Segmentally rigid suture and suturing technique

摘要

The suture device of the present disclosure disposes rigid components on suture, enabling the device to resist tensile and compressive loads and to protect soft tissue from suture pull-through. The suture device generally comprises of at least one rigid segment as well as a standard high tensile strength suture to create a segmentally rigid suture device. The at least one rigid segment may be comprised of any of a number of materials that are appropriate for use in the human body and provide the desired strength and stiffness for a particular application. Although the segmentally rigid suture device could be used with any prior art suture configuration, a grip stitch, a knot tying grip stitch, a straight-line grip stitch, and a reverse straight-line grip stitch suture configuration are described.

主权项

1. A suture device for affixing soft tissue with a stitch having at least one suture pass into the soft tissue, the device comprising:
a suture composed of a suture material; and at least one segment disposed on the suture and composed of a second material, the at least one segment being at least longitudinally rigid, the at least one segment embedded in an external portion of the suture passing over an exterior of the at least one segment, the at least one segment affixed to an internal portion of the suture passing through the at least one segment, the suture comprising at least one retention feature disposed on a length of the suture, the at least one retention feature limiting a position of the at least one segment on the length of the suture, the at least one segment configured to be disposed adjacent an outside surface of the soft tissue in the stitch adjacent the at least one suture pass, the at least one segment configured to support the suture device against the outside surface of the soft tissue and a compressive load on the soft tissue by the suture at the at least one suture pass.
