Patent number: 7329263Abstract: A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.Type: GrantFiled: March 9, 2004Date of Patent: February 12, 2008Assignee: Marctec, LLCInventors: Peter M. Bonutti, Lawrence Crainich, Robert C. Allman, Kevin Allaire

Publication number: 20060200199Abstract: The present invention provides a surgical system for securing a suture against relative movement with respect to a body tissue. The surgical system includes a fastener and medical device for positioning and securing a fastener onto a suture. The fastener includes inner and outer members that can slide together and rotate. The suture extends through the inner and outer members so that rotation of the inner member causes it to wrap the suture around it. As the suture is wound around the inner member, the fastener is drawn toward a position against the body tissue. Further rotation of the inner member allows tension to be applied to the suture. The fastener may be bonded to the suture in order to further secure the suture against relative movement with respect to the body tissue.Type: ApplicationFiled: February 21, 2006Publication date: September 7, 2006Inventors: Peter Bonutti, Matthew Cremens, Lawrence Crainich
