Coated looped suture
A suture including a reinforced loop is described herein. The suture includes an elongate body including a proximal section and a distal section, wherein the distal section includes first and second overlapping sections and a loop. A polymeric coating is positioned on at least a portion of the distal section to reinforce the loop.
1. A suture comprising:
an elongate body including a proximal section and a distal section, the distal section including a first section overlapping a second section, a loop, and a distal aperture defined within the loop; and
a polymeric coating positioned on only a portion of the loop and across only a portion of the distal aperture that is distal to, and in spaced relation from, the first and second sections to reinforce the loop.
2. The suture of claim 1 , wherein the elongate body comprises a biocompatible material.
3. The suture of claim 1 , wherein the first and second sections are secured together by at least one method selected from the group consisting of glues, adhesives, solvents, heat, and ultrasonic energy.
4. The suture of claim 1 , wherein the first and second sections are secured together by ultrasonic energy.
5. The suture of claim 1 , wherein the first section further comprises a tapered end.
6. The suture of claim 5 , wherein the tapered end of the first section angles downwardly towards the proximal section of the elongate body.
7. The suture of claim 1 , wherein the polymeric coating comprises a material selected from the group consisting of polylactic acids, polyglycolic acids, polylactide-co-glycolide copolymers, polytrimethylene carbonate, poly-{acute over (ε)}-caprolactone, poly-dioxanone, polyhydroxyalkanoates, polyphosphasenes, polypropylene fumarates, polyanhydrides, polyorthoesters, polyimides, polyurethanes, polyurethaneureas, perfluoroalkoxy polymers, florinated ethylene/propylene copolymers, polyanhydride esters, polysaccharides, polyethylene-lactone copolymers, polyethylene-polyorthoester copolymers, polymer drugs, hydrophilic vinyl polymers, phosphoryl cholines, hydroxamates, vinyl furanones, quarternary ammoniums, alkylene oxides, collagen, elastin, keratin, fibrin, and blends, copolymers, homopolymers, and combinations thereof.
8. The suture of claim 1 , wherein the polymeric coating comprises copolymers of poly(glycolide-co-trimethylene carbonate).
9. The suture of claim 1 , wherein the polymeric coating further comprises at least one coating aperture.
10. The suture of claim 9 , wherein the at least one coating aperture is defined within a portion of the polymeric coating that spans the distal aperture.
11. The suture of claim 1 , wherein the suture comprises a monofilament suture.
12. The suture of claim 1 , wherein the elongate body includes barbs.
13. A suture comprising:
an elongated body including a proximal section and a distal section, the distal section including a first section overlapping a second section, a loop, and a distal aperture defined within the loop; and
a polymeric coating completely covering the loop and the distal aperture.
14. The suture of claim 13 , wherein the polymeric coating is positioned on at least a portion of the first and second sections.
15. The suture of claim 13 , wherein a distalmost end of the distal section defines a distal end of the loop, and adjacent surfaces of the first and second sections are fixedly joined together at a proximalmost end of the first section.
16. The suture of claim 15 , wherein the polymeric coating is not positioned on the proximalmost end of the first section.
