1. A suture applier comprising:
- a shaft having proximal and distal ends;
a length of suture having proximal and distal ends, a surgical needle secured to the distal end of the suture, and a knotted loop in the suture spaced proximally from the needle, wherein said suture is axially aligned with the shaft and wherein said surgical needle and knotted loop extend from the distal end of the shaft;
means at the proximal end of the shaft for securing and selectively applying axial tension on the proximal end of the suture; and
means responsive to tension on the suture for holding the knotted loop at the distal end of the shaft.

Abstract
A suture applier comprises a shaft having proximal and distal ends and carrying a length of suture along its axis. The suture has a surgical needle at its distal end and a knotted loop formed proximally of the needle. The knotted loop is carried at the distal end of the shaft, and a slidable handle is provided at the proximal end for applying axial tension on the suture. In this way, the needle may be used to suture a wound in tissue and may be tied by passing the needle through the knotted loop and closing the loop by pulling on the slidable handle.

10. A suture applier comprising:
-
a shaft having a proximal end, a distal end, an axial passage therethrough, and a port at the distal end of the axial passage; a length of suture having a proximal end, a distal end, a surgical needle at the distal end of the suture, and a knotted loop in the suture spaced proximally from the needle, said suture being slidably disposed in the axial passage with the surgical needle and knotted loop extending from the port at the distal end of the axial passage; and means at the proximal end of the shaft for securing and selectively applying axial tension on the proximal end of the suture, whereby the knotted loop may be held against the port and closed by applying such tension. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

- 19. A sterilized length of suture having a proximal end, a distal end, and a surgical needle secured to the distal end, wherein a loop is preformed with a slip knot at a location proximal of the surgical needle, wherein said slip knot is formed as illustrated in FIGS. 5A to 5E.

21. A method for suturing a wound in tissue, said method comprising:
-
introducing the distal end of a shaft proximate said wound, wherein said distal end carries a preformed knotted loop in a length of suture; passing a surgical needle at a distal end of the suture through the tissue across the wound while the knotted loop remains on the distal end of the shaft; passing the surgical needle through the preformed knotted loop to form a secondary loop in the suture while the knotted loop remains on the distal end of the device; applying axial tension on a proximal portion of the suture to close the knotted loop against the distal end of the shaft; and applying tension on a distal portion of the suture to close the secondary loop and to bind the wound. - View Dependent Claims (22, 23, 24, 25, 26, 27)
