A suture passing device , comprising: a handle ; a shaft coupled to the handle , the shaft comprising a sharp distal tip that defines a shaft axis (A), the shaft defining a lumen ; a jaw assembly housed within the shaft , the jaw assembly comprising a first jaw member (41cc-1) and a second jaw member (41cc-2), the first jaw member and the second jaw member (41cc-2) being movable with respect to each other between a closed position and an open position, the jaw assembly comprising a push-pull suture capturing mechanism, the push-pull suture capturing mechanism comprising a first set of teeth formed on the first jaw member (41cc-1) and a second set of teeth formed on the second jaw member (41cc-2); and an actuating mechanism coupled to the jaw assembly and configured to move the jaw assembly between the closed position and the open configuration, wherein the first jaw member (41cc-1) and the second jaw member (41cc-2) are biased away from each towards the open position and moved to the open position when the actuating mechanism moves the jaw assembly distally with respect to the shaft such that first jaw member (41cc-1) and the second jaw member (41cc-2) each diverge from the shaft axis when exiting the shaft , wherein the first jaw member (41cc-1) and the second jaw member (41cc-2) are moved to the closed position when the actuating mechanism is moved to retract the jaw assembly proximally with respect to the shaft , characterized in that : a third jaw member (41cc-1) is stacked on and movable in unison with the first jaw member (41cc-1); and a fourth jaw member (41cc-2) is stacked on and movable in unison with the second jaw member (41cc-2), wherein the third jaw and the fourth jaw converge and diverge from each other in unison with the first jaw and the second jaw. a handle ; a shaft coupled to the handle , the shaft comprising a sharp distal tip that defines a shaft axis (A), the shaft defining a lumen ; a jaw assembly housed within the shaft , the jaw assembly comprising a first jaw member (41cc-1) and a second jaw member (41cc-2), the first jaw member and the second jaw member (41cc-2) being movable with respect to each other between a closed position and an open position, the jaw assembly comprising a push-pull suture capturing mechanism, the push-pull suture capturing mechanism comprising a first set of teeth formed on the first jaw member (41cc-1) and a second set of teeth formed on the second jaw member (41cc-2); and an actuating mechanism coupled to the jaw assembly and configured to move the jaw assembly between the closed position and the open configuration, wherein the first jaw member (41cc-1) and the second jaw member (41cc-2) are biased away from each towards the open position and moved to the open position when the actuating mechanism moves the jaw assembly distally with respect to the shaft such that first jaw member (41cc-1) and the second jaw member (41cc-2) each diverge from the shaft axis when exiting the shaft , wherein the first jaw member (41cc-1) and the second jaw member (41cc-2) are moved to the closed position when the actuating mechanism is moved to retract the jaw assembly proximally with respect to the shaft , characterized in that : a third jaw member (41cc-1) is stacked on and movable in unison with the first jaw member (41cc-1); and a fourth jaw member (41cc-2) is stacked on and movable in unison with the second jaw member (41cc-2), a third jaw member (41cc-1) is stacked on and movable in unison with the first jaw member (41cc-1); and a fourth jaw member (41cc-2) is stacked on and movable in unison with the second jaw member (41cc-2), wherein the third jaw and the fourth jaw converge and diverge from each other in unison with the first jaw and the second jaw. <EOS>
