Claim Text:
1. A device for the anchoring of a suture in bone tissue, which device comprises: a suture anchor, the suture anchor comprising an anchor foot with a proximally-facing shoulder; the suture which runs through the anchor foot; an anchoring sleeve with an axially extending through-going sleeve lumen open towards a distal side, the anchoring sleeve sitting against the shoulder, the anchoring sleeve comprising a solid liquefiable thermoplastic material; an insertion tool proximally of the anchoring sleeve; and a guide sleeve with a through-going axial lumen and a distal end open towards a distal side; wherein the insertion tool extends in the lumen of the guide sleeve and is capable of axial movement relative to the guide sleeve; wherein the suture at least in a distal guide sleeve region runs through the axial lumen of the guide sleeve; wherein the insertion tool is equipped for charging the anchoring sleeve with energy for liquefying portions of the solid thermoplastic material; and wherein the thermoplastic material of the anchoring sleeve is capable of being liquefied at least partially due to the energy impinging and is arranged for being forced to flow, in a liquefied state, out and penetrate surrounding bone tissue and thereby anchoring the anchor in the bone tissue.
