Compliance control stitch patterns sewn or embroidered into biotextile or medical textile substrates impart reinforcing strength, and stretch resistance and control into such substrates. Compliance control stitch patterns may be customizable to particular patients, substrate implantation sites, particular degenerative or diseased conditions, or desired time frames. Substrates having compliance control stitch patterns sewn or embroidered into them may be used in tissue repair or tissue reconstruction applications.

The conductive thread embroidery proceeds from a first point outside a segmented area set on a sheet material to a second point on the segmented area. An embroidery with the conductive thread is sewn from the second point as a starting point to attach a segment in the segmented area. This series of steps is performed without performing a process for cutting the conductive thread by stopping the sewing process of the conductive thread.

After folding and sewing, the method can include cutting a portion of each fold where the seam associated with the first set of markings intersects with the other set of markings. The method can include folding down the fabric top along a marking of a second set of markings to produce a fold and sewing a seam along the fold, repeating the folding and sewing steps for each marking of the second set of markings.

Described herein are implants (e.g., medical textiles / biotextiles) that include nonuniform stitching patterns to reinforce and bolster the tensile strength of a substrate base and provide customized compliance characteristic to the implant. In some examples, the nonuniform stitching pattern does not substantially change the compliance of the implant relative to the substrate in directions along a plane of the substrate. In some examples, the nonuniform stitching pattern creates a nonuniform directional compliance characteristic to the implant. The implants may be configured as surgical grafts that may be used for soft tissue reconstruction, regeneration, or repair.
