Abstract

A needle-suture combination includes a suture having first and second portions, the first portion having a pliability greater than that of the second portion. The needle is preferably a double tipped shuttle needle having a lateral aperture into which the suture is affixed. In one embodiment the first portion of the suture is multifilament suture material that is connected to a monofilament second portion by means of shrink wrap type tubing. In another embodiment the entire suture is an integral length of monofilament material, the first portion being a reduced diameter section of the monofilament suture.

Claims

1. A needle-suture combination, which comprises:

a) a surgical needle having a pointed tip at each of two ends and a lateral suture receiving aperture disposed between the two ends; and

b) a suture attached to the surgical needle, said suture having a first multifilament suture portion and second monofilament suture portion, said first suture portion being characterized by a pliability which is greater than the pliability of the second suture portion.

2. The needle-suture combination of claim 1, wherein the multifilament first portion has a first end inserted into the aperture of the needle and a second end connected to a first end of the monofilament second portion.

3. The needle-suture combination of claim 2, wherein the second end of the multifilament first portion of the suture and the first end of the monofilament second portion of the suture are connected by a shrinkable tubing.

4. The needle-suture combination of claim 3, wherein the shrinkable tubing has an outer diameter which is greater in the middle of the tubing than at the ends.

5. The needle-suture combination of claim 1, wherein the multifilament first portion has a length to diameter ratio of from about 5 to about 12.

6. The needle-suture combination of claim 1, wherein the needle is fabricated from a material selected from the group consisting of series 300 stainless steel alloy, series 400 stainless steel alloy, and non-ferrous alloy.

7. The needle-suture combination of claim 1, wherein the suture is fabricated from a non-bioabsorbable material selected from the group consisting of silk, nylon, polyolefin, polyester, linen and cotton.

8. The needle-suture combination of claim 1, wherein the suture is fabricated from a bioabsorbable material selected from the group consisting of polymers of glycolide, lactide, p-dioxanone, caprolactone, trimethylene carbonate, and physical and chemical combinations thereof.

9. A needle-suture combination, which comprises:

a) a surgical needle having a pointed tip at each of two ends and a lateral suture receiving aperture disposed between the two ends; and

b) an integral monofilament suture attached to said surgical needle, said suture having first and second portions, said first suture portion having a diameter from about 20% to about 8% of the diameter of the second suture portion and being characterized by a pliability which is greater than the pliability of the second suture portion.

10. A needle-suture combination, which comprises:

a) a surgical needle; and

b) a suture attached to said surgical needle, said suture having first and second portions, said first suture portion being disposed between the surgical needle and the second suture portion and being characterized by a pliability which is greater than the pliability of the second suture portion, wherein the first suture portion is a multifilament suture portion and the second suture portion is a monofilament suture portion.
