The subject matter of this invention is a heat distribution management device in a treatment device of wires in movement on a means of transport, said means of transport being able to be traversed by a flow of heat at or through the of orifices, characterized in that the device comprises at least one means of sealing by coverage of at least one part of the orifices of the means of transport, said means of sealing being independent of the means of transport.

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.
