Abstract
Abstract The invention is a suture with needle end, cord of latch notches, and latch collar end. The latch collar has a latch passage therethrough. The needle followed by latch notches is pulled through the tissue and the needle followed by a selective number of latch notches is continued on through the collar latch passage and severance is then made above the last notch pulled through the latch collar as it thus is latched on the tissue surface to complete a stitch much more quickly than can be done by conventionally tying a suture knot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A suture including a needle and a unitary, resilient, selflatching suture cord having successively after the needle, a series of latch notches, a connector portion, and a latch collar from which the connector portion extends, the latch collar providing a shaped notch passage therethrough with the latch collar yielding resiliently to permit latch notches following the needle to be pulled in selective number through the latch passage and with said latch notches being resiliently yieldable and shaped so that the last notch pulled through the latch collar returns to initial shape and relative position to latch cord and to latch upon latch collar upper surface.
Claim 2
Dependent Claim
105 words
A suture including a needle and a unitary, resilient, selflatching suture cord having successively after the needle, a series of latch notches, a connector portion, and a latch collar from which the connector portion extends, the latch collar providing a shaped notch passage therethrough with the latch collar yielding resiliently to permit latch notches following the needle to be pulled in selective number through the latch passage and with said latch notches being resiliently yieldable and shaped so that the last notch pulled through the latch collar returns to initial shape and relative position to latch cord and to latch upon latch collar upper surface.
Claim 3
Dependent Claim
34 words
A suture as claimed in claim 1 in which said suture cord between said latch notches is easily severable whereby the needle with leading notches may be detached by severance above said last notch.
Claim 4
Dependent Claim
21 words
A suture as claimed in claim 1 in which said latch notches are of truncated, tetrahedeal, pyramidal shape with bases downwardly.
Claim 5
Dependent Claim
20 words
A suture as claimed in claim 1 in which said latch notches are of truncated conical shape with bases downwardly.
Claim 6
Dependent Claim
21 words
A suture as claimed in claim 1 in which said latch notches are of truncated trihedral, pyramidal shape with bases downwardly.
Claim 7
Dependent Claim
17 words
A suture as claimed in claim 1 in which said latch notches are of flattened spheroid shape.
Claim 8
Dependent Claim
30 words
A suture as claimed in claim 1 in which said latch notches are of substantially triangular cross section with bases downwardly and extending on one side of the latch cord.
Claim 9
Dependent Claim
69 words
A suture as claimed in claim 1 in which said latch notches are of substantially triangular cross section with bases downwardly and extending on one side of the latch cord, in which the needle puncture end is arched to the same side as that to which the notch bases extend, and in which the base end of the needle is bonded with the lead end of the latch cord.
Claim 10
Dependent Claim
15 words
A suture as claimed in claim 1 which is comprised of a resilient plastic material.
Claim 11
Dependent Claim
18 words
A suture as claimed in claim 1 in which the latch cord connector is of flattened cross section.
