Abstract
Surgical instruments and methods are provided. In one aspect, a method of securing a fixation device within an opening in a tissue is provided, including delivering a material in a flowable state to said opening, and changing the state of the material so that the material forms an interference fit that secures the fixation device in the opening.
Claims33
A surgical instrument for tissue fixation comprising:
- a handpiece constructed to be held by a surgeon during a fixation procedure;
- a cannulated tube defining a lumen, mounted on the handpiece;
- a delivery device, constructed to be mounted on the handpiece, for delivering a flowable material to an opening in bone;
- and
- a suture control device for delivering a suture material from a supply to a distal end of the cannulated tube.
25-27. (canceled)
A surgical instrument for tissue fixation comprising:
- a handpiece constructed to be held by a surgeon during a fixation procedure;
- a cannulated tube defining a lumen, mounted on the handpiece;
- and
- a delivery device for delivering a flowable material through the lumen to an opening in bone, the delivery device comprising a heating element for heating said material to a flowable state, the heating element being constructed to heat the material after the material has been delivered, in a non-flowable state, to the opening.
A surgical instrument for tissue fixation comprising:
- a handpiece constructed to be held by a surgeon during a fixation procedure;
- a cannulated tube defining a lumen, mounted on the handpiece, the cannulated tube including a tip portion configured to receive and carry a rigid suture carrying device;
- and
- a heating device, disposed within the cannulated tube.
30-44. (canceled)
A method of securing a tissue to bone, comprising:
- forming an opening in the bone at a first location,
- delivering a flowable material, in a non-liquid state, and a suture to said opening,
- heating the flowable material, in the opening, to cause the material to flow, and
- allowing the flowable material to at least partially solidify and secure a portion of the suture in the opening.
47-49. (canceled)
A method of securing soft tissue to bone comprising:
- coupling a suture to the soft tissue so that a portion of the suture extends from the soft tissue;
- forming an opening in the bone;
- mounting the extending portion of the suture on a suture carrying device;
- inserting the suture carrying device into the opening;
- delivering a flowable material, in a liquid state, to the opening;
- and
- allowing the flowable material to at least partially solidify to secure the suture and suture carrying device in the opening.
