Fixation device, implant and implant assembly for use in tissue repair

An implant assembly for use in tissue repair, the implant assembly comprising:

• a fixation device having a body comprising:
• a first surface adapted to face towards a bone;
• a second surface adapted to face away from the bone;
• and
• a plurality of apertures, each aperture extending through the fixation device body from the first surface to the second surface;
• and
• a flexible elongate implant coupled to the fixation device, the implant having a multifilament structure comprising filaments which are of a metallic or non-metallic material;
• in which the implant is coupled to the fixation device by passing through the apertures, and comprises a loop having a first end that is secured to the fixation device and a second end which can be releasably coupled to the fixation device following passage through or around a bone, for securing the implant assembly relative to the bone;
• in which the fixation device comprises a first portion comprising the plurality of apertures, the apertures cooperating to anchor the first end of the loop;
• in which the fixation device comprises a second portion coupled to the first portion via a bridge extending between the first and second portions;
• in which the fixation device comprises first and second channels located between the first and second portions, the channels each extending through the fixation device from the first surface to the second surface and having an open end disposed at a perimeter of the fixation device and a closed end disposed inwardly of the perimeter, the closed end defining a detent for the implant;
• and
• in which:
• the channels each comprise a main part having a width;
• and the detents of each channel have a width which is greater than the width of their main parts.
