Implants with corner-lock stitch patterns

An implant, comprising:

• a substrate comprising a biocompatible material;
• and
• a reinforcing mesh sewn into the substrate, the reinforcing mesh including:
• a corner-stitch pattern comprising:
• a first lock-stitch pattern including a first upper thread and a first lower thread that are interlaced at first thread interlace points;
• and
• a second lock-stitch pattern including a second upper thread and a second lower thread that are interlaced at second thread interlace points, wherein the second lock-stitch pattern overlaps the first lock-stitch pattern such that the second upper thread and the second lower thread envelop the first upper thread and the first lower thread adjacent to the at least one of the first thread interlace points and at least one of the second thread interlace points;
• and
• a straight stitch laid across the first and second lock-stitch patterns.

A method of forming an implant, the method comprising:

• sewing a reinforcing mesh into a substrate, the substrate comprising a biocompatible material, wherein forming the reinforcing mesh comprises:
• sewing a first lock-stitch pattern into the substrate, wherein the first lock-stitch pattern includes a first upper thread and a first lower thread that interlace at at least one first thread interlace point;
• and
• sewing a second lock-stitch pattern into the substrate, wherein the second lock-stitch pattern includes a second upper thread and a second lower thread that interlace at at least one second thread interlace point, wherein the second lock-stitch pattern overlaps the first lock-stitch pattern such that the second upper thread and the second lower thread envelop the first upper thread and the first lower thread adjacent to the at least one first thread interlace point and the at least one second thread interlace point.
