Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A suture applier comprising: a shaft having proximal and distal ends; a length of suture having proximal and distal ends, a surgical needle at the distal end of the suture, and a knotted loop disposed on the suture proximally of the needle, said suture being axially aligned with the shaft with the surgical needle and axial loop extending from the distal end of the shaft and with the proximal end of the suture extending from the proximal end of the shaft, whereby axial tension may be applied on the proximal end of the suture in order to close and tighten the loop.
Claim 2
Dependent Claim
102 words
A suture applier comprising: a shaft having proximal and distal ends; a length of suture having proximal and distal ends, a surgical needle at the distal end of the suture, and a knotted loop disposed on the suture proximally of the needle, said suture being axially aligned with the shaft with the surgical needle and axial loop extending from the distal end of the shaft and with the proximal end of the suture extending from the proximal end of the shaft, whereby axial tension may be applied on the proximal end of the suture in order to close and tighten the loop.
Claim 3
Dependent Claim
40 words
A suture applier as in claim 1, further comprising an axially aligned track at the proximal end of the shaft, a handle slidably received in said track, and means on the handle for retaining the proximal end of the suture.
Claim 4
Dependent Claim
23 words
A suture applier as in claim 1, further comprising means at the distal end of the shaft for removably securing the surgical needle.
Claim 5
Dependent Claim
32 words
A suture applier as in claim 3, wherein the means for removably securing the surgical needle comprises a port in the distal tip of the shaft having penetrable material behind said port.
Claim 6
Dependent Claim
49 words
A suture applier as in claim 4, further comprising an additional port in side wall of the shaft having penetrable material behind said port, whereby the surgical needle is secured after use and the suture is tensioned to facilitate trimming of the tail ends after the suture is tied.
Claim 7
Dependent Claim
27 words
A suture applier as in claim 1, further comprising means at the distal end of the shaft for detachably securing a free end of the knotted loop.
Claim 8
Dependent Claim
24 words
A suture applier as in claim 6, wherein said means for detachably securing a free end of the knotted loop on an elastic band.
Claim 9
Dependent Claim
34 words
A suture applier as in claim 7, further comprising a second elastic band spaced proximally from the first for detachably securing a portion of the suture between the surgical needle and the knotted loop.
Claim 10
Dependent Claim
23 words
A suture applier as in claim 1, wherein the knotted loop includes a slip knot formed as illustrated in FIGS. 5A to 5E.
