Problems solved by technology

Difficulty has been encountered in securing sutures against movement relative to body tissue.
However, the knot weakens a portion of the suture and reduces the overall force transmitting capability of the suture.

embodiment

of FIG. 48-55

[0507] Referring to FIGS. 48-51, the ultrasonic energy application apparatus 640 of FIG. 25 includes a rigid energy transmission member 1170 and a rigid tubular force transmitting member 1172 extends around and is coaxial with the cylindrical energy transmission member 1170. A biasing assembly 1174 continuously urges the force transmitting member 1172 toward the left (as viewed in FIG. 48) with a constant predetermined force. The illustrated embodiment of the biasing assembly 1174 includes a helical spring 1176 which is disposed between an annular flange 1178 on a reaction member 1180 and an annular piston 1182. The annular piston 1182 is fixedly connected to a housing 1184. The housing 1184 is connected to the tubular force transmitting member 1172. The reaction member 1180 is fixedly connected to a manually engagable handle 11186.

[0508] A trigger 1188 is pivotally connected with the handle 1186. The trigger 1188 is manually pivotal in a clockwise direction (as viewed...

Abstract

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 797,685, filed Mar. 9, 2004, the contents of which are herein incorporated by reference.FIELD OF THE INVENTION [0002] The present invention relates to methods and devices for securing body tissue by using ultrasonic vibratory energy and other forms of energy. BACKGROUND OF THE INVENTION [0003] Difficulty has been encountered in securing sutures against movement relative to body tissue. A knot may be tied in a suture to prevent loosening of the suture. However, the knot weakens a portion of the suture and reduces the overall force transmitting capability of the suture. It has been suggested that a suture could be secured using a suture retainer in the manner disclosed in U.S. Pat. Nos. 5,735,875 and 6,010,525. [0004] When a suture retainer is used to maintain a suture in a desired position relative to body tissue, the material of the suture retainer may be pressed ...
