Breast cancer affects 1 in 8 women worldwide.

40% of women undergo a mastectomy for their cancer treatment and only 20% of women on average will have access to breast reconstruction procedures.

Current reconstruction techniques do not always provide a satisfactory result.  There are silicone implants that are permanent and risky and also autologous techniques that are either complicated, costly or iterative which can involve up to 8 surgeries to achieve a complete reconstruction.

Lattice Medical developed the MATTISSE bioprosthesis. A resorbable Tissue Engineering Chamber that allows for a more natural breast reconstruction which provides the following benefits to the patient:

  • Natural feel and aesthetic, thanks to the regeneration of autologous breast fat tissue.
  • Simple and unique.  The implant is completely resorbed by the body with the surgical procedure taking less than 1 hour to complete in most cases.
  • Closer to the lost self-image, thanks to 3D printing, Lattice Medical are able to make implants adapted to the morphology.
    Once implanter, the device regenerates the autologous fat tissue in only 6 months. The implant is resorbed after 18 months.

Jury Statement:

“The use of 3D printing to create patient-specific breast implants using the patient’s own body material can be a game-changer in the field of biocompatible implants.  The winner in the category Lattice Medical has made a significant contribution towards fighting cancer and improving women’s health and well-being.”
