Bespoke wound treatment apparatuses and methods for use in negative pressure wound therapy
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.
1. A method of manufacturing a bespoke tissue treatment apparatus for use in treating a damaged region of tissue, the method comprising:
scanning a tissue location to obtain a three-dimensional model of an area to be treated;
modifying the three-dimensional model of the area to be treated to generate a three-dimensional model of a bespoke tissue treatment apparatus using a repeating building block, wherein said modifying accounts for attributes of the tissue location and for a treatment modality; and
fabricating a bespoke tissue treatment apparatus based on the generated three-dimensional model of a bespoke tissue treatment apparatus.
2. The method of claim 1 , wherein the three-dimensional model of an area to be treated is obtained using a device selected from the group consisting of laser scanners, stereo-optical scanners, and cameras with depth sensors.
3. The method of claim 1 , wherein the area to be treated comprises bone.
4. The method of claim 1 , wherein the area to be treated comprises a ligament.
5. The method of claim 1 , wherein the three-dimensional model of a bespoke tissue treatment apparatus comprises repeating blocks having different characteristics for positioning in different parts of the area to be treated.
6. The method of claim 1 , wherein modifying the three-dimensional model of an area to be treated accounts for one or more tissue types present in the area to be treated.
7. The method of claim 1 , wherein the bespoke tissue treatment apparatus is fabricated with a three-dimensional printer.
8. The method of claim 1 , wherein modifying the three-dimensional model of an area to be treated comprises determining a suitable porosity for the bespoke tissue treatment apparatus.
9. The method of claim 1 , wherein the three-dimensional model of the bespoke tissue treatment apparatus has variable porosity.
10. The method of claim 1 , wherein fabricating the bespoke tissue treatment apparatus comprises fabricating a first portion of the bespoke tissue treatment apparatus using a first porosity, and fabricating a second portion of the bespoke tissue treatment apparatus using a second porosity, the first porosity being smaller than the second porosity.
11. The method of claim 1 , wherein the bespoke tissue treatment apparatus is fabricated from a polymer.
12. The method of claim 1 , wherein the bespoke tissue treatment apparatus is fabricated from a porous scaffolding material.
13. The method of claim 1 , further comprising seeding the bespoke tissue treatment apparatus with one or more of cells or cell growth promoters.
14. The method of claim 1 , wherein the bespoke tissue treatment apparatus is fabricated from two or more different materials.
15. The method of claim 10 , wherein the first porosity comprises pores measuring between about 20 to 150 μm and the second porosity comprises pores measuring between about 400-3000 μm.
