Abstract: A needle assembly (20, 120, 220, 320) is provided that includes a needle (22) and a suture (24) coupled to the needle (22), and a needle guide tool (30, 130, 230, 330). The needle guide tool (30, 130, 230, 330) is configured to pass the needle (22) and the suture (24) through tissue of a body portion of a subject, and includes a needle guide (34, 134, 334), which is shaped so as to define a needle-guide surface (36, 136) that is configured to slidably contact a body-portion surface of the body portion without penetrating the body¬ portion surface. The needle guide tool (30, 130, 230, 330) also includes a proximal needle holder (40), which releasably holds the needle (22) such that a longitudinal segment (42, 142) of the needle (22) runs alongside the needle-guide surface (36, 136), such that sliding of the needle-guide surface (36, 136) distally along the body-portion surface advances the needle (22) within the body portion beneath the body -portion surface at a maximum depth set by the needle guide tool (30, 130, 230, 330). Other embodiments are also described.
