Method and device for securing body tissue
First Claim
1. A surgical device for securing tissue comprising:
- an energy transmission member configured to contact a retainer;
a tubular member including a proximal end and a distal end, the tubular member is movable along a linear path relative to the energy transmission member from a first position to a second position, the tubular member configured to engage a periphery of the retainer to position the retainer substantially transverse to a longitudinal central axis of the energy transmission member, the distal end tubular member having a flange configured such that a retainer is positionable between the flange and the energy transmission member; and
a transducer positioned in the surgical device and operably connected to the energy transmission member to deliver energy to the retainer through the energy transmission member.

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.

9. A surgical device for securing tissue comprising:
-
an energy transmission member configured to contact a retainer; a tubular member including a proximal end and a tubular end and configured to receive at least a portion of the retainer, the tubular member being slidably positionable over at least a portion of the energy transmission member and configured to move between a first position and a second position relative to the energy transmission member the distal end of the tubular member having a flange configured such that a retainer is positionable between the flange and the energy transmission member; a transducer operably connected to the energy transmission member to deliver energy to the retainer through the energy transmission member; an actuated switch that enables transmission of energy through the energy transmission member; and a safety switch operably connected to the transducer and configured to limit delivery of energy when the tubular member is in the second position. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A surgical device for securing tissue comprising:
-
an energy transmission member configured to contact a retainer; a force transmitting member movable with the respect to the energy transmission member from a first position to a second position, the force transmitting member having a flange disposed on a distal end of the force transmitting member; an elongated insulation sleeve movable with respect to both the energy transmission and force transmitting members; and a transducer operably connected to the energy transmission member to deliver energy to the retainer, wherein the elongated insulation sleeve is further positionable to cover a gap between an end surface of the energy transmission member and the flange of the force transmitting member to limit the application of energy from the transducer to suture and adjacent tissue. - View Dependent Claims (17, 18, 19)
