Tissue interface incorporating multiple layers

A tissue interface configured to be positioned at a tissue site, the tissue interface comprising:

• a first tissue interface layer comprising a plurality of protrusions extending from a first surface of the first tissue interface layer;
• a second tissue interface layer comprising a plurality of protrusions extending from a first surface of the second tissue interface layer in a direction towards the first tissue interface layer, wherein the first surface of the first tissue interface layer faces the first surface of the second tissue interface layer, and wherein at least some of the plurality of protrusions extending from the first surface of the first tissue interface layer are aligned with at least some of the protrusions extending from the first surface of the second tissue interface layer;
• and
• a bonding layer coupling the first tissue interface layer to the second tissue interface layer using a bonding layer spot segment positioned between each of the aligned protrusions, wherein the first tissue interface layer is configured to decouple from the second tissue interface layer when an effective bonding strength of the bonding layer is exceeded to reduce a thickness of the tissue interface.

A tissue interface configured to be positioned at a tissue site, the tissue interface comprising:

• a first tissue interface layer divided into a plurality of separate segments;
• a second tissue interface layer;
• and
• a bonding layer positioned between the first tissue interface layer and the second tissue interface layer and coupling each of the plurality of separate segments of the first tissue interface layer to the second tissue interface layer, wherein at least one separate segment of the plurality of separate segments of the first tissue interface layer is configured to decouple from the second tissue interface layer when an effective bonding strength of the bonding layer is exceeded to reduce a thickness of the tissue interface.

A tissue interface configured to be positioned at a tissue site, the tissue interface comprising:

• a first tissue interface layer;
• a second tissue interface layer;
• and
• a bonding layer positioned between the first tissue interface layer and the second tissue interface layer, wherein the bonding layer covers a portion of a surface of each of the first tissue interface layer and the second tissue interface layer that is less than an entire portion of the surface of each of the first tissue interface layer and the second tissue interface layer, wherein the bonding layer couples the first tissue interface layer to the second tissue interface layer, and wherein the first tissue interface layer is configured to decouple from the second tissue interface layer when an effective bonding strength of the bonding layer is exceeded to reduce a thickness of the tissue interface.
