Abstract

Textile surgical articles are disclosed which are constructed in whole or in part from high tenacity low elongation fibers such as ultra-high molecular weight extended chain polyethylene high tenacity fibers. The products may be braided, woven or knitted, such as braided tapes, hollow braids and spiroid braids. The high tenacity low elongation fibers provide structures having greatly increased strength and decreased elongation, a combination of properties which is uniquely applicable and superior for repairing body tissue. The products may be plasma treated to reduce slip.

Claims

1. A method for repairing split portions of body tissue comprising looping a flexible elongated member about the body tissue in a manner to attach the portions in adjacent engaged relation to promote natural healing thereof, said flexible member being formed at least in part of first fibers of ultra-high molecular-weight high tenacity material and at least second fibers which differ from said first fibers and are formed from a non-absorbable material, said first and second fibers being braided to form said elongated member.

2. The method of claim 1 wherein the molecular weight of said fibers is within the range of from about 500,000 to about 5 million.

3. The method of claim 2 wherein said fibers comprise high tenacity extended chain polyethylene fibers.

4. The method of claim 1 wherein said elongate member has an elongation to break below about 15%.

5. The method according to claim 1 wherein said elongate member is of a flat braided construction.

6. The method according to claim 1 wherein said elongate member is of hollow braid construction.

7. The method according to claim 6 wherein said hollow braid contains a core.

8. The method according to claim 1 wherein said elongated member is of spiroid braid construction.

9. The method according to claim 8 wherein said spiroid braid has a substantially circular cross-sectional shape.

10. The method according to claim 1 wherein said elongated member has a straight pull greater than about 35 kg.

11. The method according to claim 1 wherein said second non-absorbable fibers are formed from nylon.

12. The Method according to claim 1 wherein said second non-absorbable fibers are formed from polyester.
