Title: Fastening device, implant device, locking method, and operation method

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to a fastening device for an implant device as stated in the preamble of claim  1 . 
     TECHNICAL BACKGROUND 
     Implant devices are devices that are adapted for being placed in e.g. human bodies or animals, and that e.g. replace body parts that have been damaged or removed e.g. due to cancer. 
     In order to keep the implant device in place so that it does not move freely within e.g. a human body cavity, it is known to fasten the implant device in position using a fastening device. A known fastening device is a band type device having two ends, where a first end has a hole, and a second end has a protruding part arranged to be placed in said hole in order to lock the two ends of the band type device together after having been looped around an implant device and a body part such as an intestine, thereby fastening the implant device in place. In order for the band ends not to be separated when e.g. a person carrying the implant moves around, the protruding part is of flexible material and has a ball shaped outer end of somewhat larger cross-section than the diameter of the hole, whereby the ball shaped end is elastically deformed when pushed through the hole and regains its shape when leaving the hole, thus keeping the band ends locked to each other. 
     SUMMARY OF THE INVENTION

     Briefly described, the present invention provides a solution for enabling an easy and fully, i.e. 100%, reversible way of keeping an implant in place so that it does not move freely, by providing and placing a fastening device for an implant device into e.g. a body of a patient, where the “patient” is a living creature such as e.g. a human or an animal 
     The invention is now described, by way of example, with reference to the accompanying drawings, in which: 
       FIG. 1  shows schematically a fastening device  2  for an implant device  4  according to one exemplary embodiment of the invention, where the fastening device  2  comprises at least two fastening sections  6 ,  8  (only two fastening sections are shown in the figure), where a first fastening section  6  is arranged with a through hole  10 , a second fastening section  8  is arranged with a protruding part  12 , and where said protruding part  12  is in place in said through hole  10  in a fastening device locking state (for the fastening device locking state, see  FIG. 2 ,  FIG. 1  shows an unlocked fastening device state). As can be seen from the  FIG. 1 , the protruding part  12  on the second fastening section  8  is arranged with a through channel  14  having an inlet  16  and an outlet  18 , said through channel  14  being arranged to receive an implant device feed member  20 , said inlet  16  and outlet  18  being accessible from the exterior  1 ,  3  of the fastening device  2  in said fastening device locking state, wherein the first fastening section  6  is securely locked to the second fastening section  8  when, in said fastening device locking state, said implant device feed member  20  is in place in the through channel  14  and protrudes from both the inlet  16  and the outlet  18  of said through channel  14 . 
     Said through channel  14  may be of any length, i.e. if the protruding part  12  is very thin, said through channel  14  could be similar to a hole. 
     Said inlet  16  and outlet  18  are accessible from the exterior of the fastening device  2  in said fastening device locking state, i.e. said inlet  16  and/or outlet  18  may be accessible from one or more sides of the fastening device  2  in said fastening device locking state, e.g. from one of or from some of the following sides: the outer side, the inner side, or any other side not belonging to the outer side and the inner side, of the fastening device  2 , see e.g.  FIG. 8  showing an embodiment where said inlet  16  is accessible from the exterior of the fastening device  2  by being accessible from the inner side  1  of the fastening device  2  and where said outlet  18  is accessible from the exterior of the fastening device  2  by being accessible from the outer side  3  of the fastening device  2 .
