A sterile, implantable, non-bioabsorbable device intended to be used to reattach the ends of a lacerated or ruptured tendon in order to repair the tendon and restore its function. It is in the form of small suture-like wires made of metal and synthetic polymer materials, and is permanently implanted into the tendon ends with a dedicated stapler-like tool. Disposable devices intended to assist implantation may be included.
