Abstract: Methods, systems, and devices for changing cross-sectional sizes and/or shapes of flat braided sutures and the resulting constructs are disclosed. The flat braided sutures can have a textile first cross-sectional shape that can be changed to a textile second cross-sectional shape. The systems can have a heater and a die. The flat braided sutures can be movable through the heater and the die. When the flat braided sutures are in the heater, the flat braided sutures can be heatable from a textile first temperature to a textile second temperature greater than the textile first temperature. When the flat braided sutures are at the textile second temperature, the textile first cross-sectional shape can be changeable to the textile second cross-sectional shape.

Abstract: Methods and systems for braiding sutures and the resulting constructs are disclosed. The sutures can have alternating bifurcated and non-bifurcated lengths. The sutures can have looped- ends, with both ends of the loop having contiguous braiding with the adjacent body or remainder of the suture. Braiding machines can have one or more bifurcating bars that can controllably obstruct or allow passage of the shuttle and carriers of the braiding machine. The controllable bifurcating bars can result in u-turns in the shuttle and carrier paths, such as a path encircling a horngear adjacent to the bifurcating bar, or passage of the shuttle and carrier across the bifurcating bar.
