Abstract
Medical constructs with twisted cables formed from a plurality of collagen fibers twisted together to form strands and those strands twisted together to form cables and relate methods of twisting the collagen fibers to form the medical constructs while holding the fibers and strands of fibers in tension and twisting in a first direction (i.e., in a clockwise direction), then twisting them in a second opposing (counterclockwise) direction for a number of twists per inch.
Claims19
A medical construct, comprising:
- at least one biocompatible cable comprising a plurality of strands twisted together a number of twists per fiber meter in a first rotative direction,
- wherein each strand comprises a plurality of parallel arrays of long collagen fibers produced from pepsin solubilized collagen twisted together a number of twists per fiber meter in a second rotative direction opposite the first rotative direction, said number of twists per fiber meter in the second rotative direction being substantially the same in each of the strands, wherein the medical construct has a length between 10 cm and 15 cm,
- wherein the number of twists per fiber meter in the second rotative direction is between about 50%-300% that of the number of twists per fiber meter in the first rotative direction,
- wherein the strands each have between about 10-1000 twists per fiber meter in the first and second rotative directions, and wherein the at least one biocompatible cable has a denier that is between about 20 to about 80.
