Adaptive Sutures Dynamically Changing Wound Holding Properties Post-Implantation
The present invention is directed to a length adaptive surgical suture comprising a monofilament or a braid of a plurality of filaments, the suture having an original length when implanted and a second length that is different from the original length within a first twenty-four (24) hour period of time after implantation to accommodate tissue swelling. The present invention is also directed to configurations and combinations that enable length adaptive results.

SMALL DIAMETER FIBER BRAID WITH CENTRAL CORE MEMBER
A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.
