Some embodiments relate to a device for delivering shape-memory staples. The device comprises a grippable portion comprising a first actuator; and a delivery portion coupled to the grippable portion. The delivery portion comprises retention walls for retaining the staples within the delivery portion in an elastically deformed configuration and release apertures for releasing the staples to adopt a deployed configuration based on their shape memory. The delivery portion is configured to cause one end of each staple to protrude from the delivery portion in response to actuation of the first actuator. In some embodiments a striking mechanism is coupled to the grippable portion and configured to communicate a striking blow to the delivery portion.
