Abstract

Claims (25)

1 . A medical device comprising:

a mesh suture having a first end and a second end located away from the first end, the mesh suture including a porous flat strip including a plurality of fibers extending between the first end and the second end, at least one fiber of the plurality of fibers being configured to attach a surgical needle to the first end of the mesh suture, and a plurality of pores extending through the porous flat strip, the plurality of pores including pores in a size range of 200 microns to 4 millimeters, the pores being adapted to facilitate tissue integration through the porous flat strip when the mesh suture is configured to be introduced into a body.

2 . The medical device of claim 1 , further comprising:

the surgical needle attached to the first end of the mesh suture.

3 . The medical device of claim 2 , further comprising:

the surgical needle attached to the second end of the mesh suture.

4 . The medical device of claim 2 , further comprising:

an intervening segment disposed between and connected to the first end of the mesh suture and the surgical needle.

5 . The medical device of claim 4 , wherein the intervening segment comprises one or more fibers of the plurality of fibers extending from the first end of the mesh suture and has a cross-sectional dimension that is smaller than a width of the mesh suture.

6 . The medical device of claim 4 , wherein the intervening segment comprises more than one of the plurality of fibers converging into a bundled configuration.

7 . The medical device of claim 4 , wherein the intervening segment is non-porous.

8 . The medical device of claim 2 , further comprising:

multiple intervening segments disposed between the first end of the mesh suture and the surgical needle, the multiple intervening segments being connected together to attach the surgical needle to the first end of the mesh suture.

9 . The medical device of claim 1 , wherein the mesh suture is constructed of a material selected from the group consisting of: polyethylene terephthalate, nylon, polyolefin, polypropylene, silk, polymers p-dioxanone, co-polymer of p-dioxanone, ε-caprolactone, glycolide, L(−)-lactide, D(+)-lactide, meso-lactide, trimethylene carbonate, polydioxanone homopolymer, metal fibers, poly-4-hydroxybutyrate, steel, titanium, fibers derived from spider silk, graphene, and combinations thereof.

10 . The medical device of claim 1 , wherein the mesh suture is at least 20 centimeters in length.

11 . The medical device of claim 1 , wherein the porous flat strip has a width from 3 millimeters to 40 millimeters.

12 . The medical device of claim 1 , wherein the porous flat strip extends the entire length of the mesh suture.

13 . The medical device of claim 1 , wherein the plurality of fibers are braided, knitted, woven, extruded, or fused together.

14 . The medical device of claim 1 , further comprising:

the surgical needle attached to the first end of the mesh suture; and

a non-porous intervening segment disposed between the surgical needle and the first end of the mesh suture, the intervening segment comprising one or more fibers of the plurality of fibers extending from the first end of the mesh suture and having a cross-sectional dimension that is smaller than a width of the mesh suture,

the mesh suture being constructed of a material selected from the group consisting of: polyethylene terephthalate, nylon, polyolefin, polypropylene, silk, polymers p-dioxanone, co-polymer of p-dioxanone, ε-caprolactone, glycolide, L(−)-lactide, D(+)-lactide, meso-lactide, trimethylene carbonate, polydioxanone homopolymer, metal fibers, poly- 4 -hydroxybutyrate, steel, titanium, fibers derived from spider silk, graphene, and combinations thereof,

the mesh suture being at least 20 centimeters in length,

the porous flat strip having a width from 3 millimeters to 40 millimeters and extending the entire length of the mesh suture, and

the plurality of fibers being braided, knitted, woven, extruded, or fused together.
