Instruments and techniques to pass a suture, particularly in instances where access to confined spaces and the ability to pass a suture through difficult to penetrate materials are needed. According to certain embodiments, a suture passer is provided including a housing, a needle assembly, and a barrel assembly. The needle assembly may include a needle that is displaceable along a linear motion axis of the housing, and which is adapted to engage a suture. The barrel assembly may include a foot having an opening in a proximal facing surface to receive passage of the needle. The foot may include an elbow having proximal and distal portions, with the proximal portion having a distal facing surface that extends along a proximal portion axis diverging distally away from the motion axis, and the distal portion extending distally from the proximal portion and having a proximal facing surface that extends along a distal portion axis that is arranged transverse to the motion axis.
