1. An apparatus for forming a barbed suture comprising:
a tool; a converter operably connected to the tool for transmitting ultrasonic energy to the tool; a gripper for supporting a suture relative to the tool; and a motorized slide for moving the gripper in X, Y, and Z planes relative to the tool from a first position in which the gripper is laterally spaced from the tool to a second position in which the gripper is positioned adjacent the tool such that the suture contacts the tool. |
