Abstract
An apparatus comprising a plurality of chambers for receiving an associated plurality of staples, each formed with a shape memory that allows the staple to adopt a straightened configuration, when placed in a stapler, and a deployed configuration for suturing when released from the stapler; and a sleeve moveable relative to the chambers between a first position, in which the staples are trapped by the sleeve within the chambers in the straightened configuration, and a second position, whereby the staples are freed to adopt the deployed configuration, wherein the sleeve is adapted to move between the first and second positions by rotating relative to the chambers.
