Abstract

Methods and apparatuses are disclosed relating to the creation and use of bespoke wound fillers and other wound treatment apparatuses. Some embodiments provide for the creation of bespoke wound fillers based on characteristics of a wound. Certain embodiments also include the use of bespoke wound fillers in combination with negative pressure to treat a wound.

Claims (17)

1. A method of manufacturing a bespoke tissue engaging apparatus, the method comprising:

creating a three-dimensional model of a bespoke tissue engaging apparatus using a repeating building block based on a three-dimensional model of an area to be treated; and

fabricating a bespoke tissue engaging apparatus based on the created three-dimensional model of the area to be treated, wherein the bespoke tissue engaging apparatus comprises at least a first plurality of identical repeating sections configured to collapse in a manner determined by the three-dimensional model to account for attributes of the area to be treated.

2. The method of claim 1 , wherein the bespoke tissue engaging apparatus is fabricated with a three-dimensional printer.

3. The method of claim 1 , wherein the bespoke tissue engaging apparatus comprises a porous material.

4. The method of claim 1 , wherein the three-dimensional model of an area to be treated comprises repeating blocks having different characteristics for positioning in different parts of the area to be treated.

5. The method of claim 1 , wherein the area to be treated comprises bone.

6. The method of claim 1 , wherein the bespoke tissue engaging apparatus is fabricated from two or more different materials.

7. The method of claim 1 , wherein the bespoke tissue engaging apparatus comprises a plurality of elongate strips.

8. The method of claim 7 , wherein the bespoke tissue engaging apparatus comprises a plurality of intervening members connecting the elongate strips, wherein the plurality of intervening members are configured to pivot relative to the strips to allow the plurality of elongate strips to collapse relative to one another.

9. The method of claim 8 , wherein the intervening members between a first strip and a second strip are configured to pivot independently of the intervening members between a second strip and a third strip.

10. The method of claim 1 , wherein the bespoke tissue engaging apparatus comprises a polymer.

11. The method of claim 1 , wherein the bespoke tissue engaging apparatus is in the shape of an oval.

12. The method of claim 1 , wherein the bespoke tissue engaging apparatus comprises tissue anchors, the tissue anchors configured to engage tissue.

13. The method of claim 8 , wherein the plurality of intervening members between adjacent elongate strips define a row of cells between each pair of adjacent elongate strips.

14. The method of claim 13 , wherein the cells in a row between adjacent elongate strips are configured to collapse together as the adjacent strips collapse relative to one another.

15. The method of claim 3 , wherein the bespoke tissue engaging apparatus comprises foam.
