The invention relates to an occlusion device which consists of an interlaced structure (2) of thin wires or threads (2), the ends of the wires or threads (4) converging in a holder (10). The aim of the invention is to allow the occlusion device to be retrieved or repeatedly coupled to a surgical instrument. For this purpose, the holder (10), on its free end, has a top section (14) with an eyelet (16) in the form of a crossbore which can be received and retained by an implantation or explantation instrument (100, 200) in a form-fit manner. The invention also relates to a surgical instrument (100) for implanting or explanting an implant having said holder (10) . The surgical instrument has gripping pliers (102) the jaws (103, 104, 105) of which can be opened or closed by a push-pull system and the inside of which is configured in such a manner as to encircle the top section (14) of the holder (10) of the implant in a form-fit manner.
