A device may include a sheath including a lumen, a distal end, and a proximal end. The device may further include an end-effector unit and an elongate member connected to the end-effector unit. The end-effector unit and the sheath may be movable relative to each other to achieve a first state of the end-effector unit and a second state of the end-effector unit. Moreover, the medical device may include a handle having a first handle portion connected to the proximal end of the sheath, a second handle portion connected to the proximal end of the elongate member, and a compliant member longitudinally aligned with the sheath between the first handle portion and the second handle portion. The first and second handle portions may be configured such that relative movement of the first and second handle portions causes the end-effector to move between the first and second states.
