ABSTRACT:
An apparatus and method for ultrasonically forming a surgical suture tip from a length of unfinished surgical suture material. The apparatus includes a first tipping die having a first face for contacting a portion of the length of unfinished surgical suture material. A second tipping die having a second face is also provided. At least one mechanical actuator is provided for moving the first face of the first tipping die toward the second face of the second tipping die. A second actuator vibrates at least one of the first and second tipping dies at an ultrasonic frequency of about 15 KHz to 70 KHz. The method of ultrasonically forming a suture tip comprises the positioning a surgical suture between the first face of the tipping die and the second face of the tipping die then vibrating the dies at an appropriate frequency.
