Systems and methods for using structured tissue augmentation constructs in soft tissue fixation repair

A surgical kit, comprising

• a structured tissue augmentation construct having a first tissue-engaging surface with a surface area defined by a length and a width of the construct and a second surface with a surface area defined by the length and the width of the construct, the second surface being opposed to the first tissue-engaging surface and a thickness of the construct being defined by a distance between the first tissue-engaging surface and the second surface, the surface areas of the first tissue-engaging surface and the second surface being larger than the surface areas of any other sides of the construct and the thickness being the shortest of the length, the width, and the thickness of the construct, the structured tissue augmentation construct including;
• a support skeleton at least partially integrated with the tissue augmentation construct such that flexing of the construct induces a corresponding flexing of at least a portion of the support skeleton, the support skeleton being configured such that it is biased in an expanded configuration that in turn causes the structured tissue augmentation construct to expand, wherein the support skeleton comprises a spine extending along at least a portion of the length of the construct, a plurality of first ribs extending from the spine along the width of the construct in a first direction towards a first lateral end of the construct, and a plurality of second ribs extending from the spine along the width of the construct in a second direction towards a second lateral end of the construct;
• and
• a suture coupled at a first end of the spine and braided around at least a portion of a length of the spine, the suture including a first tail configured to extend from a first longitudinal end of the construct and a second tail configured to extend from a second longitudinal end of the construct;
• and
• a delivery tube configured to contain the structured tissue augmentation construct in a constricted arrangement.

A structured surgical construct, comprising:

• a tissue augmentation block having a first tissue-engaging surface with a surface area defined by a length and a width of the block and a second surface with a surface area defined by the length and the width of the block, the second surface being opposed to the first tissue-engaging surface and a thickness of the block being defined by a distance between the first tissue-engaging surface and the second surface, the surface areas of the first tissue-engaging surface and the second surface being larger than the surface areas of any other sides of the block and the thickness being the shortest of the length, the width, and the thickness of the block;
• and
• a support skeleton at least partially integrated with the tissue augmentation block such that flexing of the tissue augmentation block induces a corresponding flexing of at least a portion of the support skeleton, the support skeleton being configured such that it is biased in an expanded configuration that in turn causes the tissue augmentation block to expand, wherein the support skeleton further comprises:
• a spine extending along at least a portion of the length of the block;
• a plurality of first support elements extending from the spine along the width of the block in a first direction towards a first end of the block;
• a plurality of second support elements extending from the spine along the width of the block in a second direction towards a second end of the block, a distance between the first and second ends defining the width of the block, and
• a suture braided around the spine.
