Abstract
A strand that can be used to support repair of a soft tissue injury is disclosed. The strand comprises high strength collagen fibers and high strength biocompatible fibers, such as polyethylene fibers arranged into a strand that can be used as part of a suture or other scaffold for the repair of joints and soft tissues, such as ligaments and tendons. The fibers may be over-braided around a central core, which is itself comprised of two or more fibers. The high strength collagen fibers are strong enough to withstand the stresses imposed by industrial braiding machines and processes.
Claims22
An implantable biopolymer scaffold, the scaffold including at least one braided strand, the braided strand consisting essentially of high strength collagen fibers and high strength biocompatible fibers.
An implantable biopolymer scaffold, the scaffold comprising:
- a set of high strength collagen fibers braided with a set of high strength polyethylene fibers;
- wherein a high strength collagen fiber of the set of high strength collagen fibers has a first ultimate tensile strength, and wherein a high strength polyethylene fiber of the set of high strength polyethylene fibers has a second ultimate tensile strength;
- and
- wherein the first ultimate tensile strength is at least one percent of the second ultimate tensile strength.
A braided strand comprising a plurality of high strength collagen fibers and high strength polyethylene fibers.
A braided strand comprising:
- a set of high strength collagen fibers braided with a set of high strength polyethylene fibers;
- wherein a high strength collagen fiber of the set of high strength collagen fibers has a first ultimate tensile strength, and wherein a high strength polyethylene fiber of the set of high strength polyethylene fibers has a second ultimate tensile strength;
- and
- wherein the first ultimate tensile strength is at least about one percent of the second ultimate tensile strength.
