A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. In an embodiment, the device includes a proximal end and a distal end, as well as an advancement unit for longitudinally advancing the flexible elongated element toward the distal end such that a proximal end of the elongated element may pass from the distal end of said device with sufficient force to pass through the portions of the subject. The device also includes a securing unit for variably adjusting a securing force applied by the flexible elongated element to secure together the portions of the subject.

What is claimed is: 1. A device for fixing a flexible elongated element to a portion of a subject, said device comprising: structure for retaining the flexible elongated element; an advancement mechanism for longitudinally advancing the flexible elongated element from a proximal end of said device
What is claimed is: 1. A device for fixing a flexible elongated element to a portion of a subject, said device comprising: structure for retaining the flexible elongated element; an advancement mechanism for longitudinally advancing the flexible elongated element from a proximal end of said device toward a distal end of said device with sufficient force to pass the element through the portion of the subject; a securing mechanism for securing the element to the subject and for variably adjusting a securing force applied by the flexible elongated element to the portion of the subject; and a motor, said motor being connected to said advancement mechanism through a first transmission mechanism such that when said motor is energized with a first polarity, said advancement mechanism will advance the flexible elongated element, and said motor being connected to said securing mechanism through a second transmission mechanism such that when said motor is energized with a second polarity, the securing mechanism will secure the element to the subject and variably adjust the securing force. 2. A suturing instrument for fixing suture wire to a portion of a subject, the suturing instrument comprising: a housing; a shaft extending from the housing and having a distal end; a pair of opposed jaws located at the distal end of the shaft, at least one of the jaws being movable relative to another of the pair of jaws; an advancement mechanism adapted to advance the suture wire toward the distal end and in the movable jaw; and a cutting unit comprising: a cutter in the movable jaw and adapted to cut the suture wire; a cutter actuator extending toward the distal end of the shaft; and a flexible coupling adapted to maintain an operative connection between the cutter actuator and the cutter without preventing the movable jaw from moving. 3. A suturing instrument for fixing suture wire to a portion of a subject, the suturing instrument comprising: a housing; a shaft extending from the housing and having a distal end; a pair of opposed jaws located at the distal end of the shaft, at least one of the jaws being a movable relative to another of the pair of jaws; a channel in the shaft and in the movable jaw, the channel having a portion that is flexible so as to provide a pathway to guide suture wire from the distal end to the movable jaw without preventing the movable jaw from moving; an advancement mechanism adapted to advance the suture wire in the channel; and a securing mechanism adapted to secure suture wire to the subject and to variably adjust a securing force applied by the suture wire to the portion of the subject by rotating the pair of jaws about an axis lying along at least a portion of the shaft. 4. A suturing instrument, comprising: a housing; an elongated shaft extending distally from the housing and having a distal end; a pair of opposed jaws located at the distal end of the shaft, at least one of the jaws being movable relative to another of the pair of jaws; a source of suture wire; and a drive mechanism adapted to move the suture wire distally in the shaft and in one of the jaws, and to rotate the jaws about an axis lying along at least a portion of the shaft. 5. The instrument of claim 4, wherein the drive mechanism includes a single motor that can move suture wire distally in the shaft and rotate the jaws about the axis. 6. The instrument of claim 5, wherein the motor rotates in a first direction to move suture wire and rotates in a second direction different from the first direction to rotate the jaws. 7. The instrument of claim 5, further comprising: a switch that when moved adjusts a polarity of electrical energy provided to the motor. 8. The instrument of claim 4, further comprising: a cutter adapted to cut the suture wire near the distal end. 9. The instrument of claim 8, wherein the cutter cuts suture wire in the first of the pair of jaws. 10. The instrument of claim 8, wherein the cutter is adapted to cut the suture wire so as to form a sharp point on the suture wire. 11. The instrument of claim 4, wherein the drive mechanism engages a side of the suture wire to move the suture wire. 12. The instrument of claim 11, wherein the drive mechanism includes at least one drive wheel that contacts the suture wire. 13. The instrument of claim 4, wherein the drive mechanism is controllable to variably adjust a securing force applied by the suture wire a material. 14. The instrument of claim 4, wherein the jaws include opposing jaw surfaces adapted to grip tissue therebetween. 15. The instrument of claim 4, wherein the jaws have opposed channels therein to receive the suture wire. 16. The instrument of claim 15, wherein the drive mechanism moves the suture wire through a channel in a first of the jaws, through tissue, and into a channel in a second of the jaws. 17. The instrument of claim 4, wherein the housing is near a proximal end of the instrument and includes a handle, and further wherein the shaft comprises an elongated tube extending between the housing and the distal end of the instrument, such that the distal end of the instrument is sufficiently spaced from the handle to facilitate disposition and operation of the instrument in a closed surgical procedure. 18. The instrument of claim 4, further comprising: a cartridge that contains the source of suture wire, the cartridge being removable from the instrument. 19. This instrument of claim 4, wherein each of the pair of jaws are moveable relative to the shaft. 20. The instrument of claim 19, wherein each of the jaws are pivotable relative to the shaft about axes lying transverse to the shaft. 21. A suturing instrument, comprising: a housing; an elongated shaft extending distally from the housing and having a distal end; a pair of opposed jaws located at the distal end of the shaft, the jaws being arranged for rotation relative to an axis lying along at least a portion of the shaft; a source of suture wire; and a drive mechanism adapted to move the suture wire distally in the shaft and in one of the jaws; wherein the drive mechanism is adapted to move suture wire from a first of the pair of jaws, through tissue positioned between the opposed faces of the jaws, and into a second of the pair of jaws when the jaws are partially closed so that the opposed faces are non-parallel. 22. The instrument of claim 21, further comprising: a rotation unit adapted to rotate the jaws about the axis. 23. The instrument of claim 21, wherein at least one of the opposed faces of the jaws includes a recess to receive at least a portion of tissue so the portion of tissue is not compressed when the jaws are closed. 24.
