A medical device (100, 400, 500) including an elongate member (101) having a proximal end (122), a distal end (103), and a lumen (124) extending therebetween. The medical device may further include an end-effector (102) disposed at the distal end of the elongate member, the end-effector may include a first arm (112), the first arm may have a distal end (121), a proximal end (118), and an opening (119) configured to receive a needle therein. The medical device may also include a second arm (104) movably connected to the first arm and configured to alternate between a closed position and an open position relative to the first arm, wherein the second arm is movably connected to the first arm at a pivot point (114) disposed at a location closer to the distal end (125) of the second arm than the proximal end (107) of the second arm. |
