A device for preparing an opening in tissue for implantation of an implant. The device includes a tool adapted to be coupled to an energy source, an augmentation element of a thermoplastic material, and a counter element. A tool contact surface and a first augmentation element contact surface together form a first interface, and a second augmentation element contact surface and a counter element contact surface together form a second interface. The device is configured to be being inserted into an opening in the tissue and configured for the augmentation element to be compressed between the tool and the counter element while at the same time energy is coupled into the tool.
