14 can comprise a safety device (not shown) which prevents unintentional actuation of the clamping mechanism 14. The safety device is designed, for example, as a latch.

[0053] FIG. 4 shows a detailed view of a medical implant 2 connected to a system 1 according to the invention. The double-lumen guide tube 4 emerges from the implantation catheter 15. Through the first lumen 6 of the double-lumen guide tube 4, the wire-like element 3 is guided from the handle 5 of the system 1 according to the invention to the medical implant 2. The wire-like element 3 engages the connection device 8 of the medical implant 2 and is guided back to the handle 5 of the system 1 according to the invention through the second lumen 7. A first end 9 of the wire-like element 3 is fixed to the handle 5, while the second end 10 is detachably fixed to the handle 5. To eject the medical implant 2 from the system 1 according to the invention, the releasable connection between the handle 5 and the second end 10 of the wire-like element 3 is released and the wire-like element is pulled out of the double-lumen guide tube 4 by means of the handle 5 and the first end 9 fixed thereto, until the wire-like element 3 no longer engages the connection device 8 of the medical implant 2. Subsequently, the double-lumen guide tube 4 can be pulled out of the implantation catheter 15 and finally the implantation catheter 15 is removed from the human or animal body.

[0054] FIG. 5 shows a cross-sectional view of a double-lumen guide tube 4 of a system 1 according to the invention. According to the embodiment example shown in FIG. 5, the double-lumen guide tube 4 comprises two internal tube-like elements 11, which form the first lumen 6 and the second lumen 7 of the double-lumen guide tube 4. The two inner tube-like elements 11 are, for example, each formed as a stainless steel helix.
